Bohol is admirable as it is uncomplicated. There are surely a lot more places to discover as we're only exploring it for a day. From Cebu, we took an Oceanjet Ferry to Tagbilaran Port and got ourselves ready for the whole day adventure.</div>

History is always a first stop and usually on a morning as kids get bored after lunch. There's a tour guide that tells us about the 400 year old history of the church, toured us around the relics and gold and silver statues of Catholic Saints. </div>
<div class="separator" style="clear: both; text-align: left;">

The painted ceiling inside the church and it's intricately design altar is a stunner. You will be amazed how in an unassuming place like Bohol such a grandeur was hidden beneath. </div>

What's best to educate the kids than to bring them to places where they can see the animals in their books in the flesh. There's an adorable butterfly farm but in here they also saw a giant yellow snake and sleeping lemurs.It's also a best place to buy your souvenir or 'pasalubong" as they have an assortment of good from delicacies to merchandise like ref magnets and shirts on the restaurant in the place.</div>

This can be a highlight of the trip for it is as satisfying as it is amazing. Get relaxed as you are serenaded on a floating restaurant while eating all you can.

This is a short side-trip of the Loboc River Cruise. It looks like a showcase of the Ati Tribe way of life and also an opportunity for them to earn a little when you buy their hand-made souvenirs like bow and arrows for kids. They also have an area for photo opportunity with them with a fire show surprise during the picture taking.</div>

Kids always get amazed with animals. Tarsiers or mamags are one of the smallest primates. They are just so small about the size of my siz-year old Pochi's fist. We followed the trail with a tour guide and took some photos of the sleeping tarsiers. It is very important during travel that we also teach the kids not to disturb the peaceful habitat of these endangered species. We asked them to walk and speak quietly so as not to wake the mamags up. </div>

The 3000 hectare forest planted by Boy Scouts 60 years ago. To me it's like Arashiyama Bamboo forest but this is just a more dangerous. There is no parking in the area so you only get to park the car on the side road. To get a clear shot with the trees on the road, you have to take a photo quickly as it is a curb and cars pass through quite frequently in that photo spot.</div>

The highlight of our Bohol visit is these natural wonder of the world. It's celebrated in our primary school text books so no more need to elaborate on this. It's prettier in person than in our books. I am star-strucked. We climbed the observatory to have a magnificent view of the 1776 kisses-shaped hills on Carmen Bohol. </div>

Bohol is an overall amazing province to visit. We're coming back because we have not yet explored its equally pretty beaches. There is also a very interesting view while we're strolling around the city, the TRICYCLES. It has bible verses on every commuter tricycle on the street. It was a sight to see as we also asked Pochi to read on those verses. Something like a sweet reminder to us to stay safe on our travels and God is along the way with us. </div>

When you've swept 27 provinces in four years with three kids on tow, the impact of a pandemic gets more dramatic. We're now of day-92 and it still feels like a sudden stop, the inertia of a fast-paced nomadic adventure is still there. The gravity that pulls us outside is still as strong.</div>

Last year we went tourist site hopping to 8 places for a Day in Bohol. Pochi is 6 years old that time and we heard no tantrum at all. Funny how we've visited 8 Places in 1 day, and now that we're in quarantine we're only staying in 1 place for 91 days.</div>

</div>
<div>
<ol>
<li><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">By Fixed number - randomly choose features based on a fixed number of sample that can be carried out by the team.</span></li>
<li><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">By grid or polygon - create an index grid and sample features per grid. </span></li>
<li><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">By percentage of features - determine the sampling percentage of all features. Amount of features for inspection/QC is based on direct percentage count or applied weights, if there is any.</span></li>
<li><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">By calculation - determine the statistically significant number of samples at a certain confidence interval, plus or minus the acceptable error. ( Given the sample size, how many features can fail inspection before my entire database fails.)</span></li>
</ol>
<div>
<div style="margin: 0in;">
<span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">The
sample size is determined based on four factors:</span></div>
<ul style="direction: ltr; margin-bottom: 0in; margin-left: .375in; margin-top: 0in; unicode-bidi: embed;" type="disc">
<li style="margin-bottom: 3pt; margin-top: 0pt; vertical-align: middle;"><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">The probability ( <span style="font-style: italic;">p</span>) of the outcome, that is, given a feature, the
probability of a “pass” versus a “fail.” This value is maximized at 0.5;
that is, since we have no prior knowledge of past probability that a
certain percent of features from a given client will pass or fail, there
is an equal probability of the features passing or failing, so 0.5 is the
value used in the tool. 0.5 represents the most pessimistic (conservative)
value when used in the equation for variance <span style="font-style: italic;">p</span>(1- <span style="font-style: italic;">p</span>). That is, <span style="font-style: italic;">p</span>(1 - <span style="font-style: italic;">p</span>) is maximized when <span style="font-style: italic;">p</span> = 0.5.</span></li>
<li style="margin-bottom: 3pt; margin-top: 0pt; vertical-align: middle;"><span style="color: #444444; font-family: "arial" , "helvetica" , sans-serif;">The population size (<span style="font-style: italic;">N</span>).</span></li>

fail the entire dataset, given a population size, confidence interval, and
specified failure ratio. Determination of failure threshold depends on three
factors:</span></div>

that were detected, then pass the dataset. If a dataset fails, it means that
the sample has revealed a deficiency with the entire dataset, not just the
detected failures. The quality of the entire dataset will have to be improved
to pass a retest based on a new random sample.</span></div>

My reading list on GIS has been a bit full so I tried to catch up over the weekend. </div>
<div>
On my plate are OSM data and political boundaries of Ph. I wonder what to map next, I want something close to my heart so I chose coffee.</div>
<div>
<br /></div>
<div>
I mapped all the hot and cold spots of cafe in the Philippines and clipped in a city-level polygon boundary. I then used Anselin Moran's I statistic to identify outliers in the clusters of cafe all over the country. Points below shows high negative z-values which means there are significantly high number of cafe in the following cities while it's neighborhood has significantly low number of cafe. </div>
<div>
<br /></div>
<div>
That interests me. Gives me more reason to look forward visiting those cities next. Of the 5 clusters, I have only been to Baguio and I must attest that cafe in that city has set the bar. I love the coffee that complements the cold weather.</div>
<div>
<br /></div>
<div>
Now I wonder how the other outlier locations were also an output of the analysis. I must discover it myself...</div>
<div class="separator" style="clear: both; text-align: center;">

<div>
<br /></div>
<div>
Now wondering where is are the high clusters of cafe in the country along with it's neighbors? Manila and neighboring provinces. Not quite a surprise. </div>

I just realized I never really used mapping for leisure or just about anything that I find interesting.<div>
<br /></div>
<div>
Now I plan to create more maps beyond my usual office stuff.</div>
<div>
<br /></div>
<div>
Here are some maps that I find interesting and might need further analyses.</div>
<div>
<br /></div>
<div>
<b>SCHOOLS:</b></div>
<div>
<br /></div>
<div>
I generated a hot spot map of all the schools in the Philippines using the recent Open Street Map data. Basically a hot spot counts the number of instances there is a school within the bounding polygon set for analysis. In this case, the bounding polygon I used are cities/municipalities.</div>
<div>
<br /></div>
<div>
I then generated an optimized hot spot analysis that basically checks which cities has neighboring cities with higher values or lower values as themselves. It uses the Getis Ord-Gi* statistic to generate probability or p-values to quantify clustering. These clusters of high values then generates a hot spot and cluster of low values generate a cold spot. </div>
<div>
<br /></div>
<div>
The darker red implies higher chances that this clustering among the neighboring cities is not a result of random chance hence the clustering is significant. </div>
<div>
<br /></div>
<div>
Cold spots on the other hand or the the blue ones are cities containing very low cluster of schools as compared to its neighboring cities. Cagayan region on the North and Marawi area on the south are classified as cold spots. </div>
<div>
<br /></div>
<div>
Light yellow on the other hand shows no significant clustering or neither hot or cold spot of schools in the Philippines. </div>
<div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://1.bp.blogspot.com/-L9Bgt2A8j8g/XSdZg5m3bYI/AAAAAAAADD0/lFl44QB1u2Ihi5obncebKpf6qDBb0o7HgCLcBGAs/s1600/school%2Bhotspots%2BPH.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1600" data-original-width="1237" height="640" src="https://1.bp.blogspot.com/-L9Bgt2A8j8g/XSdZg5m3bYI/AAAAAAAADD0/lFl44QB1u2Ihi5obncebKpf6qDBb0o7HgCLcBGAs/s640/school%2Bhotspots%2BPH.jpg" width="492" /></a></div>
<div>
<br /></div>
<div>
It's interesting to see the proliferation of schools being built beyond the greater manila area and central Luzon. It was however a question to me on why do we have cold spots in Ilocos and Cagayan region? Access or topography might be a factor but it's worth another spatial analysis.</div>
<div>
<br /></div>
<div>
Panay region is quite a surprise instead of the province of Cebu being generated as hot spot.</div>
<div>
<br /></div>
<div>
Davao in Mindanao is a given. Marawi is also a given cold spot.</div>
<div>
<br /></div>
<div>
Mapping is addicting. The more you map, the more you want to dig deeper into a phenomena.</div>
</div>
<div>
<br /></div>
<div>
I have generated another interesting map on outlier analytics of such generated hot spots. Will feature it in my succeeding posts.</div>

Last December 2018, we got our Korean Visa approved. We are a family of five with our three kids aged 12, 11 and 5. It's our 3rd country together. We have travelled to Hong Kong and Taiwan before our application for Korean Visa. I have a US Visa, I've been to 11 countries and husband has been to 8 countries before our application. Our frequent traveller status must have contributed to our easy approval.</div>

<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
I have read lots of horror stories on Korean Visa application so I made sure all the requirements are done. Korean Visa has more tedious requirements than Japan Visa.</div>

<li>Bank Certificate - should be with Average Daily Balance aside from current balance. Based on my previous researches, ADB should be atleast 30,000 pesos per person but no, our total ADB is just around 60,000 pesos for all of us 5. </li>
<li>Bank Statement - should be atleast 10,000 per person per day of travel. So for our family of 5 staying for 4 days in Korea, the sum of deposit in our bank accounts should be atleast 200,000 pesos</li>
<li>passport size ID pictures - we just took our own pictures at home and printed it in photo paper. Should be white background</li>

Got our Single Entry Japan Visa and I am so happy that everything went well. Thought I might share how we got our JAPAN VISA for our family with 3 kids and only me as the guarantor. I applied March 29, 2019.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
<br /></div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
So we decided to go to Japan for our next travel destination with the kids. We've been to Hong Kong, Taiwan and Korea before this.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
<br /></div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
Here's our case, we are a family of five (5) with me and my husband as full-time employed and our kids are aged 12, 11 and 5 years old at the time of application.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
<br /></div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
We sent our application through Reli Tours. Reason is because most of my friends have tried it and all of them got approved. Some even tried Friendship Tours at Dusit Thani and they also got approved. I think primary reason why it's best to apply at Reli because of the price and proximity to us. Reli is just 950 pesos each while other agencies can go as high as 1600+ pesos.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
<br /></div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
Anyway, I made sure I submitted all required documents and added some supporting documents to justify economic ties in the country.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
<br /></div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
here are my tips in case it might help your next family trip to japan.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">
</div>
<ol style="margin-bottom: 0px; margin-top: 0px;">
<li>Submit authentic documents. </li>
<li>Follow all the instructions in the japanese embassy website</li>
<li>Ask for help/assistance at your travel agency of choice. </li>
<li> Rule of thumb on bank certificate is to have atleast 10,000 pesos per day per person. So like for us, we are five(5) and traveling for 4 days, the sum of our bank certificates should be atleast 200,000 pesos. Bank certificates should be valid for 3 months and you may submit bank certificates from all your banks.</li>
<li>I did not reserve any hotel but just copied a hotel address in Osaka from Agoda</li>
<li>I have submitted the following supporting docs</li>
<ul style="margin-bottom: 0px; margin-top: 0px;">
<li>ITR (BIR Form 2316) of my husband</li>
<li>Certificate of employment of husband and mine</li>
<li>Booking confirmation of our flight via Jetstar</li>
</ul>
<li>As mentioned, I am the guarantor for the whole family so I have submitted a guarantee letter.</li>

Important Notes from model above:<br />
<br />
GENERATING THE STREAM RASTER:<br />
<br />
To generate the Output Raster or the STREAM RASTER, use Raster Calculator CON tool and enter the expression below:<br />
<br />
<i>Con("FlowAcc_Flow1" > 100, 1)</i><br />
<i><br /></i>
The number '100' states how many cells drains toward the stream network. This can be varied depending on the detail of stream network needed for modeling. The smaller the area, the smaller the number to be entered.<br />
<i><br /></i>
GENERATING POUR POINTS<br />
<br />
In generating the watershed, pour point location is needed.<br />
To automatically generate pour points, use Stream to Feature > Feature Vertices to Points.<br />
<br />
(Note however that Feature Vertices to Points is only available for ArcGIS Advanced license (formerly ArcInfo.)<br />

<dd style="margin: 0px;">Anyone can prepare the document, however, the deed of sale must be ratified before the notary public and it is common for him to draft it and conduct the whole process on behalf of the parties. The buyer may opt to furnish his own deed of absolute sale or may have the form packaged with the notary public for an additional fee. A sample format can be found <a href="http://legal-forms.philsite.net/deed-of-sale.htm" rel="nofollow" style="background-color: rgba(0, 0, 0, 0); background-position: initial initial; background-repeat: initial initial; color: #0b5eb4; margin: 0px; outline: none; padding: 0px; text-decoration: none;" target="_blank">here. </a></dd></dl>

The Revenue District Office(RDO) is the BIR Office for the lot's assigned revenue district. List of accredited banks is posted at your respective RDO. Assessors within the RDO will provide you with a form indicating the total amount and the break down of all your payables to be paid at one of the RDO's affiliate banks. This is done within 5 days after the close of the month when the taxable document was signed or within 30 days after the sale, whichever is earlier. The taxes are paid at the authorized bank to the account of the Bureau of Internal Revenue. The Capital Gains Tax is 6% of capital gains based on selling price, fair market value or zonal value, whichever is higher.<br />The Documentary Stamp Tax is 1.5% based on selling price or fair market value, whichever is higher.<br /><br />The documentation shall include:<br />- Original copy and photocopy of notarized deed of sale of building (obtained in Procedure 1)<br />- Certified true copy of transfer certificate of title (in the name of seller)- Certified true copies are obtained at the Registry of Deeds where the lot was registered/located. A fee will be tendered for the certification and usual procedure takes 3 days to complete. "Rush" certifications with additional fee( bribe! ) will enable you to get it within the day.<br />- Certified true copy of latest tax declaration (in the name of seller) (obtained in Procedure 2)<br />- Photocopy of the latest realty tax receipt.</dd><dd style="margin: 0px;">- Letter of request for certificate of authority to register.<br />- Identification card of the person requesting.</dd>

The Entry clerk receives and enters all documents in the primary Entry Book (Judicial form No. 39) and notes therein the day, hour and minute of reception of all instrument in the order in which they are received.<br />2. Documents are then brought to the Registrar of Deeds (RD) or Deputy Register of Deeds for assignment.<br />3. Documents/Titles are assigned by the RD to the Land Registration Examiner (LRE) who prepares computation and order of payment of registration fees.<br />4. Pay registration fee to the cashier, who shall issue official receipt. Fixed fees are computed based on a schedule of Fees approved by the Department of Justice.<br />5. Upon the payment of the fees, the document is forwarded to the LRE who reviews the same and determines whether or not it is ready to register. The owner’s copy of the title is compared to the title on file, produced by Records Officer/Vault keeper.<br />6. If the instrument is not ready to be registered, the LRE recommends its denial to the RD. If the instrument is ready, the LRE likewise recommends to the RD the registration of the document through a routing slip.<br />7. RD reviews examination, and once same is approved, assigns documents to clerk for action, with instruction on the route slip.<br />8. If the transaction involves issuance of title, Records Officer/Judicial Form Custodian records the transaction in the logbook releases sets of title forms (judicial form) and assigns the corresponding title control number to the set of titles issued to the action clerk.<br />9. Assigned employee acts on the documents, as instructed.<br />10. Final registration – RD signs titles and documents.<br />11. Release of documents – by the releasing clerk to the buyer who should be ready with ID and copies of official receipts of the registration fees.<br /><br />The documentation shall include:<br />- Articles of incorporation and by-laws of the buyer<br />- Secretary’s certificate containing the resolution of the board of directors of buyer approving the sale<br />- Original copy of owner’s duplicate of the transfer certificate of title (in the name of seller)<br />- Certificate authorizing registration from the Bureau of Internal Revenue (obtained in Procedure 4)<br />- Realty tax clearance from the Treasurer’s Office ( obtained in Procedure 5)<br />- Official receipt of transfer tax payment (obtained in Procedure 6)<br />- Official receipts of the Bureau of Internal Revenue (for capital gains tax and documentary stamp tax) (obtained in Procedure 3)</dd></dl>

This is the very typical example why the people in our country should free our data!</div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-kW0wfwWyhYo/T5axDG4P0jI/AAAAAAAAB6M/Kq9CNq2Crac/s1600/osm+vs+mmdata.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="362" src="http://1.bp.blogspot.com/-kW0wfwWyhYo/T5axDG4P0jI/AAAAAAAAB6M/Kq9CNq2Crac/s640/osm+vs+mmdata.jpg" width="640" /></a></div>
<br />
Shown above is a map of my road data for a hydrologic model. Two unaligned road networks are visible from the image above. The red lines are my initial datasets which are actually "PAID" dataset from a government agency. <b>When I did an overlay with a pan-sharpened satellite image, I got a large shift from the actual road network visible in the image itself. </b>My initial notion is to georeference the image so that it would fit the readily available road data. However, when I tried overlaying the location of my mapped inlets, I noticed that the storm drain network which is aligned with the road coincides with that of my backdrop image. These inlet locations are in-situ observations gathered from a week of fieldwork hence there must've been a BIG problem with my road dataset. My next solution is to look for a free dataset. I have tried using <a href="http://gisgpsgeodesy.blogspot.com/2011/04/free-road-data-shapefiles-for.html" target="_blank">Open Street Map data</a> and alas! <b>OSM data has a better fit!</b> The yellow road network above which tends to coincide with the blue network of dots is actually the road data from Open Street Map. See how great and more reliable those FREE and OPEN datasets are?<br />
<br />
Of course there may be some risks in using these free datasets but for my purpose, the OSM data obviously provides a better accuracy as compared to the "PAID" datasets that we get which are highly erroneous and on the first place.. shouldn't be PRICED at all!<br />
<br />
I think our government should somehow consider this example. There's no harm really in opening our data to the public, the limitations should by far be set properly though.<br />
<br />
With free and open data we get a WIDER COMMUNITY to do the refining for us. The blunders are fixed through time and we get something that's FREE and USEFUL and MORE RELIABLE for our ancillary datasets that would soon build a a more seamless layer overlay and analysis in our own geographic information system.MELhttp://www.blogger.com/profile/00621806111928416045noreply@blogger.com1tag:blogger.com,1999:blog-4701621851459914933.post-81429106118102102042012-04-23T23:48:00.001-07:002012-04-24T00:11:45.482-07:00How to choose a course for college and get a career after graduation<div class="separator" style="clear: both; text-align: center;">

<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;">A few weeks ago, I was asked to give a short talk to a few young people about some wisdom on choosing their college course or future career. Since I haven't gone into the industry and had much of my time spent on research, I preferred taking the college course guidance part and leaving the industry and career after graduation part to my husband who has gone farther than me in terms of employment and experience of course. </span><br />
<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><br /></span><br />
<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;">So for me, I made this analogy:</span><b style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><span style="font-size: large;"> Choosing your college course is almost the same as choosing your next faithful pair of shoes!</span></b><br />
<ol>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>Your choice of shoes should fit your budget and so is your choice of college course.</b> - Have a reality check. You might be wanting the most expensive shoes and yet you know you can't afford it just yet. You may try your way by working harder while studying to earn your dream degree and yet end up not finishing it because of deeper financial constraints. So you better be real earlier or end up in regret of an unfinished dream.</span></li>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>You will be the one to wear it so you yourself should love it.</b> - Be passion driven. Know what you love doing the most and start from there. Your hobby may not necessarily bring you more money but later on in life, when you get to choose your respective jobs, you wouldn't want to get burned out because of a job that pushes you to death simply because you don't find enjoyment in doing it but you just want to earn big bucks for it. Mind you, loosing a job is more bearable than loosing your smile. </span></li>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>You will invest money, time and effort and choosing it so you better get the best pair that will fit your needs.</b> - What are your priorities in choosing a course or career? Do you want to earn more money or do you want to improve your skills and doesn't really care if you earn or not afterwards? You set your standards and choose the course that will best fit such yardsticks. Choosing an inexpensive career from a vocational school on being a "barista/ bar tender" and then getting into a well-known hotel or cafe is more rewarding than finishing an expensive nursing degree ending up as a call-center agent after graduation. </span><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"> </span></li>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>You will use it for long so it must be sturdy and can withstand the test of time</b>. <b>Make sure you buy a tried and tested brand</b>- Do your homework and research for the best institution offering your career of choice. The school may not be the real determinant of your success but it will surely pave you the way. Just as you may be needing or learning far more than what you've learned from the four corners of your classroom when you get into the industry, graduates from the best schools always have their edge.</span></li>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>You wouldn't want to have so many other people wearing the same shoes as yours.</b> - Don't take a course just because it's IN. Four or five years from now, that employment boom today may no longer be that in-demand as it is. You wouldn't want to compete with others in terms of employment afterwards or worse, you wouldn't want to be underemployed afterwards and not having the chance to practice your honed skills simply because there are no enough jobs for all of you graduates of that course. If you can, I fervently hope you will... please don't ride at the BANDWAGON of unemployed/ underemployed after graduation. </span></li>
<li><span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;"><b>When everything else fails and you feel like you ain't got a choice at all, TRUST THAT GOD WILL GIVE YOU THE BEST PAIR! </b>- I have my own gauge of divine intervention. If I got an opportunity smoothly, almost without lifting my fingers, I know it's God's will. Do your best in choosing your career but make sure you keep the balance between all aspects - social, physical, intellectual and<b> spiritual</b> most importantly. I was once a stranger to this Geomatics field. I never even knew such course exist but I knew God placed me in here to make a difference. It's the divine intervention that made me push through and eventually love the field that I am into right now. I would always think that <b>GOD GAVE ME THIS and HE has a plan for me... of that I'm SURE! Of that I'm SURE!</b></span></li>
</ol>
<div>
<span style="font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;">And one last word and I think this is as important as your choice of career. Remember that the moment you get there ...</span><span style="font-size: 7pt; text-indent: -0.25in;"> </span><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #8b8b8b; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">"</span></i></b><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #033d21; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">Whatsoever thy hand findeth to do</span></i></b><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">,<span class="apple-converted-space"> </span></span></i></b><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: maroon; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">do it with thy might.</span></i></b><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #a2a2a2; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">"</span></i></b><span class="apple-converted-space" style="text-indent: -0.25in;"><b><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;"> </span></i></b></span><b style="text-indent: -0.25in;"><i><span style="background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #8b8b8b; font-family: Arial, sans-serif; font-size: 14.5pt; line-height: 115%;">(Ecclesiastes 9:10)</span></i></b></div>

For the past few days, or even weeks, there have been much-a-do-and-say about such "overrated" launch. Most countries, especially the first world, are having debates on such move by NoKor.<br />
<br />
<a href="http://www.reuters.com/article/2012/04/12/us-north-korea-rocket-idUSBRE83B1OR20120412" target="_blank">Reuters</a> reports:<br />
<blockquote class="tr_bq">"North Korea<span style="background-color: white; font-family: arial, helvetica, sans; font-size: 14px; line-height: 22px;"> said it wanted the Unha-3 rocket to put a weather satellite into orbit, although critics believed it was designed to enhance its capacity to design a ballistic missile to deliver a nuclear warhead capable of hitting the continental United States."</span></blockquote>So, is that it? Is North Korea already that powerful to wage war against those first world countries?<br />
<br />
The paranoia has reached countries within the flight-path of such North Korean rocket including the Philippines. And since we are not capable of shooting such debris from the sky, removing it from its trajectory and totally crashing the rocket parts as it enters the Philippine area of responsibility, we were just advised to refrain from going out on some specific time of the day when the rocket would supposedly pass by our country. What do you think? <br />
<br />
I would often wonder how the people could've reacted to the<a href="http://www.spacedaily.com/news/japan-h2a-03a.html" target="_blank"> Japan's launch of Spy satellites in 2003</a>? Or how about the <a href="http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/980202e.html" target="_blank">4000++ satellites launched since 1998</a>?<br />
<br />
<a href="http://www.wisegeek.com/how-many-satellites-are-orbiting-the-earth.htm" target="_blank">Wisegeek </a>also says:<br />
<blockquote class="tr_bq"><span style="background-color: white; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; text-align: justify;"> "There are approximately 3,000 satellites operating in Earth orbit, according to the US National </span>Aeronautics<span style="background-color: white; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; text-align: justify;"> and Space Administration (</span><a href="http://www.wisegeek.com/what-is-nasa.htm" style="background-color: white; color: #24364f; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; outline-color: initial; outline-style: none; outline-width: initial; text-align: justify;">NASA</a><span style="background-color: white; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; text-align: justify;">), out of roughly 8,000 man-made objects in total. In its entire history, the SSN has tracked more than 24,500 space objects orbiting Earth. The majority of these have fallen into unstable orbits and incinerated during reentry. The SSN also keeps track which piece of space junk belongs to which country.</span></blockquote><blockquote class="tr_bq"><span style="background-color: white; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; text-align: justify;">As of 2008, the former Soviet Union and Russia had nearly 1,400 satellites in orbit, the USA about 1,000, Japan more than 100, China about 80, France over 40, India more than 30, Germany almost 30, the UK and Canada 25, and at least ten each from Italy, Australia, Indonesia, Brazil, Sweden, Luxembourg, Argentina, Saudi Arabia, and South Korea. </span><span style="background-color: white; font-family: 'Droid Sans', Arial, sans-serif; font-size: 14px; line-height: 18px; text-align: justify;">"</span></blockquote><a href="http://spacenews.com/launch/110826-forecast-rise-sat-launches.html" target="_blank">Spacenews</a> even reported some 10 year forecast that:<br />
<blockquote class="tr_bq"><span style="background-color: white; font-family: Arial, Verdana, sans-serif; font-size: 14px; text-align: left;">"According to the annual forecast of global launch activity the consulting firm released Aug. 25, an estimated 1,145 satellites — worth $196 billion worldwide — will be built between 2011 and 2020. About 70 percent of the satellites can be attributed to government demand, Euroconsult said."</span></blockquote>Those satellites, just like that of South Korea, were of course rocket launched. But why make an argument on a single-failed attempt to stop a satellite launch just now? Just so it may have been disguised as a ballistic missile test? But what about those countries who have just launched their own rockets some few years back?Why make much a fuss about a weather satellite from a relatively newcomer in the space-technology-era?<br />
<br />
Since retrieving a broken satellite from space is more expensive than launching it, the satellite-space junk is continuously increasing through time thus creating a SPACE POLLUTION so to speak. Just as there are already a number of operational and non-operational satellites and space debris on the earth's orbit, these seemingly-fictional space junk image must've been really turning into a reality.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-dbs1nBxqdg8/T4eddFHdsSI/AAAAAAAAB5E/Ug5TIFELCXs/s1600/Downloads.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://1.bp.blogspot.com/-dbs1nBxqdg8/T4eddFHdsSI/AAAAAAAAB5E/Ug5TIFELCXs/s400/Downloads.jpg" width="400" /></a></div><br />
Just as our sky's NO LONGER the limit anymore and there are already thousands and tons of space junks already in orbit on our precious mother earth, why trouble ourselves much with the worry of a fail attempt to launch a "weather" satellite JUST NOW? Maybe the delayed reactions are already too late, or maybe too, it may just be in time.<br />

That was about 371 hectare area of land with a mix of residential, commercial and industrial land uses. I have used 2 types of Garmin Handheld receivers for this part, the Garmin Oregon 550 and the Garmin 76CSx for this storm drain inventory and mapping field work.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-sq4kDwZwqJI/T3lRkwVWAfI/AAAAAAAAB4k/HDbVNVz0dPs/s1600/gps.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="http://2.bp.blogspot.com/-sq4kDwZwqJI/T3lRkwVWAfI/AAAAAAAAB4k/HDbVNVz0dPs/s640/gps.jpg" width="640" /></a></div><br />
I would say that both are pretty good in terms of accuracy for a handheld receivers with a purpose of mapping features just for reconnaissance or coarse accuracy requirements. Here are my <strike>rants/raves</strike> two cents for fieldworks utilizing handheld GPS receivers i.e. GARMIN GPSmap 76CSx and Oregon 550.<br />
<ul><li><b>Do understand the primary purpose or objective of your data gathering and use the right tool for such purpose.</b>- You can't use a handheld GPS receiver to plot the corners of your lot and use it as an evidence for a land grabbing case. Have a clear understanding of the capabilities of the GPS device that you are using. The handheld GPS are of the lower accuracy type with an accuracy buffer of 10-30m so if you are, for example, trying to map all the trees within the neighborhood or for my purpose map all the storm drains to locate inlet locations for my flood simulation, the accuracy of a handheld receiver is already sufficient. </li>
<li><b>Use Alkaline batteries if rechargeable NiMH batteries are not available. </b>- As you may know, GPS devices are power hogs. This is the major reason why your iPhone drains faster than usual when your location services that utilizes GPS are turned ON. So for your purpose of mapping, if you've got one large area to cover, better make sure you have lots of spare batteries at hand. Based on my experience, the Alkaline batteries (Energizer) lasted for 8 straight hours for the Garmin GPSmap 76Csx while it only lasted for almost 4 hours for Oregon 550. The longer performance of the 76CSx would be understandable since it doesn't have a camera that uses up much power unlike that of the Oregon 550. On my first day, I have used Eveready but to my dismay, it only lasted for 2 straight hours of mapping so I have to readily change batteries which is very much of a hassle. NiMH are also good choices for it lasts about 5 hours for the Oregon 550 but you still have to bring spares for longer mapping works.</li>
<li><b>Make sure to immediately save all your data gathered when you come back at the office. </b>- This is my HARDLY LEARNED lesson . I have tried Oregon 550 first and since it has a support for memoru expansion, I didn't have worries for memory shortage. To my dismay, the GARMIN 76CSx can only save up to 1000 waypoints. I am an hour before my last 3 kilometer stretch for the week-long fieldwork and I already ran out of waypoint memory. Too bad, I can't delete the previously gathered points :(. So unless you have a laptop onfield to readily save your data, better make sure to have it backed-up and deleted on the GPS receiver memory to allot more space for your recent observation points. For me, I have installed the MapSource program to receive and upload data from my computer to the GPS device. It has an option to save your data in GARMIN database, GPX (GPS exchange format), and TXT format for further processing :)</li>
<li><b>Plan your route ahead. </b>There is indeed no better substitute to a carefully planned fieldwork. It would definitely save you much of your resources- time, money and effort. Just as there may be slight deviations from the original plan, plannning ahead is still the best way to commence every field data gathering exercise.</li>
<li><b>Lastly and Again know your device before going on field! - </b>Part of the carefully planned fieldwork is a thorough knowledge on operating the device that you are going to use. Familiarity is the key. For user-friendliness, I like the Oregon 550 more because it's already in touch-screen interface as compared to the 76CSx which is still operated by button.<b> I never really had a hard time getting used to Oregon 550 but the 76CSx is a whole new different story. </b>I don't know if it's just me and my stupid nature that took me an ample 2 hours to figure out how to mark waypoints using the GARMIN 76CSx. So for the record, <b>HOW TO MARK A WAYPOINT USING GARMIN 76CSx, Just long press the ENTER button and there you have it! (^_^) </b>The deleting of waypoints and tracks are also harder ones or I guess less intuitively designed ones. You can figure it out by pressing the menus over and over again. So yeah, FAMILIARITY IS THE KEY! So don't hesitate to explore your devices first or you'll have the entire day out on field exploring on how to use it...</li>
<li>Oh no, beforeI forget...In case you ran out of space for waypoints in your Handheld GPS and you still got a phone powered by GPS (that's not yet on a low battery!) ... you may opt to use it for mapping purposes too! I seemed to have been really frustrated when I ran out of waypoint memory and forgot to use my HTC Mozart which is also capable of geotagging photos. So yeah, for my next field mapping work, I would be very much reminded of using my usual buddy for my location-based needs:) Since our modern smartphones nowadays are already GPS powered, it works pretty much like our handheld receivers with Assisted GPS (AGPS) capability. This AGPS utilizes the location of the nearest cellsite to easily "assist" fix your position. Very nice indeed. This is a photo taken from my fieldwork for which I have turned on the location option everytime I take photos. When I tried geotagging it in Picasa, it appeared to be about 10m off the original location as specified by the Handheld GPS which is fairly ok for mapping purposes. </li>

</div><div>Just are there are no fast rules, I hope this helps and I'm sure I'm getting more of these hardly-learned lessons that I will gladly share and chronicle here in my blog in the days to come...just so until I'm done with my data gathering part of my thesis #fieldworkIsMoreFun (^_^)</div>MELhttp://www.blogger.com/profile/00621806111928416045noreply@blogger.com0tag:blogger.com,1999:blog-4701621851459914933.post-49260961563688534672012-03-08T22:15:00.000-08:002012-03-08T22:15:40.340-08:00Back-sighting the history of SurveyingLast November 28- December 2, 2011, I had the chance to participate in a course for GPS data analysis and modelling (GDAM) for scientific and practical application workshop held at the National Engineering Center of UP Diliman.<div><br />
</div><div>Part of the itinerary is a day of field trip to the major research agencies that uses Global Positioning Systems (GPS) in the modelling and analysis of crustal movements for their respective scientific applications.</div><div><br />
</div><div>The agencies that we have visited are the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Manila Observatory and the National Mapping and Resource Information Authority (NAMRIA).</div><div><br />
</div><div>At PHIVOLCS we get a peek on how the GPS data from continuous and campaign sites have been archived, processed and delivered. These data will then be used further for the analysis of crustal movements specifically along the Philippune Fault as well as the deformation and movements on active volcanoes in the Philippines such as Mayon and Kanlaon. Having been part of the PHIVOLCS-GPS Team for quite some time, I am already familiar with the processing scheme using Bernese 5.0 which is Windows-based. In this workshop however, we are taught on how to process and model GPS data using GAMIT-GLOBK and DEFNODE respectively. GAMIT-GLOBK and DEFNODE both runs in LINUX. </div><div><br />
</div><div>Another office that we have visited is the Manila Observatory where an IGS station -PIMO is located.</div><div>A short introductory GPS presentation was given during our visit.</div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-Fa5B9XKMGMY/T1mRfz_vfwI/AAAAAAAABss/1uhQQqnLBN4/s1600/WP_003552.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="90" src="http://1.bp.blogspot.com/-Fa5B9XKMGMY/T1mRfz_vfwI/AAAAAAAABss/1uhQQqnLBN4/s320/WP_003552.jpg" width="320" /></a></div><br />

Of course we also got sight of the only International GPS Service (IGS) station in the Philippines for the longest time since 1980's I guess. That is PIMO appearing in the photo below. I think NAMRIA has recently added another IGS station, PTAG which is located at their office in Taguig. So in total, there are already 2 IGS stations that's tied into the International Terrestrial Reference Frame (ITRF) in the Philippines to account for the movement of our 7107 islands that's being tectonically active and bounded by four major tectoic plates.<br />

<div class="separator" style="clear: both; text-align: center;"></div> After the Manila Observatory, our next stop is NAMRIA where the Data processing and archiving of the Philippine Active Geodetic Network (PAGEnet) takes place.<br />
<br />

<br />
After the lecture and introduction of the data monitoring procedures done in the PAGEnet Data and Control Center, we got the chance to tour around the museum located at ground floor of NAMRIA. The surveying instruments of the past were carefully preserved and displayed within the room.<br />

Win up to $1M by hacking Google Chrome!<span style="font-family: 'Trebuchet MS', sans-serif;">It was of great awe that I discover this morning how Google Chrome developers have just been so confident of the security of their product that they really got some pretty great awards for those who could break in their security.</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;"><br />
</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;">Hack Chrome! Get Rewards! Nice nice!</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;"><br />
</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;">This year again CanSecWest is offering up to ONE MILLION DOLLAR reward for geeks who could crack the Google Chrome codes and bring themselves to the pedestal of their dreams. Yeah, who knows? It might just be another entrepot for such hidden talents that really ought to be brought out of the </span><strike style="font-family: 'Trebuchet MS', sans-serif;">underground</strike><span style="font-family: 'Trebuchet MS', sans-serif;"> dark.</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;"><br />
</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;">So here are the compelling prizes to drool so much about:</span><br />
<blockquote><span style="font-family: 'Trebuchet MS', sans-serif;"><b>$60,000 -</b> “Full Chrome exploit”: Chrome / Win7 local OS user account persistence using only bugs in Chrome itself. </span></blockquote><blockquote><span style="font-family: 'Trebuchet MS', sans-serif;"><b>$40,000 -</b> “Partial Chrome exploit”: Chrome / Win7 local OS user account persistence using at least one bug in Chrome itself, plus other bugs. For example, a WebKit bug combined with a Windows sandbox bug.</span><br />
<span style="font-family: 'Trebuchet MS', sans-serif;"><b>$20,000 -</b> “Consolation reward, Flash / Windows / other”: Chrome / Win7 local OS user account persistence that does not use bugs in Chrome. For example, bugs in one or more of Flash, Windows or a driver. These exploits are not specific to Chrome and will be a threat to users of any web browser. Although not specifically Chrome’s issue, we’ve decided to offer consolation prizes because these findings still help us toward our mission of making the entire web safer. </span></blockquote><blockquote><b><span style="font-family: 'Trebuchet MS', sans-serif;">All winners will also receive a Chromebook.</span></b></blockquote><blockquote class="tr_bq"><b><span style="font-family: 'Trebuchet MS', sans-serif;">They will issue multiple rewards per category, up to the $1 million limit, on a first-come-first served basis. There is no splitting of winnings or “winner takes all.” They require each set of exploit bugs to be reliable, fully functional end to end, disjoint, of critical impact, present in the latest versions and genuinely “0-day,” i.e. not known to us or previously shared with third parties. Contestant’s exploits must be submitted to and judged by Google before being submitted anywhere else. </span></b></blockquote><span style="font-family: 'Trebuchet MS', sans-serif; line-height: 15px;">Yey! The bribe is not that bad, so you playful geeks could now start the ball rolling! May fickle fate find you fierce fellows! (^_^)</span><br />

<br />
GIS tools and ArcGIS mapping applications play an important role in developing data-driven solutions that help health organizations visualize, analyze, interpret and present complex geo-location data.<br />
<br />
The World Health Organization maintains an updated influenza map that shows Asia and Africa are at greater risk the spread of flu. Other organizations such as Health-mapping.com keep up-to-the-minute data-filled maps that cover water and health, influenza and malaria.<br />
<br />
One map keeps water-related infectious diseases in the WHO European Region, focusing on the visualization of pan-European and worldwide water-related disease data that comes from centralized information system for infectious diseases (CISID) database. The map covers HIV/AIDS, sexually transmitted diseases, Tuberculosis, Diphtheria and several other diseases.<br />
<br />
Then there’s HealthMap.org, which was founded in 2006 to use online sources to help with disease outbreak monitoring.<br />
<br />
Created by epidemiologists and software developers at Children’s Hospital Boston, the freely available website and mobile app ‘Outbreaks Near Me’ deliver real-time intelligence on a broad range of emerging infectious diseases for a diverse audience including libraries, local health departments, governments and international travelers.<br />
<br />
HealthMap brings together disparate data sources, including online news aggregators, eyewitness reports, expert-curated discussions and validated official reports, to achieve a unified and comprehensive view of the current global state of infectious diseases and their effect on human and animal health.<br />
<br />
Through an automated process, updating 24/7/365, the system monitors, organizes, integrates, filters, visualizes and disseminates online information about emerging diseases in nine languages, facilitating early detection of global public health threats.<br />
<br />
For example, HealthMap.org recently released a report that several Massachusetts swans tested positive for low-path avian influenza or bird flu. Although the report indicated there is no threat to human health, this latest finding is just an example of how GIS can help save lives in the case of an outbreak.<br />
<br />
“The real focus is identifying and focusing surveillance in hotspots around the world where we have potential for risk of a new disease that potentially might cause a pandemic worldwide,” said John Brownstein, co-founder of HealthMap.org and assistant professor of pediatrics at Harvard Medical School.<br />
<br />
Maps are also tracking obesity and diabetes. CDC data and mapping indicates 644 counties in 15 states represent most of the country’s type two diabetes cases. This has been called the “Diabetes Belt,” which spans from Appalachia into the Deep South. Data also shows that a few counties in Michigan also have higher rates, as well as some regions in the West.<br />
<br />
Meanwhile, Esri, an international geographic technology firm whose software is used by more than 350,000 organizations worldwide, has a GIS for Health & Human Services division that helps public health organizations and hospitals alike. Hospitals use ArcGIS for accurate and relevant patient information as well as for marketing, planning and community relations.<br />
<br />
For example, the University of Kentucky Trauma Center, called UK Chandler Hospital used a customized GIS application to boost analyze data.<br />
<br />
“We built the custom ArcGIS Server application using the Flex API to maximize accessibility and ease of use,” said Chris Walls, cofounder of 39°N, the firm that built the platform for UK. “We are extremely proud of this cutting-edge collaboration with the University of Kentucky. This kind of application will significantly streamline the administration of public facilities.”<br />
<br />
GIS technology and ArcGIS offers tremendous potential to benefit the health care industry and its many uses are just now beginning to be realized. The need for GIS professionals who are proficient using ArcGIS will be even greater as organizations develop innovative ways to harness the data integration and spatial visualization power of GIS.<br />
<br />
“The philosophy of American Sentinel’s bachelor’s in GIS curriculum is to prepare students for real workplace issues and challenges using state-of-the-art, industry leading software products such as Esri’s ArcGIS and open source technologies,” says Devon Cancilla, Ph.D., dean, business and technology at American Sentinel University.<br />
<br />
Dr. Cancilla believes it’s important to empower students with a current and applicable GIS skill set such as using ArcGIS, so students can apply relevant knowledge on the job while use real-improving their career trajectory.<br />

<br />
The usual discretization is performed on my data, I scraped out all the noisy points by limiting my range to 5cm o 100m. Now I added another criterion, that is to remove all points below my LIDAR setup. That is to consider theta(horizontal FOV)<90 and theta >270 degrees. That in a way reduced my point cloud into almost 30% of the original. Memory-wise, it was a LUXURY already!<br />
<br />
Now for checking the irregularities in the observed point cloud, using the Point File Information Tool is by far the best solution. Using ArcGIS 10.0:<br />
<br />
1. Go to 3D analayst tools>Conversion>From File> Point File Information.<br />
2. You will be opt to browse lidar point cloud by File or by Folder. (I suggest that you browse by Folder if you've got more than 10 files.)<br />
3. Now you will be opt for the file format. Since what I did is to manually derive the point cloud from scratch and most of my intensity returns are not so usable due to our observation time at night, I opted using XYZ format instead. The binary LAS format is the mainstream interchange format which is optimized and I guess what's available from available vendors out there. Anyways..<br />
4. Specify the suffix (file extension) and Coordinate System in case you have any.<br />
<br />
Now I have tested using just the first 200 rotations for checking my point file information.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-9jmO5AT2b14/TyYwn4ourPI/AAAAAAAABmc/K7mlbAhjjhQ/s1600/point+file+information.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="356" src="http://1.bp.blogspot.com/-9jmO5AT2b14/TyYwn4ourPI/AAAAAAAABmc/K7mlbAhjjhQ/s640/point+file+information.jpg" width="640" /></a></div><br />
What the process will give you are the bounding rectangle, the attribute table and the average point spacing contained within one of the attributes. This average point spacing is crucial when you are to load and visualize the point cloud later.<br />
<br />
So right clicking the Pt_Spacing field in the attribute table, check the statistics to get the average (MEAN) point spacing.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-I_SnPCoVbH4/TyYxvIjJHdI/AAAAAAAABmk/7XehxAcPocs/s1600/stats.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="358" src="http://1.bp.blogspot.com/-I_SnPCoVbH4/TyYxvIjJHdI/AAAAAAAABmk/7XehxAcPocs/s640/stats.jpg" width="640" /></a></div><br />
Now you get to clean your data by looking at the average point spacing, any file that goes too large or too small may be erroneous due to incorrect sampling hence can already be deleted. It's also wise to check on the bounding rectangles to check for inconsistencies.<br />
<br />
Next will be the loading of the LIDAR data.<br />
<br />
My experience is on the ASCII format xyz data. Here are the steps.<br />
1. > 3D Analyst Tools>Conversion>Ascii 3D to feature class. (Input average point spacing as specified in the Point File Information results. Specify coordinate system, input file format etc. if there's any)<br />
2. To create a DEM out of your Multipoints, just use >Conversion Tools>To Raster>Points to Raster<br />
- For the Value Field, use Shape.Z<br />
- For the cell assignment type, use MEAN<br />
- For the cellsize, use average point spacing *4<br />
3. Export data to GRID or Tif to make your data permanent.<br />
<br />
Ok. so now, for my next problem, I found out that my latitude and longitude are being interchanged in plotting. This is quite easy to solve in Matlab through:<br />
<br />
<span style="font-family: 'Courier New', Courier, monospace;">M(:,[1, 2, 3])=M(:,[2, 1, 3]);</span><br />
<span style="font-family: 'Courier New', Courier, monospace;"><br />
</span><br />
<span style="font-family: inherit;">The matrix M contains columns 1,2,3 as lat,long,ht respectively, what I did is to interchange the columns to plot my cloud of points seamlessly in ArcGIS(ArcMap and ArcScene). Nice results so far.</span><br />
<br />
Here's my sample 200 rotations, meaning 20 second Velodyne LIDAR data. The red triangles are points observed through GPS as traversed by the lidar.<br />

<span style="font-family: inherit;">Now my next step is to test the data in a larger scale, I mean for my entire dataset. Let's see what kind of problem will arise next...</span>MELhttp://www.blogger.com/profile/00621806111928416045noreply@blogger.com0
