Of coffee and maps

My reading list on GIS has been a bit full so I tried to catch up over the weekend. 
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.

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. 

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.

Now I wonder how the other outlier locations were also an output of the analysis. I must discover it myself...

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.

Free Philippine Administrative Boundaries shapefile

Image
Free Administrative Boundary shapefile can be downloaded here . The coordinate reference system is latitude/longitude and the WGS84 datum. Other file formats such as ESRI geodatabase (.gdb), Google Earth (.kmz), and RData for RProject. Geospatial data from other countries are also available for download here. File Formats A "shapefile" consist of at least three actual files. This is a commonly used format that can be directly used in Arc-anything, DIVA-GIS , and many other programs. Unfortunately, non-latin characters are garbled. An "ESRI geodatabase" is an MS Access fole that can be opened in ArcGIS (an expensive but powerful program). One of its advantages, compared to a shapefile, is that it can store non-latin characters (e.g. Cyrillic and Chinese characters). A "Google Earth .kmz" file can be opened in Google Earth . A "RData" file can be used in R (with the sp package loaded) Some files have been compressed and grouped i

University of the Philippines Diliman Campus

In our GIS class for Geomatics Engineering, we were asked to digitize a pan-sharpened Quickbird image of UP Diliman and specify the roads, buildings, and open spaces in the campus. Also this is my first time to import data from a handheld GPS into my GIS. Here's my output map: We we're also asked to georeference a "very old" aerial photo of UP Diliman campus. Here's the result:
