I took a group of classes in Geographic Information Systems (GIS) at UCLA. The classes taught me how to find geospatial raster and polygon data on the internet, run custom combinations of standard analysis tools, and create maps showing that information. I also got to dive into some of the Python interfaces used to make and automate those tools.
