While a lot of satellite data processing and analysis is done with code (Python in these examples), it is often helpful to be able to view and modify data on a map. Geographical Information System (GIS) software provides a convenient way to explore data and make figures. Here, we will use the Quantum GIS (QGIS) program.

Why QGIS?¶
In the world of GIS desktop applications, ArcGIS is a big name. It is used by a lot of public utilities (cities, municipalities, etc) and is taught in many undergraduate courses. It is a great tool.
For the casual researcher, however, there are two main limitations for ArcGIS. First, it requires a license - and unless you’re an employee or student of an institution that springs for such things, you’re own your own to pay the high costs of a license. Second, ArcGIS can only be used on Windows systems - sorry Mac folks, mapping is not for you.
QGIS provides a remedy to both of these issues - it is open source (free!) and it can be used on any operating system. Thus, for researchers, QGIS is an amazing resource.
