In this chapter, you learned the necessary background and took steps to get up and running with QGIS. We performed ETL on the location-based data to geospatially integrate it with our GIS project. You learned the fundamental GIS visualization techniques around layer style and labeling. Finally, after some consideration around the nature of basemaps, we produced a tile cache that we could preview in QGIS. In the next chapter, we will use raster analysis to produce an operational layer for interaction within a simple web map application.
