After our discussion of geospatial data formats, we walked through two different types of geospatial databases: the PostGIS-enabled PostgreSQL database, as well as the geodatabase provided by Esri.
We concluded the chapter with broad coverage of open source geospatial data on topics of human geography, physical geography, and country- and area-specific data. Given the variety...
