Chapter 13. Managing a Spatial Database

The previous chapters explained how to interrogate and convert data, and how to select subsets of it for more customized use. This chapter is for those who need a spatial database for creating, managing, and manipulating data. Spatial databases combine the power of a relational database with geographic and tabular information. The focus of this chapter is on getting some spatial data into a database, querying it, and using it in a map. It will also cover how to use PostGIS data in a few different applications and how to export it into other formats.
