Chapter 8. Working with Spatial Data
In this chapter, we will apply and build on the knowledge that we gained in previous chapters to create a sophisticated web application called DISTAL (Distance-based Identification of Shorelines, Towns, and Lakes). In the process of building this application, we will learn:
How to work with substantial amounts of geospatial data stored in a PostGIS database
How to perform complex spatial database queries
How to make accurate distance-based spatial queries
How to integrate Mapnik into a web application to display results on a map
