Summary
In this chapter, we finished implementing a sophisticated geospatial web application using GeoDjango, Mapnik, PostGIS, OGR, and pyproj. This application is useful in its own right, as well as being a springboard to developing your own geospatial web applications.
We have learned:
That we can easily create our own Tile Map Server using Mapnik and GeoDjango.
That we can include OpenLayers on our own web pages, independent of GeoDjango, and display map data from our Tile Map Server.
How to create a custom "click handler" to respond to mouse-clicks within an OpenLayers map.
That we can use AJAX calls to have the server respond to events within the web browser.
That GeoDjango provides a powerful query language for performing spatial queries without writing a single line of SQL.
How to "borrow" geometry editing widgets from GeoDjango and use them within your own web application.
That you can create your own
GeoModelAdminsubclass to change the appearance and functionality of GeoDjango's geometry...
