Summary

In this chapter, we have implemented, tested, and made improvements to a simple web-based application which displays shorelines, towns, and lakes (DISTAL) within a given radius of a starting point. This application was the impetus for exploring a number of important concepts within geospatial application development, including the following:

  • The creation of a simple but complete web-based geospatial application
  • Using databases to store and work with large amounts of geospatial data
  • Using a "black-box" map rendering module to create maps using spatial data selected from a database
  • Examining the issues involved in identifying features based on their true distance rather than using a lat/long approximation
  • Learning how to use spatial joins effectively ...
