Basically, a Geo-related app should have four modules

  1. a business module deals with all the logic.
  2. GeoDjango can provide data mapping functions like geoIP, distance calculation, zip code searching etc.
  3. OpenStreetMap displays the map.
  4. OpenLayer: a javascript library provides zoom, pan, scroll functions on the web page. It’s an implementation of ‘Slippy Map’. a simple demo, check the ‘Related’ section for further information.
