The OpenStreetMap module for Drupal will allow users to interface with the OpenStreetMap project to create an open map of the world.

The module will be aimed at localised sites for specific regions, allowing people to edit data already in the OpenStreetMap database as well as add their own information to the map. Because all of this information will be treated as nodes in Drupal, you will be able to build up a local information site based on the information. With the GeoRSS module or KML module you could redistribute this information to other people interested, or do just about anything else with the information that you can imagine.

The GPX module for Drupal will allow for export of geographically enabled nodes to GPX format. It will probably extend the views module, similar to the way that the RSS Views module works.

GPX is the standard interchange format used for communicating with GPS (Global Positioning System) devices. It can be used for downloading waypoint and track information from your GPS device and also for uploading to it.

The GeoRSS module for Drupal allows for geodata in GeoRSS format to be extracted from nodes in incoming aggregator2 feeds and also adds the correct tags to outgoing RSS feeds from Drupal sites.

The WFS Server module for Drupal will allow geographic information systems (GIS) to query Drupal sites about geodata they are storing and then communicate it back using the Open Geospatial Consortium standard for Web Feature Services.

The KML module for Drupal allows people to access spatially enabled information through the Google Earth interface.
