Geo Module
The Geo Module looks like a great way to have full GIS support within drupal.
The geo module is the next generation geo-spatial module for Drupal. Like location, it provides storage for points, but it also supports the full range of OpenGIS Simple Features, such as lines and polygons. Geo takes advantage of spatially enabled databases (PostGIS and MySQL Spatial) for native storage, which leads to faster, more informational queries.
Geo is currently is early development, but much of the power of the system is very apparent. Feel free to download the code from CVS, but beware that support will be very limited.
