As part of the Geo June activity, we've started a website to aggregate the work being done: http://www.geojune.org. We're aiming to provide documentation, demos of the developing modules, tutorials, etc.
To get the ball rolling on more formal documentation of all things geospatial in Drupal, we've started some Drupal books on geojune.org: http://www.geojune.org/documentation. The idea is to collaboratively work on documentation of not only the geo related contrib modules, but also deeper info about GIS and Drupal in general. The module documentation will be adapted to be included as d.o documentation pages; the deeper documentation, demos, examples will remain or be moved for potential permanent status for future development and reference.
Right now there are two upper-level books: One a getting started guide to mapping, the other a guide to geocoding Drupal data and storing geospatial data in Drupal. This division is loosely meant to divide the two types of contrib modules: display/mapping and geocoding/storage related to GIS work in Drupal. It is a suggested division at this point, open for discussion or further subdivision.
The mapping guide is empty right now. We'd love those involved in mapping modules (Openlayers, etc.) to start putting some pages here. The geocoding guide has some placeholder documentation related to the Geo and Geocode module as lifted from the documentation wiki page started here in the Location Mapping group by ultimike. We've started to break out that info into sub pages.
It's all rough right now. We need as many interested people as possible to weigh in and start documenting. Go to the site, get yourself a login, and contribute! Head into the #drupal-geo IRC channel for guidance or to ask maintainers/documenters for potential documentation assignments. We also hope to get a group from the Twin Cities Drupal Users Group Documentation Sprint on June 20 to take parts of this on as a project.
Thanks,
