For Colbert fans the “Better Know a District” series is a familiar part of the Colbert Report. Today I’m kicking off my own series “Better Know a GeoCommons Feature.” I’d like you to meet one of our lesser known export formats Spatialite.

For those not familiar with SpatiaLite it is SQLite with spatial function goodness added. GeoCommons exports the geometries from your overlay into Well-known text. To download your Finder overlay as SpatiaLite you can go to a you overlay details page and click the Spatialite Download link or you the URI to access it from the API is http://finder.geocommons.com/overlays/#your_overlay_id#.sqlite. Once downloaded you have functions such as Overlaps(), Touches(), Union() and Buffer().

  4. [...] relational data store that provides great access and compression. About a year ago we even added Spatialite support to GeoCommons – so anyone can convert data to a SQLite [...]

  5. Wow – great work guys, will definitely be having a look at this in conjuction with the work I am doing on Tile5 + mobile :) SpatiaLite would appear to be the *perfect* solution.
