PostGIS 2.0.0 released

Wednesday, April 4th, 2012

The long-awaited full featured PostGIS 2.0.0 is finally out. Coupled with GEOS 3.3.3 (released a few days before) and GDAL-1.9.0, it brings you the best spatial database system in town, complete with raster analysis and topology modeling support.

Complete announcement, with list of changes,  here.

It’s been an great pleasure to work with the rest of the team on getting this release ready for shipping, drawing a line after over two years of hard work on new features. I’m particularly proud of the persistent topology support, which kept me busy for the most part of 2011, and the raster support of which I wrote the foundations two years before.

I’m also happy to see an healthily growing community around PostGIS: we’ve had two successful pledges, a growing list of contributors and more corporate sponsors.

A special thank goes to Vizzuality for investing in a full-time PostGIS hacker. Their PostGIS-in-the-cloud solution ( is likely the first one putting PostGIS 2.0.0 in production.
