The 2.1.6 release of PostGIS is now available.
The PostGIS development team is happy to release patch 2.1.6 for PostGIS 2.1. The focus of this release is on bugs and performance issue. Users with large tables of points will achieve large (~50%) disk space savings by upgrading to this patch.
What is PostGIS?
PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS "Simple Features Specification for SQL" and has been certified as compliant with the "Types and Functions" profile.
PostGIS development was started by Refractions Research as a project in open source spatial database technology. PostGIS is released under the GNU General Public License. PostGIS continues to be developed by a group of contributors led by a Project Steering Committee and new features continue to be added.

Rento is a free web service that makes it easy to find a place to rent in Greece. Powered by PostgreSQL and PostGIS, it provides ad listings with photographs displayed on a map. Searching is accomplished through map navigation and natural language processing, with the search engine being capable of answering complex (spatial) questions such as "flat near the University of Athens" or "loft up to 800 euros near a metro station" (in greek).
Building on the local and scientific knowledge of the Pacific Rim Bio-Region, Ecotrust is attempting to increase ecological awareness through the use of GIS and spatially enabled technologies.
