[postgis-users] PostGIS 0.9.0 Released

[Paul Ramsey]

Refractions Research is pleased to announce the release of PostGIS
0.9.0, with support for the upcoming PostgreSQL 8.0 release and the 
newly released GEOS 2.0.0 topology library.

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).

Thanks to the work of the PgSQL development team, with PgSQL 8.0 it will 
be possible to use PostGIS under Windows as a native process. Early 
testing of PostGIS on Windows has shown a 30% performance increase for 
the native version over the cygwin version for GIS data loading workloads.

With GEOS 2.0.0, PostGIS now sports robust geometry buffering, and 
improved geometry intersection and union functions. Other PostGIS 0.9.0 
improvements include new management utilities, improved spatial index 
estimation and direct integration in the PgSQL 8.0 statistics gathering 
mechanism.

PostGIS is open source software licensed under the GNU GPL.
