PostGIS - http://postgis.refractions.net
Refractions Research is pleased to announce the 0.7
release of PostGIS : Geographic Objects for PostgreSQL.
PostGIS/PostgreSQL is a spatial database much like
ESRI's SDE and Oracle's OracleSpatial. PostGIS is
open-source software licenced under the GNU LGPL.
PostGIS/PostgreSQL includes the following functionality:
- Simple Features as defined by the OpenGIS
Consortium (OGC)
- Support for Well-Known Text and Well-Known Binary
representations of GIS objects
- Fast spatial indexing using GiST
- Geospatial analysis functions
- PostgreSQL JDBC extension objects corresponding
to the geometries
- Support for OGC access functions as defined by the
Simple Features Specification
- Accessible from UMN Mapserver version 3.5
(http://mapserver.gis.umn.edu)
Changes in 0.7:
- New Things
- support for PostgreSQL 7.2 GiST index API
- transform() function provides coordinate
reprojection using proj4 library
- spatial_ref_sys.sql has a complete set of proj4
definitions for each EPSG coordinate system
- refactoring of source code to separate index support
functions from other functions
- max_distance() function
- distance_spheroid() function
- collect() aggregate function
- xmin(),ymin(),zmin(),xmax(),ymax(),zmax()
- Bug Fixes
- several patches to loader/dumper
- transform() more graceful when grid shifts
are missing
- setsrid() made cachable
