PostGIS: <http://postgis.refractions.net>
PostGIS adds support for geographic objects to the PostgreSQL
object-relational database. For applications with spatial data
management and processing, PostGIS provides all the types, functions,
and indices necessary to get the job done. Add geographical information
systems (GIS) to PostgreSQL with PostGIS.
[2005/12/21] The 1.1.0 release is a major release, including new
functionality, performance improvements and bug fixes. Highlights include:
* Geometry buildings functions, including line merging,
polygon creation and vertex manipulation,
* Linear referencing functions, including support for
measures,
* Performance improvements to coordinate reference transformations,
* Autoconfiguration support, removing the old installation
requirement for a built PostgreSQL source tree (for PostgreSQL
8.0 and up),
* JDBC2 support in Java classes, and
* A renewed and improved regression testing suite.
