An overview of PostGIS future developments: topology, networks, long
transactions and rasters.  Concepts, benefits and development state of
each topic will be discussed.

The PostGIS spatial extension for PostgreSQL is in wide use by the
Free and Open Source GIS community, providing a common service for most
architectures both in the C or Java worlds.  The advantage of using an
ORDBMS for storage of features data is a unified access method from a
wide range of programming environments.

While PostGIS in its current status provides the OGC-defined "Simple
Features" model and operations, lack of support for other models or
services forces applications developers to implement them in a custom,
thus not-reusable, fashion.

Future development plans are aimed at filling this gap by providing
standard ways to threat more complex models and commonly required
services.
