[OSGeo-Discuss] Open Geo Database

[Frank Hardisty]

David and All,

A nice up-and-coming open Java geodatabase format is H2 + spatial extensions.

The H2 database is by the same guy that wrote that HSQL db. H2 has
some good properties, most importantly, it's small (1 Mb), works well
in embedded mode, and is fast. Adding in spatial data in JTS format,
and providing a spatial index, is the basic concept.

Two implementations that I know of are

1. The French research group IRSTV, lead programmer seems to be Erwan Bocher.
http://geosysin.iict.ch/irstv-trac/wiki/H2spatial/Download

2. GeoTools has a H2 spatial module, written by Justin Deoliveira.
Here's a link to the compiled jars:
http://maven.geotools.fr/repository/org/geotools/gt2-h2/2.5-SNAPSHOT/

Both are under active development.

regards,
-Frank
