just as another note, as of GRASS 7 it looks like they will be moving their default DB format to SQLITE instead of the traditional DBF format http://grass.gdf-hannover.de/wiki/GRASS_7_ideas_collection#Database it might make sense to have a community effort contribute to this as a whole. The positive side is that there is already adoption of an OSGEO product as GRASS is moving in this direction. Determine a comon schema that can be shared around between projects and voila. Or we could ignore this and then revist this same issue again in the future with no movement forward. just thought I'd share. Cheers

Just didn't seem like a quick enough payoff to try anything out. At least not on the surface. There was a thought that there might be something to start with though. bobb Miguel Montesinos wrote: Hi, ¿Does anyone know about similar projects using object oriented databases, such as db4objects[1], which is a GPL product with native engines for Java, Java ME, Mono, .NET, ...?

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 On Jan 14, 2008 3:14 PM, Sampson, David <[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> wrote: Hey Folks, Just wondering if there is still thought out there from the previous thread about a portable and open geodatabase. I came across the nemesis project "an experimental finite element code. Utilizes SQLite to store, handle and retrieve geometry and analysis data. " http://www.nemesis-project.org/index.php/Main_Page Thought that might be a good place to start that is already using geometry in sqlite. As for software adoptions it looks like GRASS already has an SQLITE driver. QGIS looks hopeful. Here is a GRASS/QGIS-SQLITE tutorial http://whatnick.blogspot.com/2007/12/using-sqlite-with-qgis-grass-tool box.html GDAL has some SQLITE http://www.gdal.org/ogr/drv_sqlite.html Just some more info for the fire.
