Dear all Regarding the FOSS Geodatabase discussion, I would like to bring a different issue to the discussion.
It concerns whether we should be concerned with broadening the number of FOSS databases that offer support for spatial data, or whether we should focus on deepening and increasing the support for different types of spatio-temporal data on PostGIS. Consider a situation where PostGIS would demonstrably handle more spatial data types than Oracle and would do so efficiently. This would provide a tremendous leverage for all FOSS4G applications and developers. To me, PostGIS is to FOSS4G what Linux is for FOSS as a whole. It's the enabling platform for succesfull FOSS4G enterprise applications. By concentrating on PostGIS and associated tools, we will build a reliable and consistent set of tools.

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.

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.

You could try the freemap.in list - http://lists.freemap.in/mailman/listinfo/freemap - this is more a source of high-resolution data for particular cities than an india-wide effort. e.g. http://mumbai.freemap.in/ There's also an OSGeo-India local chapter, and i bet some overlap between these lists. http://mappinghacks.com/2005/08/22/open-geodata-policy-shift-in-india/ is an old blog entry with a bunch of India-policy links, but not data ;P I'm sure others will have more concrete suggestions. > and could point me in the right direction?

But I realize that's not how it's set up now, which was > why my answer was unconvincing. Recently when i run across unusual sets of particularly boundary and other vector data, I've been noting them down in the CKAN index - http:/www.ckan.net/ - at least this provides a way of publically noting name, url, keywords, that is guaranteed to stay around awhile. It has no spatial properties or query but is a place to start. http://www.ckan.net/tag/read/geodata I *have* been working on a CKAN-inspired spatial metadata/search project for a little while and would love to test out an open source release on OSGeo's systems but i don't want to talk about it too much yet Of course there's GeoNetwork, OSGeo's own "metadata catalog" system, I see they have a new release candidate due out very soon. It raises the bar somewhat, offering support for OGC and ISO standards which may be overkill for simple web mapping use cases. The more the merrier though, and there are plenty of systems resources to run all this stuff on, what's missing is peoples' time to setup and contribute to a repository effort that'll make future questions easier to answer without repeating ourselves :) cheers, jo ------------------------------ _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss End of Discuss Digest, Vol 13, Issue 25 ***************************************
