[OSGeo-Discuss] Any projects dealing with spatial joins?

[Jody Garnett]

We have just been looking at a proposal for a Join interface (an extension to our Query) interface in GeoTools. If you would like to drop by geotools-devel you will find this to be a topical subject.

The functionality of a join is part of the Web Feature Server 2.0 specification so you should find a lot of projects running into it as a concept over the next year.

The simplest case I'm thinking of is where someone picks 2 or more database tables (associated with location), and asks to see a combined table. No maps involved, just tables (with the overlapping ground area thrown in if we're dealing with a polygon/polygon overlay).

For example, I'm looking for a combination of A+B+C that covers at least 1000 hectares, but I'm starting with a database that covers the whole world. So to obtain some measure of efficiency, it would presumably be nice to have access to related
