what=20 is more, then i write code with database spatial query for running in = any=20 machine, at this moment i can only do it in machines with postgis=20 installed.

Subject: = Spatial=20 extensions for Derby?

I'm wondering if=20 there is any interest in having/developing spatial extensions for=20 Derby?  I can see value in having Derby available as an=20 embedded database for working with large spatial=20 datasets.
 
I = expect that=20 adding spatial to Derby would involve:
- = defining=20 spatial types
- = implementing a=20 spatial index (probably an R-tree)
- = adding spatial=20 query and manipulation functions
 
As = the developer=20 of the JTS Topology Suite API, I would be happy to offer this = package as a=20 component of a spatial implementation in Derby.  Feel free = to=20 contact me if this is of interest.
