Hi,
Thanks Jukka, thanks Martin for your hints. I think I will try to solve
some of my problems using postgis-functions like Jukka supposed.
If I get round to I will try to deal with JEQL, too. Sounds promisingly.

It's based on the same geometry library as OJ (JTS), and is probably a
little more suited to running batch operations on large datafiles.
Feel free to contact me directly for more info.

Hi,
unfortunatily, I have to work with some very large vector-layers at the
moment (more than 800.000 polygons in some shape-files). I have to
select features by attribute, write some selections to new layers, union
features by attribute, etc. (classical GIS-tasks).
That's actually no fun!
