Hi Wolfgang,
this is a great news! Many thanks to the Department of Health and
Environment of the City of Munich! This is the power of the open source
software!!! :)

Very useful. It increase the portability of gvSIG project (.gvp).

I have already tried and it works like a charm! ;)

This one sounds very useful too!

This tool remembers of linear referencing (or dynamic segmentation).
It can be very useful too.

This one was just covered in part by SEXTANTE "Tools for vector layer"
--> "Autoincrement value" tool, however it's another good improvement.
It can also be used to concatenate the rec numbers as strings into other
fields, great!

Very interesting! I have to try it yet...

Just a few questions to gvSIG developers:
Will these new tools be integrated in the next version of gvSIG (like
NavTable) or remain as separate extension?
Will these tools be ported into SEXTANTE library as gvSIG algs for an
useful and better integration of them? I think that this is a good
point: is it better to have standalone tools or tools which can be used
together (i.e. in a SEXTANTE model)?
