Hi List,
I'm using v.generalize in a script (excerpt included below) to smooth
the boundaries of a polygon vector dataset. In the attached example
(input_vector.png), I would like to *only* generalize the internal lines
(blue), and leave the external boundary (green line) unchanged. I

Micha,
Hi Stephan,
That is very interesting, and I see interesting potential uses for that.Does it
work for any type of input vector (points, polygons, lines)?
I am willing to test it and give you feedback.Some time ago I helped a friend
develop something alike, but (unfortunately) he was working on

Hi Rich,
My application for the module is characterizing sampling sites in ecological
research.
It is mainly a port of

Python - with some enhancements like multiple buffers, DB output, tabulating
classified raster data
