[GRASS-dev] GEM Wizard question

[Benjamin Ducke]

As far as I am aware, there are only a few extensions that I have
created that actually make use of GEM, so far (sniff).
Most importantly, spatial predictive modelling (which includes a generic
Dempster-Shafer Theory framework for evidence-based modelling with
raster data) and some advanced viewshed modelling with cumulative
viewshed analysis. The newest version of GEM is already included in the
GRASS 6.3 CVS and the executable is called "gem6".

Everything can be downloaded here:
http://www.uni-kiel.de/ufg/ufg_BerDucke.htm (bottom of page).

However, I am currently hard at work migrating the code to Win32, doing
a lot of bugfixing, etc. which is all made more complicated by a number
of issues that currently exist in the Win32 version of GRASS (argh!).
So I cannot currently support these versions of my extensions, due to a
lack of time. As soon as the Win32 stuff has been smoothed out, I will
substantially update my code base, documentation etc.!

There is also a pretty flexible territorial modelling tools in the pipeline.

Best,

Benjamin
