[GRASS-user] bayesian belief network analysis (was r.binfer)

[Saulteau Don]

OK thanks! I'll see if I can find an old grass executable, compile in a VM
with r.binfer in it or fallback to QGIS and OpenBugs. I thought I'd poke
around cause I prefer analysis in GRASS over any other platform out there :)

I've started to assist indigenous nations with assertion and
protection/preservation of their rights with GIS. Some of these analytical
methods like fuzzy/boolean patch modelling, weighted overlays, bayesian
belief networks (BBN) allow them to translate their oral history and
ecological knowledge into tools that help them engage effectively and
meaningfully with other parties such as other nations/governments and
industries who have expressed interest in their lands and resources.

I SO wish I could code or even knew what to ask for in procurement for
these things cause I would.

Been a lowly user, bug reporter, package maintainer and crowd funder.
Continuing to find ways to feed back and wholly contribute into these FOSS
communities any way I can.
