I'm looking for a FOSS GIS tool to provide Positive Topographic Openness on 32-bit Ubuntu. (which rules out ArcGIS)
Normally I use SAGA GIS for this, but my Ubuntu setup is a bit messed-up after a recent update, and SAGA is crashing on opening (I think it's down to a clash in GDAL versions, but that's a question for another day!)
Are there any other FOSS tools out there which provide this algorithm? I've looked in GRASS and Whitebox GAT but can't find this algorithm.
I understand Relief Visualization Toolbox offers this, but the Linux version only supports 64 bit, and I'm still on 32 bit..
