[GRASS-user] Site Suitability like Arc Spatial Analyst

GRASS GRASS user
1

Grass list,

Anybody ever done a site suitability analysis exactly as ArcGIS Spatial Analyst would do? Ranking different variables per priority, inputing different layers, etc.? I'm quite sure this is possible using GRASS, I just can't really imagine how it would be done. Please point me in the right direction.

Thanks in advance,

If you have polygon data, convert each one to raster with weighted value.

Then use the map calculator to add together for a weighted map.

Hi Frank,

Is there is specific ArcGIS tool, or is this some kind of custom
analysis? The more detail you can give on the list, the better chance
of getting an answer!

Cheers,
