I am investigating methods to perform a simple least cost path analysis with gdal. By simple, I mean using the slope of a dem as the only cost factor. I would prefer to do using the python or .net ...
I am new to QGIS (just installed QGIS 2.0.1) and am having problems running any spatial analysis tools. I followed the instructions on how to call GRASS tools into QGIS, but when I try to run the ...
