GRASS tutorials, spec r.walk, r.cost

Question

Recently got enamored with the idea of doing a time-based and an energy-based least cost path analysis. After doing some research, I see that GRASS is the best for executing time-based given the k-move functionality. I'm only accustomed to ArcGIS, so I was wondering if there are any GRASS tutorials around that might be helpful, specifically to r.walk, etc.

Some more specifics on what I'm doing: using ASTER gDEM v2 (30m res) in Turkey study area for archaeological project. Doing several points of origin/destination across a mntn range.

Answer 1

For some basic tutorials and exercises for GRASS, you can check this link which I think is a great place for beginners. There are also a couple of other sources which describe the r.walk and r.cost functions and their associated parameters in greater detail (although I'm assuming you have already read these).

Answer 2

I ended up working through QGIS. Grass itself is quite overwhelming. Still having basic issues with projections, getting a hang of the data structure and executing r.walk.

Thanks all.
