Background: running a least cost path analysis across mountains in middle east for archaeology project. Ideally, pick several points across an arbitrary interval distance (e.g. 1 km apart) and same for destination on other side of mountains.
Not sure which software to use. ArcGIS doesn't seem like it would do well with this kind of thing. I ruled out ArcGIS mainly due to favoring the r.walk module in GRASS and the ability to employ K-moves. The accumulated cost surface isn't all that relevant in this project because the scope is the Middle/Late Bronze Age and things like land use and vegetative cover (NDVI) just don't apply.
Considering the scope involves several origin/destination points in the foothills of a mountain range on either side, the cost surface involves slope and aspect purely (would've involved hydrology features but the data isn't there).
Moving forward, the project is broadly established as an LCA involving a set of paths that minimizes time, and another set that minimizes energy. The time/cost function seems ideally suited in GRASS r.walk; however I'm lost as to the specific workflow. The energy/cost seems like it could involve one of two processes. 1) manage a workflow with r.walk; or (since I'm much more familiar with ArcGIS) reclassify a slope raster with energy consumption data (i.e. Minetti 2002) and run the cost path tool while maintaining the aspect raster as backlink.
