Dear all Does anyone have a tutorial or an example of how to create heatmaps or hotspots based on point density in GRASS. I tried to use v.kernel but not sure what some of the parameters mean? v.neighbor is straight forward but the output map is very coarse. Cheers Sab _

[GRASS-user] r.terraflow for cost path analysis

A recent article published in the Journal of Archaeological Science (http://dx.doi.org/10.1016/j.jas.2010.11.006) proposed a method where hydrology models could be used on the product of a cost surface analysis to create a network of paths (instead of just the one made with r.drain -d). The flow ac
