[GRASS-user] least cost path between patches

Dear listers, I am trying to compute and represent the least cost paths between discrete patches (say distribution areas of a given species included in a landscape matrix). For training, I use a homogeneous cost surface (the landscape matrix, 'movecost') and a raster 'monkeygroup' of 12

[GRASS-user] least cost path between patches

Hi Patrick, If I understand the question, I haven't done this in GRASS, but one cumbersome approach without using a function like r.drain to find a cost distance *corridor* between two patches is to calculate a separate cost distance surface for every individual patch, from (and only from) that

[GRASS-user] GRASS workshop during a conf. in Wroclaw, Poland, May
