Dear All,
I am using least cost path to model migration of wildlife through the
landscape. In my understanding from what I have read on this list and in the
grass manual I do the following steps:
1.) r.walk or r.cost for the cost distance.
2.) r.drain where the starting point is the end point
Hello,
i am not sure, but maybe this will help you a bit?
There is the vtkGRASSBrige:

Hamish:
so what you want to do is fit an ellipsoid to the polygon,
and then examine the radii of the major and minor axes.
