[GRASS-user] r.cost source ID question...

[Jonathan Greenberg]

If I have a r.cost surface calculated from a set of vector points used 
as starting points, and some cost surface, is there any way to easily 
retrieve the SOURCE vector ID that leads to the lowest cost to get to 
any cell in the raster?  E.g. from a given point, where is the point 
that costs the least to get to?
