cost path distances with pre-defined sources and destinations?

Discussion created by chrislloyd2 on Aug 4, 2010
Hi all,

I have some polygon - polygon, and polygon - point (source - destination) features. These match as pairs (by an attribute in each of their respective feature attribute tables). I would like to calculate a cost path (by slope map of dem) between these pairs (specifically), and then be able to calculate the distance of the path. Is there a way to do this? I have experimented with the spatial analyst distance tool set but can find no obvious way of predefining the source - destination pairs. Hope someone can help?
