I am looking to calculate the total accumulated cost associated with traveling from a source point to a destination point (please see the included figure below, green dot = source, red dot = destination). I would like to use the ArcGIS "Path Distance" tool because I am interested in including horizontal factors associated with traversal as well as friction values associated with my cost surface (the cost surface is visible in the picture).

enter image description here

I'd like to know if it is possible to calculate total accumulated cost to my specific destination point, instead of just creating a path distance raster that calculates accumulated cost for the entire region. I have used the path distance raster and accompanying backlink raster as inputs for a least cost path, but I am getting an error output from Arc. The error message is general, and only states "failed to execute costpath".

How do I solve this issue?

I am using ArcGIS Desktop 10.6, and can use Python if it will be of assistance.

    The constant grey background suggests a constant value, would the path between these two points be a straight line? – Hornbydd Nov 23 '18 at 0:53
  • @Hornbydd Thanks for commenting. It is very possible that this example may produce a straight line, but I can't even seem to be able to produce a cost path! Something beforehand is creating an issue I believe but i'm not sure what. – Zach Nov 23 '18 at 0:56
