Description
There is an error during cost path analysis when calculating the distance from the destination to the source. Either the analysis mask or the selected area is found to be along an absolute barrier, thus a path cannot be created.
Solution
- Make sure that the selection set of values or the extent of your analysis area contain values that are not along an absolute barrier.
- Check that the cost distance and cost back-link rasters have been created correctly and the cell values are not all zeroes or a constant value.
