problem with Path Distance tool

Discussion created by simam on Feb 13, 2012
I have a problem with path distance tool:as longs as I define the source and cost raster as the inputs to calculate the rastre distance and backlink distance everyhting works fine and I get the results in two separate raster layers, however when I want to add more complexity to the tool e.g. adding the DTM as surface raster and Aspect (integer format) as horizontal factor, the outcomes contain nothing (it display raster distance & backlink raster on the table of content but they visulaize nothing on the screen and I don't know what could be the cause of this problem? Could you please help with this problem?

Looking forward to hear from you,
