Hi,
I am attempting to run the Sink Evaluation tool (after using the Sink Prescreening tool), but I get the error "Spatial Reference does not have z unit. Z factor computation did not succeed. Do you want to use a factor of 1?"
As suggested, I attempt to modify the prj.adf file, and I save it, and then re run Sink Evaluation, but I get the same error. The prj.adf files I am modifying are in the local directory in Layers/PreFillDeM and Layers/Sink. When I open the prj.adf files in Notepad they seem to continuous lines of text (i.e.no new lines after each parameter). I change the text following ZUnits from NO to0.017... (my DEM Z units are in degrees), being sure to keep the same spacing, etc. I am not sure why I still get this error. Any help you can give wqould be greatly appreciated!
