   Yes, it is. The location does not like the full path to be specified. So,

ERROR: Input raster map is outside current region

   When I look at the above output I see every parameter the same except for
the Input Unit Factor and Output Unit Factor. I don't know if that's for the height dimension or
the x-y coordinates.

   Regardless of that factor, the other values are the same so why the error
message?
