The following errors in ArcMap are preventing me from moving forward:
1) In Raster Calculator using "Aspect": "%DEM_Aspect%" <= 90 or "%DEM_Aspect%" >= 270
ERROR 000539: Error running expression: rcexec() Traceback (most recent call last): File "", line 1, in File "", line 5, in rcexec ValueError: The truth value of a raster is ambiguous. Invalid use of raster with Boolean operator or function. Check the use of parentheses where applicable.
I'm using SRTM1N34W087V2, 11-FEB-00 (Void Filled) raster.
I'm attempting to use ArcMap to accomplish the same results done in the QGIS tutorial Lesson 3: Terrain Analysis.
