Hello,
I'm doing viewshed analysis on telephone lines and I keep getting the following error messages:
ERROR 010004: All cells in Raster test_ned_1104.tif have the NODATA value. Stop execution.
ERROR 010160: Unable to open raster C:\Users\Administrator\Documents\ArcGIS\Default.gdb\Viewshe_tif1.
ERROR 010160: Unable to open raster C:\Users\Administrator\Documents\ArcGIS\Default.gdb\Viewshe_tif1.
Failed to execute (Viewshed).
The elevation raster data I'm using HAS values. When I pick a point, cell value and pixel values come up.
I have another shapefile, a line feature file and I've added OFFSETA and RADIUS2 columns to the attributes table so that the output raster will be limited to certain height and area. This is correct, right?
I don't get what I'm missing and it's driving me crazy. I can't seem to find relevant information on the forum either.
Could someone please help me with this issue?
Thank you!
