Hi there,
I'm trying to calculate slope based from a national DEM - USGS 3D Elevation Program (3DEP), found here: 3DEPElevation (ImageServer) - and am having trouble with the spatial analyst geoprocessing tool given the size of the raster. When I try calculating slope in ArcMap Desktop, I get an error message saying that the file is too large. When I use ArcGIS Pro, it processes up to 5% and then stops. I'm using a VM, so bandwidth is not the issue. Does anyone have any tips on processing national DEMs? Or are there any pre-processed national slope files out there that I could download?
Thanks!
