Convert GIS Lidar Geodatabase to DEM
I was given a Lidar raster in a file geodatabase that I want to use to delineate watersheds in PCSWMM. I've tried exporting it to TIFF but PCSWMM did not recognize it as a DEM format. I also tried exporting to GRID but the conversion did not keep any of the elevation data. I was able to convert a small section of the lidar to points, import the points, and build the DEM in PCSWMM but a larger area did not finish after 2 hours. Any tips?
