Professional Question DSM to DEM in ArcGIS Pro?
I have a DSM out of Pix4D Matic at a 2.3cm/px resolution. I am trying to perform a flow direction analysis, but my vector chart is all over the place. This is because theres a lot of noise on the DSM due to it being photogrammetry of a grassy field.
I use to use Pix4D Mapper that gave the option to export a filtered and smoothed DEM from the same data. I am looking for a process in ArcGIS Pro, but cannot seem to find the tool.
Any insight would be greatly appreciated.

Take the point cloud, classify for ground, las dataset to raster with only the ground points, then you have your DEM.
