I was just wondering what are some of the methods that people use in ArcMap to remove these linear artifacts from a DEM so they don't show up in my Hillshade. The data are from USGS NED 10m.
I have ran several low pass filters, and this reduces the effect but does not get rid of the artifacts completely. Focal Statistics works well, but it really washes out/softens the Hillshade.
Any help on how to get rid of these or how to avoid the occurrence of them would be appreciated.
