Does anybody no how to fill in gaps in a USGS DEM? I imagine the best way is to interpolate the missing values from the neighboring pixels. I believe there is probably a Raster Calculator formula. I have found a few in other forums but they never seem to work. This could be because they are done in older versions of ArcGIS, but I am not sure. I am working with 10.2. Any ideas? Thank you so much.
