I have a DEM (1x1m) whose hillshade shows like this:

enter image description here

As you can see, a grid shows up and that could be a problem for hydrological modeling.

Do you know why this happens?

How can I remove this grid from the background of the hillshade?

  • Get the original model - raster with floating point or use Float if this was imported from ascii file. If no source available, use focal statistics (mean)

  • Are you using ArcGIS Pro or ArcMap?
