I have produced a mosaic of raster files in ArcMap using Create Mosaic Dataset and Add Rasters to Mosaic Dataset. At this point I have a dataset which appears to be functioning fine, however when I attempt to use the Hillshading (Spatial analysis) tool it develops holes. These holes are not always in the same places.
The Hillshading tool gives me no errors. The image below shows the same geographical area, with the raster mosaic and the hillshading.
Any help with solving this would be much appreciated.
