I have a mosaic dataset with rasters that cover the entire US - One for each county. When I generate the overviews, there is a chunk missing. When you zoom in, the imagery shows up. There are no errors or warnings from the analysis tool and there were no errors or warnings from the generate overviews tool. I expect that there may be a single raster that could be causing problems and preventing the overview image from generating. Does anybody have any troubleshooting ideas for me?
I'm using ArcGIS for Desktop Standard version 10.3. Below is a screenshot of the mosaic dataset as it is displayed in ArcMap. The green lines are the footprints of each individual raster. The rasters are .sid files.
