Hi everyone,
I ran into a behavior I couldn't find documented anywhere and wanted to check if anyone else has come across it.
I have a mosaic dataset with overviews generated and stored in a folder separate from the primary source rasters. Since the original orthophotos I'd loaded turned out to be incorrect and needed replacing, I used the Remove Rasters From Mosaic Dataset tool to physically remove all the primary rasters, leaving the overviews untouched in their own folder.
I expected the overviews to remain visible, at least at the scales they were built for, since they're independent physical raster files. Instead, as soon as the primary raster paths are removed, the overviews stop displaying as well. Interestingly, as soon as I add a new orthophoto back into the mosaic dataset, the overviews reappear.
Is this expected behavior related to how the mosaic dataset manages items (source + overview as a single row in the attribute table), or could it depend on something specific (overview format, ArcGIS version, mosaic dataset properties)?
Thanks in advance to anyone who's looked into this!
Mariano
