I have a mosaic dataset with GeoTiff Rasters. Some of the rasters disappear when I zoom-in past 1:20,000. This does not happen with the individual rasters, only when in a mosaic. Any ideas as to why this might happen? I have changed the image request size to incredibly large. I have rebuilt it from scratch several times. Each time this keeps happening.
Thanks.
