I created a Mosaic Dataset from 6 different mosaic datasets showing aerial imagery from different dates. All of the imagery is from scanned aerial photos at the same resolution. When I go to scales between 1:3000 and 1:10,000, some of the images disappear, but their footprint is still visible. I have tried rebuilding my pyramids and overviews. Any ideas?
Also, I'm wondering if I can create overviews for the imagery for each date so that I can use time slider when viewing a smaller scale (that shows the overview). Is that possible?
