I'm trying to add high resolution orthoimagery from the USGS to a mosaic dataset in arcMap. When I "Add rasters to mosaic dataset" most of the rasters load in fine, but some have strips of white area and other places are sort of grey, low contrast. I checked Update Overviews. Please see the image below as an example of the issue. Also, as you zoom in the grey/white areas go away. Any ideas?enter image description here

  • Is this over a military base or other critical infrastructure element? USGS data is downsampled or redacted as appropriate for homeland security purposes. – Vince Mar 17 '16 at 2:11
  • I've no idea concerning the grey ones but the white areas could be a result of the maximum downloadable images. Please have a look at the Mosaic Dataset Properties ==> Defaults ==> Download Properties ==> Maximum Number of Items Downloadable per Request – Propper Mar 17 '16 at 6:41
  • It is not over any critical infrastructure. The download settings didn't help. I went ahead and built footprints, seamlines, and rebuilt the overviews and all the white/gray areas moved to different locations. – R. Anderson Mar 17 '16 at 12:00
