Ugh ! I spent all day trying to figure it out what this means...tried everything to get my raster to re-display again.... feelling frustrated !!!
This thread has some ideas, but no definitive answers. Obviously, it looks like there is a problem with two of your rasters. Try creating the mosaic without them and add them in later.
Actually there is no way around to fix the problem. Even though I tried to delete the Overview folder and still not work...so what I did, yeah, had to re-do all over and got it fixed...
First thing I had to delete the corrupt one..
Create a new dataset
Add rasters with update overview only do not build boundary or footprints
Once you get all the raster done
start building footprints
then build seamlines
check for any overlaps issue
if there is one white anywhere, open up footprint and set up which one you want to set to 1 or 2 in the Z order
All worked out well..
The white hole you see here is a military area where they do not want to be display....in the 2009, there is a full of naip all over the state....
Retrieving data ...
