I mosaiced scanned slides/photographs by creating a mosaic data set within a file geodatabase. Besides the result looking pretty ugly, my most pressing problem is that the borders show up or go away depending on the scale. See Doc1.docx
At this point I am working on the mosaic of rectified images with the scale issue: showing borders at 1:40k and not 1:24K. I recreated the mosaic and this time around the inner borders won't to away at any scale. I've played with all the tools, such as calculate stats, build footprints, build boundary, build overviews. If it matters, the method I have used to rid the images of borders is by setting the minimum data value in Build Footprints at 75, if I recall correctly. Also, I get a black mask over the entire mosaic unless I select Percent Clip in Symblology.
Given your imagery doesn't have specific NoData values (you said you cut off the values from 0-75 using stretches) it sounds like to get this to work you need to create and edit polygon footprints to get rid of the collars. Then rebuild pyramids and overviews.
It sounds like you have already tried building the overlays, which does usually help if with strange behavior at different scales (ie sometime checkerboard patterns, etc). If you haven’t already looked at these links, they may offer some solutions
Edit: a few more link. I know that the check board isn’t your issue, but the solution may be similar...so not ruling out.
How to fix the checkerboard pattern in Mosaic Datasets This fix is if the path changed, ie broken links to source files
On another note, as Curtis suggested, it would help others find your question...and help others in the future... if you could edit your title with a short description,such as “issue with borders at different scales of mosaic dataset” or something similar. If you are not sure how to edit the title, one of the moderators would be able to help.
Thanks for the help, I have tried your suggestions, the links, to no avail. It looks like it will be easier and of higher quality to photograph a photograph of the entire area thus eliminating the need to mosaic.
By the way, my "anyone" subject worked--I received replies! I know it was bit obnoxious.
I have found mosaic datasets to be terribly finicky and my understanding is that they do work pretty well but require a lot of messing with to get them to work right. If you have access to tech support hopefully they can help you with your specific datasets. Sorry I couldn't be more help.
