Base imagery displayed wrong though service overview is correct

NeoGeo — Thu, 13 Jun 2013 07:47:57 GMT

I have 4 band NTF format imagery that I made a mosaic dataset out of. When I open the mosaic dataset in ArcMap 10, the service overviews display fine other than needing some stretch and different band combo, but once I zoom down to the base imagery it displays incorrectly, almost as if it is using a different band combination for the base imagery.

I applied an extract bands function using layers 3 2 1 and added a stretch function so now the service overview comes into ArcMap displayed perfectly, but zooming into the base imagery it is still messed up. I have also calculated statistics. Once zoomed in to the base imagery, no combination of bands looks correct and it does not matter whether I use extract bands or not.

any ideas?

Thank you!

The problem was a misunderstanding of the data on my part. Each RGB image has a single band counterpart. I simply built the whole workspace into my mosaic dataset as usual and as a result the single band images were displaying once I zoomed down to the base data. What I needed to do was just build the mosaic dataset using the RGB images. I did not notice initially when I brought the separate images into ArcMap because the stretch was so far off that all of the images looked panchromatic.

I am still curious as to whether the single band images could be used to pan sharpen the RGB data, but I know nothing about this dataset and as usual there is no metadata.
