Raster catalog color issues

[ChrisMathers]

We just moved to SDE and I made raster catalogs (unmanaged) for five years of aerials. The aerials look fine when I bring them into a map individually but when I bring in the catalog, the colors look like an oil slick. Anyone know why the catalogs have made my rasters all double rainbow?

Greetings,

do you mean when you see the pixels they changed colors, or did the footprint polygons change colors? If the problem is the footprints then it might be because your source images are no longer accessible.
Can you post a screenshot of your issue?

Attached is a page with two data frames. The top frame is the raster catalog. The bottom frame is the individually added .sid files.

Hi,

I think part of the reason why the datasets look like they do is because you load them into SDE. In SDE you can only have a managed raster catalog. Unmanaged raster catalogs are not supported. As such you load your data into SDE, and part of the loading creates statistics. This is why certain tiles display differently. You can try to load an unmanaged raster catalog in a file geodatabase or personal geodatabase to see if you get the same results.
If you have version 10 you could also try a mosaic dataset (like an unmanaged raster catalog in SDE).
Let me know if this helps.

Actually this is in a file gdb. My boss had me make the raster catalogs and we were going to load them into the SDE at night along with some other data. Previously we have been using raster catalogs that appear to just be a dbf with the file paths as attributes. These are not stored in a geodatabase of any kind.

Does it help if you change the renderer stretch type to none?

[ChrisMathers]

Stretch type was none already. The RGB band however were all set to <default> so I set them appropriatly to 1,2,3 and like magic the rainbow effect is gone. Thanks for you help.

Thanks for the helpful post.  I had the same issue, the bands were all set to default and the stretch type was on standard deviation.  It is good now!
