I am having some issues dropping a processed Landsat 8 image into the Color Balance Mosaic Dataset. The image has been processed through the following:

  1. Atmospheric correction QGIS
  2. Pan-sharpening ERDAS
  3. Topographic correction ERDAS model maker
  4. Cloud/shadow removal using unsupervised classification Arcmap

I have multiple images of the same area. I removed the cloud/shadow coverage and need to merge my images back into one to get only vegetation coverage. I read that I can use the color balance mosaic dataset tool to do histogram matching, but it will not open my file. The file format is .img. I tried saving it as a .lry, but I get the same error. I have also tried browsing to it through the folder button and can open the saved .img.lry file, but then get an error "The value is not a Mosaic Layer".

Any suggestions?

  • It's an IMG not a mosaic dataset desktop.arcgis.com/en/arcmap/10.3/manage-data/raster-and-images/… . It sounds like you've already done the mosaic in QGIS or ERDAS.. you will probably need to go back a step or two and repeat for each image then create a mosaic dataset in ArcGIS to color balance. – Michael Stimson Jul 10 at 4:25
  • Are you saying go back a couple steps in my above procedure? – Zman3 Jul 10 at 5:40
  • Yes, to the point where you have individual scenes of Landsat images with which you can create a mosaic dataset. The tool you're trying to use balances the colours of the scenes referenced by a mosaic dataset.. if you have only one scene the Color balance Mosaic Dataset tool will do absolutely nothing. – Michael Stimson Jul 10 at 5:54
  • Okay I understand, but my img file is not one color, it contains 6 bands. After my above procedures, would saving it as a tiff make a difference? – Zman3 Jul 10 at 5:56

    No, leave the post, if you were confused about what the tool does there's bound to be someone else who arrives at the same misconception. – Michael Stimson Jul 10 at 23:08
