I have an image mosaic of 5 Landsat TM5 scenes. Where the scenes overlap there is a dark band, only on the left and right sides, but the top and bottom are seamless. What is the best way to correct this in Erdas 2011?
If you are doing the mosaicing, I would suggest using the Mosaic Pro tool and then setting the "Set Overlap Function" (fx icon) to Maximum. If the overlapping bits are 0 or Null data it will take the highest value, in this case the imagery and exclude the edges.
