    How do I mosaic 4 images together so they appear as one big image without any black lines in between them? Basically, i want them to appear next to each other... Pixel based? Using ENVI 4.8 Thanks!

    Do the images overlap and are they geo-referenced? If so there shouldn't be any seams if they aren't georeferenced then pixel base is the way to approach this.

    They have a projection assigned to them... So, yes they are geo-referenced.... I tried the georeferenced mosaicking in Mosaicking tool but the black seam (value -9999) is there still... there is a cross in the middle of the 4 images...

    Do the images overlap along the edges? In order for there to be no black seam portions of one image should be visible on its adjoining image. If there is no overlap you may not be able to remove the black seam. How many pixels wide is the seam?

    I figured it out.... i needed to do a "Import Files and Edit Properties" and then ignore NoData value -9999... everything is lined up perfectly now Thanks
