I'm trying to mosaic images in envi 4.3 but sometimes there are some gaps between matching images. Sometimes I can remove this gap by changing image position to top or bottom but sometimes it doesn't work. Can anybody help me?
My first thoughts are: (1) are the images in the same geographic/projected coordinate system? If not, they should be reproject to a common coordinate system first (2) do the images have some frame around the image content? If yes, at least one of them should be striped.
