Hello
How can i build a true color image from Landsat TM. When i combine band 3,2,1 as Red, Green and blue, I gain an false color combination. Means that vegetation will appear in red color. Could you please Help me to solve this problem. (I can not upload my files, there is not any option for uploading)

    It looks like Landsat TM would use bands 3,2,1 as Red, Green, and Blue.
    Band 1 is short (blue).

    Google "landsat color bands".

    Hi, following on with this query - I can't find in Global Mapper the option to merge/join these three RGB layers to make the true colour image - any help would be appreciated
