I have four Landsat Images with different UTM (45 and 46 N) zones. Whenever I am going to mosaic them a white line is appearing (see the attache image). The attached image is observed after MNDWI calculation . Why this is happening? How to get rid of this error?
Decide the UTM zone to work with, between 45N and 46N. Reproject all images to be in the UTM zone you decided on.
Dear Amin,
In point no. 2 i wanted to say that, you make an AOI in such a way that only image portion come inside the AOI. Rest values (Zero) present outside the Image portion (where you are not able to see the land features by FCC generally zero) should be avoided.
See the satellite images is made up of two portion (a) image portion (b) background portion as shown in the image attached below. You are able to see only image portion and the background portion is not visible when you see using FCC. generally its values is one but some time it is something else. Try to remove it. Make an AOI as suggested in the figure and remove them. Rest all the steps would be same...
