I have downloaded two landsat TM images from USGS in different UTM (36 and 37) and may have different years. They were not specified as mosaic images by USGS but I checked both images have a common area. Today is the fourth day I spent to mosaic these images but I couldn’t. I tried arcgis and idrisi. . Idrisi told me the images have no the same spatialreference. ArcGis gave me distorted mosaic. the sattlite images have black background them which makes them even more difficult for me. i reformat raster to grid, raster to float etc. but nothing
Is there some one to help please?
