Hello to everybody:
I want to use gdal_merge.py to mosaic four images. The images have the same
size, but the content of the images overlaps only in some areas. The value for
each images is something like : 1, 2, 3, 4
I want to mosaic all the files, but I want to be able to specify which image
will overlap what image, for example, the order of overlapping should be: 1
covers 2, 2 covers 3, 3 covers 4 without no blending (opaque), so the final
image will have values 1, 2, 3, 4, each values corresponding to its position in
the overlapping images
I have tried with: gdal_merge.py -0 merge.tif -of GTiff image1.tif image2.tif
image3.tif image4.tif, but I get the merge images with 0 values on most of the
image and a 4 value on the position of the last image
Please, may I receive and example for doing this?
Thank you
William
