I am working with older imagery that has been manually scanned, and as expected, the fidelity of the images is more reliable towards the centers of the images. There is a good deal of overlap in the images that I need to mosaic, and it would be really helpful if I could mosaic them based on which raster's portion of the overlapping area is closer to its own center. Clearly this is not what the "closest to center" method does.
Another thing that could work is if I clipped out a portion of each image, leaving behind only a central area where the imagery is more reliable. However the images have already been georeferenced and this would involve creating a huge number of separate masks or rectangles. Since all of these images are about the same size, it would be ideal if there were a tool like "extract by rectangle," but where you could define the rectangle based on its position within the raster, rather than that of the overall data frame.
