I have a bunch of SAR images (about 1 GB each) on which i need to do some image processing. Each image is georeferenced and there is significant overlap between each pair of images in the set ie. one piece of terrain appears in 2 or 3 of the images. To reduce the amount of work in the image processing step, is there some way to extract out the approximate areas of overlap between the images ? Specifically, does the GDAL C++ API provide any such functionality ?
I have tried reading the documentation of the API but i couldn't find anything.
