Hi all, I've been playing around with gdalbuildvrt lately and it has proven to be a very useful tool:)
What I'm attempting to do is take multiple RGB images and treat them as a single image using the VRT. This works great, but since the images are RGB, areas where there is no data are coming back as black. Is there a way that I can modify the VRT or the code to treat the VRT as an RGBA dataset and somehow say "If there is no data in any bands, the alpha is 0"? Thanks! Jason
