Hello list, I'm wondering if anyone has any recommendations for reprojecting a large, already-tiled RGB GeoTiff image dataset. It's straightforward enough to script the reprojection of individual tiles, but this leaves black wedges on the sides. I can merge tiles and add '-n 0' to treat the black wedges as no data, and the merged output looks fine with no visible black strips, but this is a dataset that is of the order of 60GB, so merging all of the tiles takes a particularly long time.
I thought maybe I could use gdal_retile.py...except that doesn't include an arugment that allow for the exclusion of a particular nodata value in the output. I figure I could incorporate something to account for nodata into a customized version of gdal_retile.py script...would anyone have any pointers for doing this?
