Still very confused. I have a tiff file. I want to get the metadata for that tiff but in EPSG:4326, without actually warping the image. I can use CoordinateTransformation to do this, but again it gives me different results than gdalwarp.
I will use gdalwarp later (realtime) to serve out an image. But if the metadata I store (from CoordinateTransformation) is different than the metadata when I warp I will run into problems. gdalwarp gives something like minLon = 30.300001234, but CoordinateTransformation gives minLon = 30.29988787. I want to gdalwarp number but without actually warping the entire image. I am not sure what .vrt file you are talking about.
