I have contemplated acquiring imagery and processing it, but so far only contemplated. My impression is that you need to resample, not just compute a transform (hence gdalwarp vs vrt), because most things that use imagery expect at most only transform, scale and rotation. One thing that I found that may be useful is https://www.opendronemap.org/ however it seems to have "docker is the approach" which generally makes me suspicious of build system hygiene. That may just be spin and not real, though. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
