Hi, Is there a way to store nodata values in GeoTiffs that don't match an RGB value? I used either white or black as nodata values, but in some rare cases these black or white pixel values do appear as valid data in the image.
How can I properly store nodata values in RGB Orthoimages in GeoTiffs where the borders aren't purely rectangular? Would I have to use a hard mask for regions where there is no data, or is there a trick with an alpha band? Thank you for any hints and greetings, Andreas
