When saving a georeferenced orthomosaic as a new file I am experiencing drastic increases in size compared to the original (9GB -> 40GB)
cell size different? bit type changed?
Anything that is different between the original and georeferenced besides coordinate space definition?
Original TIF might have some type of compression, typically LZW. 'Maintain Clipping Extent' might have also forced a smaller cell or larger raster dimension size.
