Using ArcMap 10.8.1- I am trying to classify aerial imagery of a flooded are. While total size of the individual tiffs is 2.83 GB, the mosaic dataset is 107.66 GB. This is killing my hard drive space, maxing out my processing capacity and making classification extremely slow and ridden with problems. I have tried resampling and copying the mosaic as a new file, but the outputs fail. Do I have to reduce the size of each raster of the mosaic, or is there some way in adding the rasters I can reduce the resolution, or, somehow reduce the mosaic size after adding the individual rasters? I would appreciate any input. Thank you.
