This upgraded version of GeoExpress, which allows geospatial professionals to compress and manipulate satellite and aerial imagery, offers exciting new features, including per-band compression ratios. This will allow users to choose different compression ratios for different bands in their images. For example, anyone with an eight band image can choose to compress the Red, Green, and Blue bands at 20:1, but compress all the other bands losslessly.
Additionally, users can now choose a subset of bands to encode. Previously, they could encode 1, 3, or all bands to MrSID. Now, they can choose any subset of bands. For instance, they can now choose six bands out of an 8-banded image to compress to MG4.
