How does reprojection work?
You can now reproject your existing MrSID imagery without having to revert to the original TIFF files or export to TIFF. Simply add your existing MrSID images into the intuitive user interface and select an output coordinate system. If your existing imagery already has an EPSG coordinate system, GeoExpress will automatically read it. You can also combine raw imagery such as TIFF with existing MrSID imagery, even if they are in different coordinate systems.
