Description
LizardTech’s GeoExpress software compresses massive geospatial images and LiDAR data into high-quality MrSID files that can be opened and viewed immediately. Your 100MB image file becomes a 5MB file with the same high resolution quality. And, the MrSID file type is supported in all geospatial platforms, so there’s no need to spend money on additional formatting software or constant updates.
