The free GeoViewer application replaces LizardTech's previous GeoExpress View utility that was offered for $299. GeoViewer 3.0 enables users to view and export layers from varied sources, such as local repositories, Express Server catalogs, and WMS and JPIP servers. GeoViewer supports a wide range of input formats and exports to GeoTIFF, PNG and JPEG. It's the most efficient means of viewing MrSID and JPEG 2000 images.
