Scenome is software designed for building geo-referenced terrain databases from industry standard GIS formats such as DEM and GEOTIFF. There are two versions of the platform, the light commercial version and the heavy commercial version. Each version has the same fundamental elements but there are differences in features and licensing terms. The entire light commercial platform as a free download. You can develop extensions and applications with the light commercial platform; however the light commercial platform, while free, does not have some key features.
