Here is an excerpt from the Geospatial Solutions Government & Military blog. Head on over there to get the full story : "Recently, Google Earth changed the picture by creating a very easy-to-use spatial viewing environment. This really opened the eyes of the world and introduced non-GIS people to the world of spatial data. The Google environment was simple to understand, but somewhat limited to viewing spatial data and imagery with no real spatial analysis capability. It was especially good at organizing spatial data for visualization. ESRI soon followed, offering a more robust viewer that could be best described as a professional version of Google Earth with spatial analysis capability. However, one still had to suffer through the zoom-in globe. As good as life became with both Google Earth and ArcExplorer, there was still room for improvement. Then, several months ago, I saw a demonstration of ERDAS TITAN (formerly known as Leica TITAN). TITAN takes spatial data sharing, viewing, and publishing to a new level. It seems to magically ingest almost any spatial data format, read it, use it, and publish it back out in any format — and do so quickly. It does for spatial data what the Babel fish did for language and speech. A universal translator designed for sharing and the sharing environment is completely controllable via permissions, so you don't lose data ownership. TITAN delivers data via geospatial Web services, such as Web Map Services (WMS), permitting you to view spatial data without actually getting access to the source dataset. "
