TerraVision

TerraVisionTM is an Open Source distributed, interactive terrain visualization system developed by SRI International.

It allows users to navigate, in real time, through a 3-D graphical representation of a real landscape created from elevation data and aerial images of that landscape. There are many terrain visualization tools on the market, but here are some of the features that make TerraVisionTM unique:
-New: Full Open Source hosted on SourceForge.
-TerraVisionTM can browse huge datasets, in the order of terabytes.
-All data can be distributed over multiple servers across the Web.
-3-D VRML and GeoVRML models can be overlaid, e.g. buildings, wind vectors, etc.
-TerraVision can access OGC Web Map Servers (WMS)
-Datasets of different size, resolution, source, and coordinate system are supported.
