TerraVision(TM) 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.

It uses Tcl/Tk as UI-Toolkit.
