TopoVista is a software package that allows one to interactively walk (or fly) over a surface defined by a U.S. Geological Survey Digital Elevation Model (DEM). It's based on Right-triangulated Irregular Networks (Algorithmica 30, 2) by Evans, Kirkpatrick, and Townsend.
We are no longer working on TopoVista, but you are welcome to download and use the software.
