The VISualization of Terrestrial and Aquatic Systems (VISTAS) team, an NSF/BIO/ABI-funded collaboration among environmental-, computer-, and social-scientists, has integrated new technologies and computer science research into terrain visualization software for environmental scientists.  The system allows scientists to overlay 2D data onto 3D elevation maps to emphasize landscape topography and better understand how terrain affects ecological processes.  VISTAS also provides animations over time, fly-throughs, and analytics.
