VISualization of Terrestrial-Aquatic Systems (VISTAS)

VISTAS is designed to visualize modeledsoil data on a 3D topography, as well as a graph of measured rainfalland measured and modeled stream discharge data. The application alsoallows users to view data through time to see how the data changes.

The application also allows users to view multiple data attributes at the same time. The number of simultaneous views is customizable, as are attribute and graph line colors. Users can also export animation frames which can be combined using other software to easily create a movie of the data through time.
