The Virtual Reality Mars Atlas User Interface (VR-MAUI) provides an atlaslike interface for access to Mars data. This access is provided via the World Wide Web, using JAVA. Within VR-MAUI, images are organized as maps. These maps provide a natural coordinate system, which defines feature locations. VR-MAUI is used to (1) examine, process, display, and analyze variable-resolution images of Mars and (2) interactively create VRML models of the Martian surface. VR-MAUI provides a point-and-click interface for selecting a specific location on Mars. Users identify locations by image features, pixel coordinates, or map coordinates. Data can be displayed in the forms of text, maps, still images, movies, and VRML models.

The current version of VR-MAUI provides an interface to Viking and Mars Pathfinder data. Future versions will provide similar access to other objects in the solar system. When fully developed, VR-MAUI will (1) display planetary surfaces and atmospheres in three dimensions using VRM and (2) display and analyze spacecraft and instrument data during flight operations.
