The Remote Sensing Information System DIVA

The Digital Interactive Venus Atlas (DIVA) is a remote sensing information system for a catalog of SAR radar image data from the Magellan mission to the planet Venus (1990--1994). The system consists of a Java based user interface accessible via the WWW, an image pyramid covering almost the entire Venusian surface, a remote interface to a data archive and a metadata catalog to retrieve quicklooks and information about available data sets. DIVA makes intensive use of Java's multi-threading capabilities to avoid the performance penalties of traditional WWW-based interfaces. Its state of the art user interface combined with a scaleable, clickable image map for interactively formulating spatial queries provides fast and easy access to the image catalog in a platform-independent way.
