Many organizations addressing grand challenge problems, such as those defined by earth sciences, require the integration of both physical and human resource databases in an interactive manner. Such a capability allows reasonably informed policy analysts to query an ``environmental science workstation'' so as to better understand how human uses impact our natural resource base. This project involves a prototype software tool that supports access to and understanding of diverse environmental information. The tool, ENFORMS (Environmental Information System) is currently being developed for use in a regional watershed analysis project. ENFORMS consists of two general components: an object-oriented archive of multimedia information objects and a querying facility to search the archive for relevant information. The archive can be populated with a variety of different types of information, including documents, satellite imagery, aerial photographs, tabular data, color-coded charts, maps, and illustrative animations. The archive component also supports data integration activities using tools such as a geographical information system (GIS) and environmental models.
