DescriptionGeoscience data are used for land-management decision-making, for engineering design, in the search for mineral resources, and for scientific research. Traditionally, geologic information has been stored and disseminated using geologic maps and written reports [Bernknopf et al., 1993]. Because of the complexity of the earth, much of the information included in a geologic map is buried in several layers of abstraction. Specific applied use of geologic data typically requires preparation of a derivative map designed to show a particular aspect of the geologic data. Such maps might be designed to show rock lithology without respect to age, the orientation of bedding or foliation in layered rocks, the acid buffering capacity of the rocks, or to show rocks of a particular age. Production of such derivative maps designed for a specific purpose commonly requires a geologically sophisticated analysis of the original map, as well as cartographic design and drafting of the derivative map. Computer-based geographic information systems allow the manipulation and analysis of much larger and more sophisticated geographic data sets than was possible using paper maps and physical overlays. These systems provide tools to manipulate and integrate geologic data with other geographic data to a greater extent than ever before possible. A well designed data-rich information system could automate much of the process of producing derivative maps designed for specific applications. This would free the data user to explore the data in more ways, and experiment with different representations of the data. Providers of geoscience data, like the Arizona Geological Survey, must redesign their information delivery systems to facilitate the integration of their geologic data resources into these automated systems in order to maximize its usefulness.
