" GRBib", the bibliography of existing geologic maps and literature for 235 NPS units is available on the Internet ( URL: LOGIN: "geobib read", PASSWORD: "anybody") and is also prepared as printable documents at NPS.gov/grd/geology/gri/products/ The group discussed and adopted the four main inventory phases that are reviewed briefly below. At the meeting, Colorado, Utah, and North Carolina were chosen as pilot project states to maximize cooperation among the agencies and provide consistency in workshop planning. Its purpose was to receive input from the NPS, USGS, state geological survey personnel, and cooperators on needed basic geologic data that the NPS Inventory and Monitoring Program could provide. In the fall of 1997, the NPS Geologic Resources Division and Inventory and Monitoring Program sponsored a workshop on baseline geologic data in Denver, Colorado.
" GRBib", compilation of a bibliography of geologic literature and maps.The GRI for the 272 park units with significant natural resources consists of four main products: Geological Survey ( USGS), and individual state geological surveys. Cooperators include the NPS Geologic Resources Division, NPS Inventory and Monitoring (I&M ) Program (Natural Resource Information Division), U.S. The NPS Geologic Resources Inventory ( GRI) is a cooperative endeavor to implement a systematic, comprehensive inventory of the geologic resources in NPS units. Geologic maps describe the underlying physical conditions of many natural systems and are an integral component of the physical science inventories stipulated by the National Park Service ( NPS) in its Natural Resources Inventory and Monitoring Guideline ( NPS-75) and the 1997 NPS Strategic Plan. īedrock and surficial geologic maps and supporting information provide the foundation for studies of groundwater, geomorphology, soils, and environmental hazards. The evolving geology- GIS model is based on the Washington State ArcInfo GIS data model (Harris 1998) that is being adapted for ArcView GIS and extended to include components of the North American Geologic Map Data Model (NADM). Applications including the NPS-developed ArcView Theme Manager, graphical cross section viewer and legend text display tools are integrated with a standard geology- GIS model that is in development to reproduce the components of a "paper" geologic map into a digital geologic database. main users are NPS Natural Resource Managers) GIS tools have been developed in ESRI ArcView format for the digital geologic maps.
GRI workshops have been held for 56 parks, geologic bibliographies developed for 235 parks, digital geologic maps produced for 11 parks (numerous more in progress and nearing completion), and geologic reports produced for 11 parks in Utah.
