Geologic datasets for weights of evidence analysis in northeastWashington--4. Mineral industry activity in Washington, 1985-1997.
This report is a tabular presentation of mineral activities for miningand exploration in Washington during 1985 to 1997. The data may be incompleteas it depended on published data or data volunteered by operators.
Digital geologic map of the Spokane 1:100,000 quadrangle, Washington and Idaho: a digital database for the 1990 N.L. Joseph map
Geologic data from the geologic map of the Spokane 1:100,000-scale quadrangle compiled by Joseph (1990) were entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest. The map area is located in eastern Washington and extendds across the state border into western Idaho.
Digital geologic map of the Rosalia 1:100,000 quadrangle,Washington and Idaho: a digital database for the 1990S.Z. Waggoner map
The geology of the Rosalia 1:100,000 quadrangle, Washington and Idahowas compiled and published as a paper product by the WashingtonDivision of Geology and Earth Resources (Waggoner, 1990). The U.S.Geological Survey converted the geologic data to a digital geographicinformation system (GIS) format as part of a larger effort to createregional digital geology for the Pacific Northwest. The digitalgeologic map database can be queried in many ways to produce a varietyof derivative geologic maps.
Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. This dataset presents latitude, longitude, altitude, and magnetic-field values.
Cell maps for each oil and gas play were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in a play or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or dry. The well information was initially retrieved from the Petroleum Information (PI) Well History Control System (WHCS), which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying...
