Beikman and published by the US Geological Survey. The map is a regional summary of geologic formations and units that can be shown cartographically at 1:2,500,000. This digital dataset includes all (184) map units from the original map. 182 are geologic units; the others are polygons for large glaciers and lakes. This coverage is not intended to be a complete representation of the printed geologic map. It does NOT include the following features: faults, locations of volcanoes or volcanic vents, the map explanation, correlation charts or description of map units. Purpose: This coverage is intended to provide digital features (polygons) representing generalized geologic units in Alaska for use in small-scale spatial anlysis (statewide) with other coverages such as vegetation types, soils, geochemical values etc. Supplemental_Information: Procedures_Used The linework was digitized from a paper copy of the 1980 map at the EROS Data Center in Sioux Falls, South Dakota, and the resulting coverage (ARC/INFO version 5) transferred to the EROS Alaska Field Office. Although the latitude/ longitude grid shown on the published Beikman map was an Albers equal area projection, the geologic polygons were not in the same projection since they did not align with an Albers equal area coverage of the Alaskan coastline. A rubber-sheeting operation was performed on the geologic polygons using points along the coastline and major rivers to match an Albers equal area projection. In 1997, this coverage was imported into ARC/INFO version 7.0.4, and edited by the Alaska Section, Geologic Divsion, USGS. Map unit (polygon)locations and attributes were checked by three reviewers, by comparing a printed copy of the coverage to the original map. Metadata were collected using document.aml v. 7.1.1, distributed by ESRI, Inc. Revisions: None completed or planned.

Map SG0002-1T and 2T. Scale 1:2,500,000. Notes: The completeness and quality of the geology in the digital coverage is that of the original 1980 map. No recent data have been added. The geographic accuracy of the original published map has been slightly degraded by the rubber-sheet operation.

Intended use is at small scales (e.g. statewide, 1:2,500,000 etc.) only; enlargements of this data to scales greater than that at which they were originally compiled can lead to misinterpretation of data. The U.S. Geological Survey (Dept. of Interior) should be acknowledged as the data source in products derived from these data. Use of these data is not restricted; however, organizations, agencies, units of government or other users are responsible for its appropriate application.
