Description:

Abstract:

This personal GeoDatabase feature class represents a compilation of reconnaisance geologic mapping of the Lookout Ridge quadrangle, Alaska.

Purpose:

This map is a product of the USGS Digital Geologic Maps of Northern Alaska project, which captures in digital format, quadrangles across the entire width of northern Alaska. Sources include geologic maps previously published in hardcopy format and recent updates and revisions based on field mapping by the Alaska Department of Natural Resources, Division of Geological and Geophysical Surveys and Division of Oil and Gas, and the U.S. Geological Survey. Individual quadrangles are digitized at either 1:125,000 or 1:250,000 depending on the resolution of source maps. The project objective is to produce a set of digital geologic maps with uniform stratigraphic nomenclature and structural annotation, and publish those maps electronically.

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracy of the data capture was evaluated by visual checks against the original publication by a person other than the person who captured the data.

Logical_Consistency_Report: Topologically clean; tested 2006

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Users of this digital geologic map should respect the intentions of the original mappers and the map compilers, and the limitations of the map. The Lookout Ridge geologic map is intended to be used at a scale of 1:250,000; it is not intended to be used at a more detailed scale.
