Description:

Abstract:

This data set represents reconnaissance geologic mapping of the Christian quadrangle, Alaska. It is used to create the mapsheet in USGS OFR 00-192, which shows bedrock and surficial deposits of the 1:250,000 scale Christian quadrangle in northern Alaska.

Purpose:

Digital representation of geologic mapping facilitates the presentation and analysis of earth-science data. Digital maps may be displayed at any scale or projection, however the geologic data in this coverage is not intended for use at a scale larger than 1:250,000.

Data_Set_Credit:

This digital coverage was created by Keith Labay and David Pray, Raytheon STX contractors.

Native_Data_Set_Environment:

Data set was created using ESRI ARC/Info version 7 on a Unix platform.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The linework was captured by hand digitizing from a hand-drawn 1:250,000 scale paper map. Vector and polygon attributes were obtained from a compilation of field maps and other compilations. The digital data has been visually checked by and the geologic map has undergone technical review.

Logical_Consistency_Report:

This geology data set is a network coverage containing arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, moraines, etc.)
Coverage csfold is an arc coverage containing fold axes information. Coverage csstruct is a point coverage, with annotation, containing strike and dip information. Coverage csfossil contains the fossil locations.

Completeness_Report:

These coverages were used to create the map portion of the Christian geologic map. Text files, tables, graphics, and topography shown on the map sheet or pamphlet are not included.

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 limitations of the map. This geologic map compilation is intended to be used at a scale of 1:250,000; it is not intended to be used at a more detailed scale.

Lineage:

Process_Step:

Process_Description:

This data was hand digitized in ARC/Info from a hand-drawn 1:250,000 scale paper map. The arcs and polygons were attributed. For the purpose of distribution, the coverage has been converted to an interchange format file using the ARC/Info export command.
