Title:

Preliminary geologic map of the northeast Dillingham quadrangle (D-1, D-2, C-1, C-2)

Edition: v 1.0

Description:

Abstract:: This map with associated digital databases result from bedrock field mapping conducted in September 2000 and August 2001. Surficial deposits are mapped mostly from air photo interpretation with limited ground observations. This map is part of a larger compilation effort covering the Dillingham, Taylor Mountains, Lake Clark, and Iliamna quadrangles.
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 1:100,000.
Supplemental_Information:: This report consists of sets of geologic map and radiometric age database files (ARC/Info coverages) and supporting text files. In addition, plot files (Post Script and PDF format) showing a presentation of the data are included.

Data_Set_Credit:

The geology coverage, dinegeol, was created by F.H. Wilson. The radiometric age sample location coverage, datesdat, was created by F.H. Wilson.

Native_Data_Set_Environment:

These data sets were created using ESRI ARC/Info version 7 on a Unix platform.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Linework was captured by hand digitizing hand-drawn geology from paper 1:63,360 scale topographic map base. Vector and polygon attributes were obtained from compilation field maps and other sources. Surficial deposits and linear features were mapped from air photos on the topographic base. The digital data has been checked and the geologic map has undergone technical review.
The locations of the radiometric age samples were obtained by digitizing field station location on field maps or using GPS locations obtained during field work.

Logical_Consistency_Report:

The geology coverage, dinegeol, 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, linears, etc.)

Coverage datesdat is a point coverage showing the locations of radiometric age samples. Points have attributes which briefly describe the sample, dating method, and age.

Completeness_Report:

These coverages were used to create the map portion of the northeast Dillingham quadrangle. Text files, tables, graphics, and topography shown on the map sheet or pamphlet are not included in this data set.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Users of this digital data set should respect the intentions of the original mappers and the limitations of a thematic map. This geologic map compilation is intended to be used at a scale of 1:100,000; it is not intended to be used at a significantly more detailed scale.

Lineage:

Process_Step:

Process_Description:: The linework for geology coverage dinegeol was hand digitized from hand-drawn geology on paper 1:63,360 scale topographic map bases. The arcs and polygons were attributed. For the purpose of distibution, the coverage has been converted to an interchange format file, .e00, using the ARC/Info 'export' command.
