Publication_Date: 1999 Title: Geologic map of the Seldovia quadrangle, south-central Alaska Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Open-File Report Issue_Identification: OFR 99-18B Other_Citation_Details: 1 sheet, scale 1:250,000 Online_Linkage: http://pubs.usgs.gov/of/1999/of99-018/ Description: Abstract: USGS Open-File Report 99-18B is a digital representation of a paper map that is being released simultaneously, USGS Open-File Report 99-18A. The map shows the bedrock geology of the Seldovia quadrangle, Alaska, at a scale of 1:250,000, compiled from new mapping (1988-1993) and published sources. Digital files include various map coverages in Arc/Info export format, and a picture of the map plus all map-collar information in Adobe Illustrator and PDF formats. The map collar includes detailed map-unit descriptions, text on the physiography, neotectonics, geologic history, and economic geology, cross-section, correlation of map units chart, and map showing original sources of information. Purpose: Digital representation of geologic mapping of the Seldovia quadrangle, Alaska, is to facilitate the presentation and analysis of earth-science data. Digital maps can be displayed at any scale or projection, however the geological data in this coverage is not intended for use at a scale larger that 1:250,000. Supplemental_Information: The 1:63,360 scale geologic maps (ink or mylar topographic bases), from which the present map was compiled, are housed at the U.S. Geological Survey, 4200 University Drive, Anchorage, Alaska 99508. These show more detail than the present map, which was simplified, in places, for display at 1:250,000 scale.

Thomas Donley, and Patti Phillips Native_Data_Set_Environment: This dataset 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 1:63,360 scale mylar maps that were all in excellent condition. The arc and polygon attributes are based on field work and on previously published mapping that is cited, as appropriate, on an inset of the PDF and Illustrator files. Water bodies were digitized from the 1:63,360 scale topographic maps. Glaciers and permanent icefields were digitized from 1:63,360 scale topographic maps, but were modified as needed, based on 1978-1984 vintage air photos, where glacial retreat had been significant. The digital coastline, provided by the State of Alaska, Dept. of Natural Resources, was based on 1:63,360 topographic maps. This digital data set was prepared in the aftermath of the Exxon Valdez oil spill. The source of line- and polygon data is not coded in attribute tables. The map was checked for accuracy by visually comparing the digital product against hand-colored ozalids of the mylars. This thematic bedrock map depicts geologic units present beneath soil or relatively thin mantles of surficial deposits, not necessarily the surficial materials themselves. Logical_Consistency_Report: This coverage is a net coverage containing arcs and polygons. Each polygon has a class attribute classifying bedrock, surficial deposit, or water/ice body. Faults and stratigraphic contacts are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangling arcs may be present (faults, dikes, etc.) Completeness_Report: This set of digital coverages contains only the information used to create the geologic map. It does not include the files used to create the information shown in collar, or margins, of the paper version and graphic versions of the complete publication. 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. The Seldovia 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. Lineage: Process_Step: Process_Description: Linework was captured by hand digitizing from a stable base line drawing. The digital linework was edited and attributed using ARC/Info. The coverage was built for polygon topology, and had labels created and attributed. For the purpose of distribution, the coverage has been converted to an interchange format file using the ARC/Info export command.
