Title:
Surficial geologic map of parts of the Misheguk Mountain and Baird Mountains quadrangles, Noatak National Preserve, Alaska
Abstract:
This dataset represents surficial geologic mapping of parts of the Misheguk Mountain and Baird Mountains quadrangles containing the Noatak National Preserve. It is used to create the mapsheet in 03-367, which shows surficial deposits of the 1:250,000 scale Misheguk Mountain and Baird Mountains quadrangles in north western Alaska.

    arcs
    Characteristics of the arc features in coverage noatakgeol are coded in noatakgeol.aat, the arc attribute table. The .aat consists of the following items: ARC-CODE and LTYPE. (Source: This dataset)
    ARC-CODE
    ARC-CODE is a positive integer value (3 3 I) item in the arc attribute table. Values range from 1 to 104. ARC-CODE identifies a stratigraphic boundary, fault, or other linear feature. The ARC-CODE is described by the item LTYPE. (Source: This dataset)

    polygons
    Characteristics of the polygon features are coded in the polygon attribute table. Table noatakgeol.pat includes the following items: CLASS, FORMATION (geologic unit label), NAME (geologic unit name), and COMPOUND. (Source: This dataset)
    CLASS
    CLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range from 1 to 263. Every unique unit has a unique CLASS value. Each CLASS value listed below is defined by the information from the FORMATION (12 12 c) item which contains the geologic unit label if one was assigned, and by the NAME (120 120 c) item which gives the name of the unit. Map units shown in parentheses indicate thin and generally discontinuous deposits above near-surface bedrock. Unit labels containing a slash indicate compound units where one unit is stratigraphically above another. Units queried where uncertain. (Source: Open-File Report 03-367)

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)
    • Hamilton, T.D.
  2. Who also contributed to the data set?
    This digital coverage was created by Keith Labay, SAIC contractor.
  3. To whom should users address questions about the data?

Why was the data set created?

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.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2002 (process 1 of 2)
    The linework was captured by scanning an inked greenline overlay to create a TIFF that was then heads up digitized. After digitizing 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. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The linework was captured by scanning an inked greenline overlay to create a TIFF that was then heads up digitized. After digitizing the file was attributed in ARC/INFO. The digital data has been visually checked against the original.
  2. How accurate are the geographic locations?
    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.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    These coverages were used to create the map portion of 03-367. Text files, tables, graphics, symbolsets, and topography shown on the map sheet are not included.
  5. How consistent are the relationships among the observations, including topology?
    Coverage noatakgeol is a network coverage containing arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Stratigraphic contacts and water boundaries are represented as arcs. There are two associated info files noatakgeol.lut and noatakgeol.lut2 that were used to assign symbols, overprints, and labels when plotting from ARC/INFO.
    Coverage noatak_pnt is a point coverage used to place symbols for directional arrows and passes.
