Abstract:
Reconnaissance geologic maps and sample data, Teller A-1, A-2, A-3, B-1, B-2, B-3, C-1, and Bendeleben A-6, B-6, C-6, D-5, D-6 quadrangles, Seward Peninsula, Alaska, Open-File Report 69-236, provides 1:63,360 geologic mapping of parts of the Seward Penninsula, in western Alaska. This map was published by the USGS and has been scanned, digitized, and attributed by DGGS staff. The dataset contains geologic, structural, stratigraphic, and geochronologic data organized according to the GeMS and AK GeMS mapping schemas. The geodatabase and ESRI fonts and style files are available from the DGGS website: https://dggs.alaska.gov/pubs/id/10827.
Supplemental_Information:
This geodatabase is organized according to the Geologic Map Schema (GeMS) standard published as Techniques and Methods 11-B10 by the USGS. The conversion was performed within the framework and mechanisms of the Alaska Geologic Mapping System's AK GeMS mapping schema Hendricks, M.D., Ekberg, P.G., Athey, J.E., Wyatt, W.C., Willingham, A.L., and Naibert, T.J., 2021, AK GeMS data dictionary: A description of the Alaska geologic mapping schema: Alaska Division of Geological & Geophysical Surveys Miscellaneous Publication 170, 10 p. https://doi.org/10.14509/30669. The distribution package includes ESRI fonts and style files, along with usage instructions.

  2. How were the data generated, processed, and modified?
    Date: 2022 (process 1 of 1)
    GIS analysis and digital cartography - This data distribution package's geologic and geographic features were organized and attributed according to the AK GeMS geologic mapping schema. The legacy data were programmatically transformed to provide download options in three formats: (1) an AK GeMS data package that includes the complete AK GeMS database and associated files, (2) a GeMS data package that is a conversion of the AK GeMS database into the base GeMS standard published by the USGS, and (3) a shapefile data package that includes two simple shapefile representations of the data. Data sources used in this process:
    • Ekberg, P.G. and others, 2021
    • Hendricks, M.D. and others, 2021
    • U.S. Geological Survey National Cooperative Geologic Mapping Program, 2020
  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?
    Attribute fields within each feature class are populated using the map symbology and corresponding applicable values from the GeMS and AK GeMS specifications. When known, certainty in attribute interpretation is indicated in the relevant fields. Attribute accuracy varies throughout the map and is scale-dependent.
  2. How accurate are the geographic locations?
    This data release provides legacy geologic mapping converted to the GeMS and AK GeMS specifications. The data compilers used map symbology to determine positional accuracy. The data pairs descriptive fields within each feature class with location confidence lookup tables to record the originating authors' degree of confidence in the location of features. When location accuracy values are unavailable, users must infer positional accuracy based on standard geologic mapping practices of the investigation era. Certainty in feature boundaries or location varies throughout the map.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This work is complete. We encourage users to review the original USGS release for a print-formatted map and documentation of the original work.
  5. How consistent are the relationships among the observations, including topology?
    All polygon features were topologically validated according to the AK GeMS geologic mapping schema specifications.
