In 2024, USGS staff scanned, georeferenced, and projected the maps into GIS and corrected typographic and labeling errors with input from the author. DGGS staff subsequently converted these files into the GeMS geodatabase standard. The complete report, geodatabase, and ESRI fonts and style files are available from the DGGS website: https://dggs.alaska.gov/pubs/31429.This digital geologic data conversion product is intended to facilitate multi-map merging of adjacent work by USGS and State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (DGGS) staff.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.

When known, certainty in attribute interpretation is indicated in the relevant fields. Attribute accuracy varies throughout the map and is scale-dependent.All polygon features were topologically validated according to the AK GeMS geologic mapping schema specifications.This work is complete. We encourage users to review the original DGGS release for a print-formatted map and documentation provided in the accompanying report or map.This data release provides legacy USGS 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.Ekberg, P.G.Hendricks, M.D.Athey, J.E.2021AK GeMS symbology: A description of the AK GeMS style fileMiscellaneous PublicationMP 169Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys7 phttps://doi.org/10.14509/30584paper2021publication dateEkberg, P.G. and others, 2021GIS analysis and digital cartographyHendricks, M.D.Ekberg, P.G.Athey, J.E.Wyatt, W.C.Willingham, A.L.Naibert, T.J.2021AK GeMS data dictionary: A description of the Alaska geologic mapping schemaMiscellaneous PublicationMP 170Fairbanks, Alaska, United StatesAlaska Division of Geological & Geophysical Surveys10 phttps://doi.org/10.14509/30669paper2021publication dateHendricks, M.D. and others, 2021GIS analysis and digital cartographyU.S. Geological Survey National Cooperative Geologic Mapping Program2020GeMS (Geologic Map Schema) - A standard format for the digital publication of geologic mapsTechniques and MethodsTM 11-B10United StatesU.S. Geological Survey1 phttps://dggs.alaska.gov/pubs/id/30585paper2020publication dateU.S. Geological Survey National Cooperative Geologic Mapping Program, 2020GIS analysis and digital cartographyGeologic mapping - The Rawlinson 1993 surficial geologic map was developed through manual photointerpretation of color infrared aerial photographs using acetate overlays and a stereoscope, with map features transferred to a base using a zoom-transfer scope. Due to technological limitations in the 1980s, only low-resolution 1:250,000-scale black-and-white Landsat imagery was available for reference. Fieldwork conducted between 1981 and 1985 supported the photointerpretation, focusing on exposed areas along coasts, rivers, and gravel pits. This map incorporated data from 464 measured stratigraphic sections and 678 samples analyzed for grain size, radiocarbon and thermoluminescence dating, amino acid analysis, wood identification, and microfossil and pollen content. In 2024, the original paper maps were scanned, georeferenced, and digitized into GIS by USGS staff , with 100-200 typographic and labeling errors corrected in consultation with the original author. The digitized version retains the original 1993 interpretation of surficial geology and does not incorporate newer geological insights.2024GIS 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.Ekberg, P.G. and others, 2021Hendricks, M.D. and others, 2021U.S. Geological Survey National Cooperative Geologic Mapping Program, 20202025vectorAlaska Albers55.065.0-154.050.000coordinate pair0.00000000305360181585001630.0000000030536018158500163metersNAD83GRS 806378137298.257222101central_ak_arctic_coastal_plain_ak_gems_db_pkgGeodatabase, layer files, style files, and fontsDGGS and USGScentral_ak_arctic_coastal_plain_ak_gems_db_pkgcentral_ak_arctic_coastal_plain_gems_db_pkgGeodatabase, layer files, style files, and fontsDGGS and USGScentral_ak_arctic_coastal_plain_gems_db_pkgcentral_ak_arctic_coastal_plain_gems_geopackageSQLite Database fileDGGS and USGScentral_ak_arctic_coastal_plain_gems_geopackagecentral_ak_arctic_coastal_plain_gems_shapefile_pkgShapefiles and open data filesDGGS and USGScentral_ak_arctic_coastal_plain_gems_shapefile_pkgAlaska Division of Geological & Geophysical SurveysMetadata Managermailing and physical
