    Description: 
      Abstract: 
      This digital map database represents the general distribution of major 
      structures, lithologic contacts, faults, folds and gravity anomalies in 
      the state of Alaska and dominant movement along these faults. This 
      coverage is a digital version of linework from the previously published 
      map, Map showing sedimentary basins of onshore and continental shelf 
      areas, Alaska, C. E. Kirschner (1988). The scale of the source map limits 
      the spatial resolution (scale) of the database to 1:2,500,000 or smaller. 
      Purpose: 
      This database depicts the distribution of major structures, faults, folds 
      and gravity anomalies in the state of Alaska as shown on C. E. 
      Kirschner's, Map showing sedimentary basins of onshore and continental 
      shelf areas, Alaska (1988). This coverage includes linear features only, 
      with polygon features included in an accompanying coverage. The regional 
      (1:2,500,000) scale of this coverage does not provide sufficient detail 
      for site development purposes and this map does not take the place of 
      fault-rupture hazard zone maps. Similarly, the database cannot be 
      substituted for comprehensive maps that systematically identify and 
      classify active fault movement. This coverage is intended for use as a 
      base map for the accompanying open-file report "Map and digital database 
      of sedimentary basins and indications of petroleum in the Central Alaska 
      Province." 
      Supplemental_Information: 
      This database was digitized from previously published data and was 
      compiled in ArcInfo, a commercial Geographic Information System 
      (Environmental Systems Research Institute, Redlands, California), version 
      8.2.0. The files are coverage (ArcInfo vector data) format. Coverages are 
      stored in uncompressed ARC export format (ArcInfo version 8.2.0). ArcInfo 
      export files (files with .e00 extensions) can be converted into ArcInfo 
      coverages in ArcInfo and can be read by some other Geographic Information 
      Systems, such as MapInfo and ESRI's ArcView (limited versions of this 
      software are available for free from ESRI's web site: 
      <http://www.esri.com>).

    Access_Constraints: none 
    Use_Constraints: 
    Uses of this digital coverage should not violate the spatial resolution of 
    the data. Although the digital form of the data removes the constraint 
    imposed by the scale of a paper map, the detail and accuracy inherent in map 
    scale are also present in the digital data. The fact that this database was 
    edited for a scale of 1:2,500,000 means that higher resolution information 
    is not present in the dataset. Plotting at scales larger than 1:2,500,000 
    will not yield greater real detail, although it may reveal fine-scale 
    irregularities below the intended resolution of the database

      Process_Step: 
        Process_Description: 
        This database was digitized from previously published data. The geologic 
        map information was digitized from stable originals of the sedimentary 
        basins map at a scale of 1:2,500,000. The author's paper map was scanned 
        on a large-scale, flatbed, color scanner with a resolution of 600 dots 
        per inch. The scanned image was georeferenced interactively to a USGS 
        coverage of the state of Alaska using ArcInfo georeferencing software 
        and rectified with a first order polynomial transformation. The line 
        features were digitized interactively by hand using ArcInfo.

    Resource_Description: 
    Downloadable COVERAGE (ARCInfo vector data) format. Coverages are stored in 
    uncompressed ARC export format (ARCInfo version 8.1.2). ArcInfo export files 
    (files with the .e00 file extension) can be converted into ARCInfo coverages 
    in ARCInfo and can be read by some other Geographic Information Systems, 
    such as MapInfo via ARCLink and ESRI's ArcView (limited versions of this 
    software are available for free from ESRI's web site: 
    <http://www.esri.com>). 
    Distribution_Liability: 
    The U.S. Geological Survey (USGS) provides these geographic data "as is." 
    The USGS makes no guarantee or warranty concerning the accuracy of

    on computers at the USGS, no warranty, expressed or implied, is made by the 
    USGS regarding the use of these data on any other system, nor does the fact

    incidental, indirect, special, or tort damages of any kind, including, but 
    not limited to, any loss of profits arising out of use of or reliance on the 
    geographic data or arising out of the delivery, installation, operation, or 
    support by USGS. This digital database of historic indication of petroleum 
    in the central Alaska province is 1:2,500,000 map-scale and any derivative 
    maps thereof, is not meant to be used or displayed at any scale larger than
