Description:

Abstract:: This is a digital version of Charles E. Kirschner's map titled Map showing sedimentary basins of onshore and continental shelf areas, Alaska, USGS Miscellaneous Investigations Series (I-1873), 1988. This coverage depicts geologic polygon features of Kirschner's map, including sedimentary basins, bedrock geology, basement rocks, gravity anomalies, and oil and gas fields. This coverage does not include glaciers or bathymetric data. 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 rock types, lithologic contacts, 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). Boundaries of polygons are not assigned attributes and are only indicators of the extent of rock distribution. This coverage is intended to serve as a base map and add geologic context to reported indications of petroleum in the Central Alaska province, as discussed in the accompanying report. The regional (1:2,500,000) scale of this coverage does not provide sufficient detail for site development purposes.
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 Kirschner's 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. All polygon features were digitized interactively by hand using ArcInfo.
