Staff, DGGS, 2002, Geologic map of the Dalton Highway (Atigun Gorge to Slope Mountain) area, southern Arctic Foothills, Alaska - vectorized topographic dataset: Preliminary Investigative Report PIR 2002-2, State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (DGGS), Fairbanks, AK, USA.
Planar coordinates are encoded using coordinate pair
Abscissae (x-coordinates) are specified to the nearest 0.000128
Ordinates (y-coordinates) are specified to the nearest 0.000128
Planar coordinates are specified in meters
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6,378,206.4.
The flattening of the ellipsoid used is 1/294.98.
|Range of values|
|null||polygon is a water body|
|non||polygon is a landmass|
|0||corresponds to unlabeled hypsographic contour lines or to hypsographic contour lines that exist outside of the geologic map area|
|Range of values|
|point||spot elevation data point|
|lake||lake elevation data point|
|bench||benchmark elevation data point|
|0||corresponds to unlabeled data points that are either erroneous or that exist outside of the geologic map area|
|Range of values|
Three of these data points exist within the geologically mapped area, their values are “Gal”, “Knit”, and “Lake”.
Values in this field are self explanatory text terms that describe each feature.
Funding for the geologic mapping and geochronologic dating performed for this project was provided by the U.S. Geological Survey STATEMAP Program under award number 03HQAG0055 and by the Alaska State Legislature. Project management by E.E. Harris. Digital attributing and metadata by: Simone Montayne and Paige Peaples. Edited by: Paula K. Davis and Carrie Browne

This topographic dataset supplements the geologic report, PIR 2002-2, Geologic map of the Dalton Highway (Atigun Gorge to Slope Mountain) area, southern Arctic Foothills, Alaska. The dataset was obtained and attributed to enhance the print quality of paper version of the geologic report. It is intended as an add-on to the geologic vector data distribution package.

Data sources used in this process:
Spatial data attributes were attached to data objects using ArcGIS 8.1. Attributes within the geologically mapped area were verified for consistency and completeness during the creation of the metadata. Entities and attributes that occur or extend beyond the geologic map boundary have not been quality controlled for completeness or accuracy.
Individual mylar map separates were scanned and digitized to Alaska Division of Geological & Geophysical Surveys (DGGS) specifications, error magnitude associated with this step is unknown but is assumed to be small or non-existent relative to possible errors in the associated geologic dataset.
This dataset includes data tables that contain information about hydrologic, hypsographic, cultural features.
Topology is present on appropriate polygon and line datasets; others are point data.
