Pierce in 1982. The map along with other map data was assembled into the geologic map of the Cody 2-degree quadrangle, Wyoming at a a scale of 1:250,000. Both the National Geologic Map Database and the Greater Yellowstone Science Initiative needed digital geologic map data adequately attributed for many kinds of analysis. The accompanying database conforms the the preliminary North American geologic map datamodel Revision 4.3. Attributes attached to each polygon include a dataset id, a source id and a classification object id (cls_obj)id). For polygons,the classification object id is linked to the rest of the database to qualify polygons with a rock unit code, rock unit name name, a standard lithology, formation age, other miscellaneous data. For lines, the classification onject id is linked to the rest of the database to qualify lines with structure type, location accuracy, and certainty of existence. Purpose: The conversion of bedrock geology information of the map into a digital format enables easy overlay with other layers for analysis and development of other themes. Use at a scale larger than 1:50,000 is not recommended.

Pierce in 1982. The digital version has been checked visually for consistency with the original materials. All polygons and lines have attributes that reflect the values on the compilation materials. Logical_Consistency_Report: The dataset was checked by comparing check plots with the original maps. Map elements were checked visually for overshoots, undershoots,duplicate features, polygon closure, and other errors by the author. In Addition, automated (ARC/INFO) routines were used used to check for polygon label errors, line attribution errors, sliver polygons, dangling arcs, intersection errors and projection information. Completeness_Report: The dataset included all possible information from the compilation materials for use at a scale of 1:100,000. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The original data was probably accurate to within 50 meters. This map can be no better than National Map Accuracy standards.

Process_Step: Process_Description: The original materials were scanned at 400 dots-per-inch on an Anatech optical scanner. The scan was saved as a 256-level gray-scale TIFF image. The TIFF image was "cleaned up" in Adobe Photoshop (TM). The TIFF image was changed to a bit-mapped image and changed to an RLC file. The RLC file was georeferenced and autovectorized in LT4X, a commercial software package. The resulting vectors were cleaned up in ARC/INFO and built into a polygon coverage. The attributes were then added. The original scanned image after registration to the coverage was used as a backdrop to constantly check the coverage for accurcay of line placement as well as attribution of the polygons and lines. The ARC/INFO coverage was then converted to ARCVIEW shape files and associated DBASE (DBF) files.
