Bush Publication_Date: 200512 Title: Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands Edition: 1.0 Geospatial_Data_Presentation_Form: Map Publication_Information: Publication_Place: Denver, CO Publisher: U.S. Geological Survey Online_Linkage: Description: Abstract: This data set contains boundaries and tags for major geologic units in Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands. In addition to the polygons representing the areal extent of geologic units, it identifies major faults and continental glaciation in Alaska. The data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. This map complements the Generalized Geologic Map of the Conterminous United States by Reed and Bush. The data are generalized from a compilation prepared for use in the Geologic Map of North America, published as a paper map by the Geological Society of America and to be released as a digital file by the U.S. Geological Survey. Purpose: These data have been prepared with a degree of detail appropriate for viewing at a scale of 1:7,500,000. Because of the degree of generalization required (generalization based on compilation scale), the data are intended primarily for display and for regional and national analysis, rather than for more detailed analysis in specific areas. No responsibility is assumed by the U.S. Geological Survey in the use of these data. Supplemental_Information: The data set for the Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands consists of four data layers. All the data layers were created as ArcInfo coverages and converted to other formats for distribution purposes. The data layers are distributed and should be used together. The data are available as shapefiles or ArcInfo Export files. The data layers for faults are included in two different versions. The following files are included: > fltg01l075 - Fault lines, with line decorations* > falt01l075 - Fault lines, without line decorations** > geol01m075 - Geologic units, as polygons > gtxt01l075 - Graphic representation of geologic unit text* > >* These files are not 'true' ArcInfo coverages; they are graphic > representations of symbols and text used on the geologic map. These > files should be used to produce appropriately symbolized graphics. > The decorations and text appear correctly only in Lambert Azimuthal > Equal Area projection. The parameters for the projection are: > Projection Lambert Azimuthal Equal Area > Datum NAD83 > Spheroid GRS1980 > Units Meters > Radius of the sphere of reference 6370997 > Longitude of center projection -100 > Latitude of center of projection 45 > >**This file is the same as the fault file marked with * but does not > include the line decorations. This is the 'true' ArcInfo line > coverage for faults. This file should be used for data analysis. Also distributed with the data is the shadeset, geoshade.shd. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, some ArcInfo- specific terminology is included for clarity and expediency.

The plots were then compared to the source. The polygon attributes were checked by visually comparing the final colored plots to maps at various larger scales. Logical_Consistency_Report: Polygon and node topology are present. All polygons are labeled and were tested by using the ArcInfo command LABELERRORS. All polygons were checked for closure, node errors, overshoots, undershoots, dangles and intersections using ArcInfo routines. The ArcInfo commands BUILD and CLEAN were run to ensure the topological consistency of the data set. Completeness_Report: This data set contains map unit boundaries and codes for Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands. Boundaries and codes are included for geologic units and major faults. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The accuracy of the original data was checked by comparing the digital files to several data sources. Both the line work and the polygon labels were checked against the source compilation.

The layer was projected to match the polygon and line coverages created from the compiled scans. Data for the conterminous United States were deleted. Single-line streams were deleted from Alaska, Hawaii, Puerto Rico and the U.S. Virgin Islands. Remaining rivers, glaciers, and shorelines were added to the geologic unit coverage. Contacts were modified where they intersected with shorelines, and the new lines and polygons were attributed.

Fltg01l075 is the same as falt01l075, except decoration lines have been added. Gtxt01l075 contains arcs that represent text labels for the geologic unit polygons. These coverages were created by exporting the geologic unit and fault coverages to ASCII files which were then imported into the program GSMCAD, written by Van S. Williams, USGS. GSMCAD was used to export the files in Generate format and to create ArcInfo coverages with the decorated fault lines and the arcs for polygon labels. GSMCAD is available at no charge at .
