It is used to create the map sheet in OFR 2013-1090, which shows geology at 1:250,000 scale. Purpose: Digital representation of geologic mapping facilitates the presentation and analysis of earth-science data. Digital maps may be displayed at any scale or projection, however the geologic data in this coverage is not intended for use at a scale larger than 1:250,000.

Native_Data_Set_Environment: Dataset was created using ESRI ARC/Info version 10.0. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: All vector features were originally hand digitized from a folded paper map using a large digitizing tablet , or from a scanned image on screen. The digital data has been visually checked and the geologic map has undergone technical review. Logical_Consistency_Report: Coverage lhgeol is a network coverage containing attributed arcs and polygons. Each polygon has a coded attribute designating the mapped geologic unit. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic contact, only a single arc is present. Dangle arcs may be present (faults, moraine, etc.) Completeness_Report: This coverage was used to create the map of OFR 2013-1090. Text files, tables, graphics, symbolsets, and topography shown on the map sheet are not included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Users of this digital geologic map should respect the intentions of the original mappers and the limitations of the map. This geologic map compilation is intended to be used at a scale of 1:250,000; it is not intended to be used at a more detailed scale. Lineage: Process_Step: Process_Description: All vector features were originally hand digitized on a large digitizing tablet from a folded paper map or on from a scanned image on screen. After digitizing, the arcs and polygons were attributed. The coverage is provided in UTM projection and geographic coordinates. The ARC/Info coverages have been exported to an interchange file format, .e00, and also converted to ArcView shape files. Note that unlike the coverages the shapefiles do not maintain topology between the arcs and polygons and the directions from start node to end node may have changed from the original coverage direction.

Table lhgeol.pat includes the following items: CLASS, MODIFIER, and LABEL (geologic unit label). NOTE: Because of the limitations of common GIS fonts, the letters "Pz" and "Tr" are substituted for the standard symbols "Paleozoic" and "Triassic." Entity_Type_Definition_Source: This dataset Attribute: Attribute_Label: CLASS Attribute_Definition: CLASS is a positive integer value (4 5 B) item in the polygon attribute table. Values range nonsequentially from 101 to 1705. Every unit listed in the description of map units has a unique CLASS value. Units that are queried are attributed with the same class value as the listed unit. Units queried where uncertain. Each CLASS value listed below is defined by the information from the LABEL (6 8 c) item which contains the geologic unit label if one was assigned.
