Supplemental Information

This digital data distribution package provides shapefiles and geodatabase that portray features presented in RI 2017-10. Field names and values are organized according to the NCGMP09 - Draft Standard Format for Digital Publication of Geologic Maps, Version 1.1 by the USGS National Cooperative Geologic Mapping Program (NCGMP). This metadata file lists the table names and field names used in the geodatabase. Table and field names in the shapefiles are truncated at 10 characters. The geodatabase and selected shapefiles provide the following features:
 >Basemap: Geodatabase feature dataset that provides topographic contours, hydrology, and geographic place names
 >CorrelationOfMapUnits: Geodatabase feature dataset that depicts the map unit correlation chart; includes applicable unit designators, brackets, dividing lines, and text
 >ContactsAndFaults: Line features that depict faults and geologic contacts
 >DataSourcePolys: Polygons that delineate the data sources for various parts of the map
 >DataSources: Non-spatial reference table that provides bibliographic references for the datasets or information used to generate or interpret geologic or geographic features
 >DescriptionOfMapUnits: Non-spatial reference table that provides key information about each map unit. Additional information may be found in an accompanying report.
 >GenericPoints: A point file that provides locations and labels for key geologic features or observations.
 >GeochronPoints: Geochronology sample location points.
 >GeologicLines: Dikes, coal seams, ash beds, glacial features, anticline and syncline hinge-surface traces, and other kinds of key beds that do not participate in map-unit topology
 >MapUnitPolys: Polygons that record the distribution of mapped or interpreted geologic units
 >OtherPolys: Polygons that record the location and extent of geologic or geographic features other than the geologic units
 >RepurposedSymbols: Non-spatial reference table that documents cases in which FGDC Standard symbols are supplemented with custom symbols or with FGDC symbols repurposed for the map.
 >Stations: Field observation locations and descriptions
