This digital data distribution package provides ESRI ArcGIS .mxd file, geodatabase, and shapefiles that portray features presented in
RI 2016-5. 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:
>border: A polygon that encompasses the maximum geographic extent of the data observations.
>CorrelationOfMapUnits: Geodatabase feature dataset that depicts the map unit correlation chart; includes applicable unit designators, brackets, dividing lines, and text, NCGMP09 format
>CrossSection: Geodatabase feature datasets of geologic cross sections; includes applicable unit designators, brackets, dividing lines, and text, NCGMP09 format.
>CartographicLines: Cross section transects, NCGMP09 format.
>ContactsAndFaults: Line features and annotation depicting faults and geologic contacts, NCGMP09 format.
>CoveredUnitLabelsAnno: Annotation labels for covered map units.
>DataSourcePolys: Polygons that delineate the data sources for various parts of the map, NCGMP09 format.
>DikePoints: Dike location points, NCGMP09 format.
>FossilPoints: Fossil location points, NCGMP09 format.
>GeochronPoints: Geochronology sample location points, NCGMP09 format.
>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, NCGMP09 format.
>MapUnitPolys: Polygons and associated annotations that record the distribution of mapped or interpreted geologic units, NCGMP09 format.
>OrientationPoints: A point file that provides field station locations, symbology, and associated structure data (bedding attitudes, foliation attitudes, slip vectors measured at a point, etc.), NCGMP09 format.
>Stations: A point file that provides location information, observations, and other data specific to each field observation station, NCGMP09 format.
