The data release for the geologic and structure maps of the Kalispell 1 x 2 degrees quadrangle, Montana, and Alberta and British Columbia, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-2267 (Harrison and others, 2000). The updated digital data present the attribute tables and geospatial features (lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plates and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version.
The database represents the geology for the 16,436 square kilometer, geologically complex Kalispell 1 x 2 degrees Quadrangle, at a publication scale of 1:250,000. The map covers primarily Flathead and Lincoln Counties, but also includes minor parts of Glacier, Lake, and Sanders Counties. These GIS data supersede those in the interpretive report: Harrison, J.E., Cressman, E.R., Whipple, J.W., Kayser, H.Z., Derkey, P.D., and EROS Data Center, 2000, Geologic and structure maps of the Kalispell 1:250,000 quadrangle, Montana, and Alberta and British Columbia: a digital database: U.S. Geological Survey Miscellaneous Investigations Series Map I-2267, version 1.0, 23 p., scale 1:250,000, https://pubs.usgs.gov/imap/i2267/.
The purpose of the data release is to produce a Geologic Map Schema (GeMS)-compliant version for the geologic and structure maps of the Kalispell 1 x 2 degrees quadrangle, Montana, and Alberta and British Columbia, that updates the geospatial data published as part of U.S. Geological Survey Miscellaneous Investigations Series Map I-2267 (Harrison and others, 2000). Conversion and publication of the geologic map in modern GIS format (e.g. ArcInfo coverages converted to ArcGIS geodatabases) is considered to be foundational and high-priority by the Mineral Resources Program to facilitate ongoing research and other activities by USGS Mineral Resources Program pertaining to critical mineral deposits as well as to other geologic mapping, petrologic studies, and mineral resource assessments. The data reside in the National Geologic Map Database (NGMDB) distributed archive of standardized geoscience information for the nation.
This dataset conforms to the Geologic Map Schema (GeMS) standard for geologic map publications: https://doi.org/10.3133/tm11B10 and consists of these files and folders:
Kalispell_1x2degree-gdb.zip: a zip archive containing the map geodatabase and other elements of the digital data package:
Kalispell_1x2degree.gdb: an Esri file geodatabase – see below for explanation of feature classes and tables.
Kalispell_1x2degree.mxd: an Esri ArcMap exchange document.
Kalispell_1x2degree-metadata: a folder containing the metadata in various formats.
Kalispell_1x2degree-metadata-datadict.csv: a data dictionary of all fields in the database.
Resources: a folder containing an Esri style file (Kalispell_1x2degree.style) that contains the area, line, and point symbols used to symbolize the map and Federal Geographic Data Committee (FGDC) symbol font files.
Kalispell_1x2degree-open.zip: a zip archive containing the shapefile versions of the database and TXT (text) and CSV (comma-separated values) versions of tables; Kalispell_1x2degree-metadata-datadict.csv; and the Kalispell_1x2degree-metadata and Resources folders. Note that attribute field names in the shapefiles are limited to 10-characters; a text file (logfile.txt) lists equivalent field names between the geodatabase and the shapefiles. The schema.ini file is provided to assist proper import of CSV tables into software. It is recommended that TXT tables be imported with all fields specified as data type “text”.
The Esri file geodatabase (Kalispell_1x2degree.gdb) contains the following elements:
GeologicMap: feature dataset (subdirectory) containing the following feature classes (GIS layers):
ContactsAndFaults: line layer representing locations of contacts and faults.
DataSourcePolys: polygon layer representing the spatial extent of data sources and (or) references used within the map boundary.
GeologicLines: line layer representing the locations of dikes, fold axes, and other linear features.
MapUnitPolys: polygon layer representing the distribution of geologic map units.
DataSources: table that lists sources and (or) references used to derive spatial features (lines and polygons) and attribute information.
DescriptionOfMapUnits: table of map unit descriptions derived from the collar of the geologic map or geologic map pamphlet. The hierarchical order of map units is coded in the HierarchyKey field.
GeoMaterialDict: table that defines and lists lithology terms in hierarchical order used in the GeoMaterial field of the DescriptionOfMapUnits table. The standardized vocabulary is available in Appendix 1 of the GeMS documentation, available at https://doi.org/10.3133/tm11B10.
Glossary: table that defines and lists sources of terms used in the database.

Work was accomplished by the U.S. Geological Survey Geology, Geophysics, and Geochemistry Science Center (GGGSC) with support from the Mineral Resources Program (MRP) and the National Geologic Map Database (NGMDB).
Microsoft Windows 10 Enterprise, Version 10 (Build 18363); Esri ArcGIS 10.8.1.14362
Unique values in attribute fields were checked through frequency analyses. The unique values in each attribute field were reviewed and checked for spelling, consistency of terms, accuracy, adherence to established vocabularies, and completeness. Text terms and values entered by USGS authors were reviewed and verified.
GIS layer and attribute information were cross walked into the GeMS database structure. Attribute values were modified for consistency with GeMS terminology. Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data.
The original GIS database (Harrison and others, 2000) was converted from ArcInfo interchange files (E00) to an Esri file geodatabase. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The data set is considered complete for the information presented and as described in the abstract.
Horizontal accuracy of point, line, and polygon features is dependent on the source data. Computing technologies used for original data capture resulted in variable line quality and accuracy. Consequently, estimated accuracy of horizontal location, given on a per-feature basis by attribute LocationConfidenceMeters in GeMS, was assigned a value of -9 indicating unknown. Base maps and/or materials used for original data capture (ArcInfo coverages) are no longer available. Registration discrepancies between the printed map and the digital data are not addressed in this version.
Vertical accuracy testing does not apply to this dataset.

Standardized geologic map symbolization used for symbolizing the map.
Harrison and others (1992) compiled the geology and published the original geologic paper map at 1:250,000 scale. The geologic map was scanned, digitized, and prepared as ArcInfo coverages by EROS Data Center prior to 1994. The data were later converted to topologically correct ArcInfo coverages, attributed, and published by Harrison and others (2000).
Harrison and others (1992)
2000
The original data were converted from ArcInfo interchange files (E00) format into feature classes within an Esri file geodatabase. Attributes were standardized to conform to the Geologic Map Schema (GeMS) standard for geologic map publications: https://doi.org/10.3133/tm11B10. GeMS geodatabase feature classes and tables were populated with additional information as required. Data layers were re-projected to Albers Equal Area, North American Datum 1983, in units of meters.
Topology tests were conducted on polygon and line feature classes to ensure spatial integrity of the data.
Base maps and (or) materials used for original data capture are no longer available, therefore a georeferenced version of the original map publication (https://ngmdb.usgs.gov/Prodesc/proddesc_10204.htm) from the National Geologic Map Database was used to compare attribute information and to correct minor discrepancies between the GIS data and the printed map. Minor errors, such as differences in line decoration, line type, or map units were corrected and documented in the Notes attribute field. Registration discrepancies between the printed map and the digital data are not addressed in this version.
Map unit colors were matched to the original publication as best possible and are represented as RGB values in the AreaFillRGB field of the DescriptionOfMapUnits table. They are also provided in the custom Esri Style file.
Geologic map symbolization was matched to the original publication as best possible using the FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC, 2006). These values are represented in the Symbol attribute fields and are provided in the included Esri Style file.
The 'Index to Sources of Geologic Data' index map shown on the printed map was digitized and included in the DataSourcePolys polygon layer and DataSources table as a courtesy. These are the sources used to produce the original printed geologic map; they are not the sources used to produce the original GIS data (DAS01).

Source (DataSources)
Plain-text short description that identifies the data source.
GeMS (2020)
Example of values: "Whipple, 1984, scale 1:48,000"
Symbol (DescriptionOfMapUnits, ContactsAndFaults, GeologicLines, MapUnitPolys)
Reference to a point marker, line symbol, or area-fill symbol that is used on the map graphic to denote the feature: perhaps a star for a K-Ar age locality, or a heavy black line for a fault.
GeMS (2020)
Numbers correspond to FGDC symbolization or a MapUnit. These values also correspond to the supplied Style file. Examples of values: "02.02.07" or "Ysw"
Term (Glossary)
Plain-language word for a concept. Values must be unique within database as a whole.
GeMS (2020)
Values correspond to attributes primarily used in the Type fields. Example of values: "syncline, double plunging"
Type (ContactsAndFaults, GeologicLines)
Classifier that specifies what kind of geologic feature is represented by a database element: that a certain line within feature class ContactsAndFaults is a contact, or thrust fault, or water boundary.

anticline
A fold, generally convex upward, whose core contains the stratigraphically older rocks.
Neuendorf and others (2011)
anticline, overturned
A fold, generally convex upward, whose core contains the stratigraphically older rocks that has tilted beyond the perpendicular.
