Abstract:
The Montana Geographic Names Framework (MGNF) holds names and locations for cultural and geographic featues in Montana. For most features, this is the Federally recognized name from the Geographic Names Information System (GNIS). This is intended to include the names of all features, current and historical, that are shown on maps, except for roads and highways.

The GNIS is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types.

The files available from the State Library include an ESRI feature class with the primary point and State-recognized official name of each feature. The distribution includes two additional tables. One contains the official names and additional alternate names for the features. The other has descriptions and historical information for certain features which the Board on Geographic Names or State Library staff have worked with.

The MGNF was developed from the Montana GNIS text file, the national all_names file, and the national feature description file dated October 1, 2016 that were available on the USGS web site at http://geonames.usgs.gov/domestic/download_data.htm. The State Library has performed extensive edits to the data, which are described in the Supplemental Information section of this metadata document.
Supplemental information:
Each feature is represented in the Montana Geographic Names Framework (MGNF) feature class by its "primary point". A geographic feature may have only one primary point regardless of size or extent. The primary point of a linear feature depends on the feature class. If feature class equals stream, valley or arroyo, the primary point is the mouth. The primary point of a canal, channel, or trail is the center. The primary point of an areal feature is the approximate geographic center with the following exceptions: The primary point of a populated place is the center of the original place, if known, such as the city or town hall, main post office, or town square regardless of changes over time. The primary point of a reservoir may be the center of the dam that impounds it. The primary point of a summit, range, ridge, or pillar is the highest point. These points do not represent feature boundaries or geometries and should not be confused with them.

The GNIS contains over 20,000 un-named wells, mines, and springs that have been deleted from the MGNF.

The GNIS contains many features that are partially in Montana, but whose primary coordinates are outside of the state. In the MGNF, the coordinates have been moved to the nearest appropriate location on the state boundary.

Before 2005, features in the GNIS were assigned elevations if the GNIS staff noted an elevation printed on a topographic map. The current GNIS from USGS has an elevation for every feature, estimated from the National Elevation Dataset. In the MGNF, the estimated elevations have been replaced by the old map-based GNIS elevations where they were available. Additionally, many elevations, especially of mountain peaks, have been replaced by the elevations printed on 1:24,000 scale topographic maps.

The MGNF has many corrections in the names, feature classes, and locations of features that have been noted at the State Library. The MGNF features contain a value in the Change_Log field that indicate what sorts of edits have been performed on them.

The State Library and Montana Fish, Wildlife, and Parks (FWP) cooperated in 2012 to synchronize the GNIS with FWP's property database, which includes state parks, wildlife management areas, and fishing access sites. Scores of FWP properties which were not in the GNIS have been added to this data set, and the GNIS_ID field has been arbitrarily assigned values less than zero.

Access constraints: None
Use constraints:
While this data set is useful for locating features, it is not intended to locate what features are near a location or within a given area. Large features such as streams and national forests are represented here by a single point, and the absence from the Montana Geographic Names Framework of a point for a feature in any area does not mean the feature is not in that area.

Attribute label: GNIS_ID
Attribute definition:
This is the unique Feature_ID assigned to the feature by the GNIS.

This number is assigned by the Geographic Names Information System and used as a relational key for uniquely identifying, indexing, and searching geographic features and for integrating or reconciling GNIS data with other data sets. The number has no information content. The GNIS Feature ID supersedes the Federal Information Processing Standard (FIPS) 55 Place Code as the Federal standard unique feature identifier and is under consideration as an ANSI standard.

Features with negative ID numbers have been added to the database by the State Library and are not in the national GNIS.

Attribute label: Name
Attribute definition:
Official Feature Name. If a feature has a 1 in the ten thousands column of the Change_Log field, the name was edited by the State Library.

Attribute label: Class
Attribute definition:
The GNIS has 66 types that a feature may be classified as. 58 of these classes occur in this file for Montana. If a feature has a 1 in the hundreds column of the Change_Log field, the feature has been reclassified at the State Library.

Attribute label: County
Attribute definition:
County that the primary GNIS location of the feature is in.

This is the value recorded in the national GNIS file. It may be incorrect if the State Library has moved the primary point.

Attribute label: Latitude
Attribute definition:
Latitude of the feature's primary point. If the feature is a stream, this is usually the coordinate of the mouth of the stream. If the value of the Change_Log field has a 1 in the ones column, this feature was moved from outside of Montana to the state boundary. If the value of the Change_Log field has a 1 or a 3 in the tens column, the location of the feature was edited by the State Library.

Attribute label: Longitude
Attribute definition:
Longitude of the feature's primary point. If the feature is a stream, this is usually the coordinate of the mouth of the stream. If the value of the Change_Log field has a 1 in the ones column, this feature was moved from outside of Montana to the state boundary. If the value of the Change_Log field has a 1 or a 3 in the tens column, the location of the feature was edited by the State Library.

Attribute label: Source_Lat
Attribute definition:
Latitude of the feature's upper end. This is blank for most features other than streams and valleys. If the value of the Change_Log field has a 2 or a 3 in the tens column, the location of the source was edited by the State Library.

Attribute label: Source_Lon
Attribute definition:
Longitude of the feature's upper end. This is blank for most features other than streams and valleys. If the value of the Change_Log field has a 2 or a 3 in the tens column, the location of the source was edited by the State Library.

Attribute label: Elevation
Attribute definition:
Elevation of the feature in feet. This elevation may be an estimate from the National Elevation Dataset, it may be from the 2002 GNIS, or it may be an elevation recorded from a topographic map. The value of the Change_Log field will have a 1 in the thousands place if the elevation was noted as being printed on a 1:24,000 scale topographic map, a 2 in the thousands place if the elevation was estimated by examining the feature location on a 1:24,000 scale topographic map, or a 4 in the thousands place if the elevation was copied from the 2002 GNIS. The elevation source of the 2002 GNIS is believed to be the largest scale topographic map that was available when the feature was entered into the GNIS in the 1980s, which may have been a 1:100000, 1:62500, or 1:24000 scale map.

Attribute label: Map_Name
Attribute definition:
Name of the 1:24,000 scale topographic map that the GNIS location of the feature is in.

This is the value recorded in the national GNIS file. It may be incorrect if the State Library has moved the primary point.
