Abstract:
These are the 60x30 minute, 1:100,000 scale, quadrangles of Montana. The layer contains attribute fields for the quadrangle names and dates of various map and data products related to the quadrangles that have been available from the State Library. The data coordinates are in the North American Datum of 1983, but the quadrangle lines follow the meridians and parallels of the North American Datum of 1927. These lines may be up to 100 meters from the meridians and parallels of modern geographic coordinate systems.

Attribute label: Pub_Date
Attribute definition:
Publication year of the USGS 1:100,000 scale map that is in the State Library's scanned Digital Raster Graphic (DRG) collection

Attribute label: SourceDate
Attribute definition:
Year shown on the State Library's DRG image as the date of the 1:24,000 scale maps that the 1:100,000 scale map was compiled from

Attribute label: MetaDate
Attribute definition:
Year from the "Time Period of Content" date in the metadata file that came from USGS with the DRG image.

Attribute label: USGSCode
Attribute definition:
USGS latitude-longitude quadrangle code. This code consists of two digits for the latitude and three digits for the longitude of the southeast corner of the latitude/longitude block that the quadrangle is in. The sixth and seventh digits are "a1" if the quadrangle is the south half of the block or "e1" if the quadrangle is the north half of the block.

Attribute label: MapAngle
Attribute definition:
This is the counter-clockwise angle between grid north in the Montana State Plane coordinate system and true north at the center of the quadrangle. This value was used by the State Library to produce maps of the quadrangle in State Plane coordinates that were oriented with true north, rather than grid north, being vertical.

Attribute label: HYDRO

The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing hydrographic features digitized from the 1:100,000 scale topographic maps. This is the publication date of the hydrography file for this quadrangle.

Attribute label: Road
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing roads digitized from the 1:100,000 scale topographic maps. This is the publication date of the roads file for this quadrangle.

Attribute label: Rail
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing railroads digitized from the 1:100,000 scale topographic maps. This is the publication date of the railroads file for this quadrangle.

Attribute label: Misc
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing miscellaneous transportation features digitized from the 1:100,000 scale topographic maps. This is the publication date of the misc transportation file for this quadrangle.

Attribute label: USPLS
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing U.S. Public Land Survey features digitized from the 1:100,000 scale topographic maps. This is the publication date of the public land survey file for this quadrangle.

Attribute label: Bound
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing administrative boundaries digitized from the 1:100,000 scale topographic maps. This is the publication date of the boundary file for this quadrangle.

Attribute label: Contour
Attribute definition:
The US Geological Survey produced a series of vector Digital Line Graph (DLG) GIS data files showing land surface contour lines digitized from the 1:100,000 scale topographic maps. This is the publication date of the contour line file for this quadrangle.

Attribute label: Perimeter
Attribute definition: perimeter of the polygon in meters

Attribute label: Area
Attribute definition: area of the polygon in square meters
