Map of Montana's 7.5-minute quadrangle names
Abstract:
These data show the boundaries of the 1:24,000 scale, 7.5-minute USGS topographic maps of Montana. The polygon boundaries follow meridians and parallels of the NAD27 latitude-longitude lines that formed the boundaries of the 20th-century paper maps. All quadrangles that intersect Montana or that touch a quadrangle that intersects Montana have been included.Each polygon has fields for the map name and for four different ID code systems that have been used for the quadrangles. There is a field that shows the published year of the 1:24,000 scale topographic map that the Montana State Library has an image of.
Purpose:
1:24K scale Quadrangle Boundaries for Montana
Time period of content:
Beginning date:
1998
Ending date:
2013
Currentness reference:
Quadrangle dates were established in 1998. Map names were updated in 2013 to reflect the eliminaiton of "Squaw" names from geographic features in Montana.

Name
Attribute definition:
USGS 1:24,000 scale map name. Where map names have changed, the old name is included in parenthesis. Quadrangles in Canada do not have names.
Attribute label:
QCode_Text
Attribute definition:
This is a code for the quadrangles where the first five characters give the integer parts of the latitude and longitude of the quadrangle southeast corner, the sixth character is in the range "a" through "h" to indicate how many rows north the quad is from the whole latitude/longitude corner, and the seventh character is a number 1 through 8 to indicate how many columns west the quand is from the corner.
Attribute label:
QCode_RC
Attribute definition:
This is a code for the quadrangles where the first five characters give the integer parts of the latitude and longitude of the quadrangle southeast corner, the sixth character is a number 1 through 8 to indicate how many rows north the quad is from the whole latitude/longitude corner, and the seventh character is a number 1 through 8 to indicate how many columns west the quand is from the corner.
Attribute label:
QCode_Seq
Attribute definition:
This is a code for the quadrangles where the first five characters give the integer parts of the latitude and longitude of the quadrangle southeast corner. The sixth and seventh digits are a sequence number counting left to right and top to bottom from the northwest corner of the 1x1 degree quadrangle block.
Attribute label:
CivilAirID
Attribute definition:
Civil Air Patrol Grid Designation. This consists of a three-character code designating which NOAA sectional aeronautical chart the quadrange is in, a three digit sequence number for 15-minute quadrangles, and a character "A" through "D" indicating which corner of the 15-minute quad the 7.5-minute quadrangle is in.
Attribute label:
UTMZone
Attribute definition:
Universal Transverse Mercator coordinate zone that the quadrangle is in
Attribute label:
States
Attribute definition:
Comma-delimited list of abbreviations of the states and/or provinces that the quandrangle covers
Attribute label:
MSL_Date
Attribute definition:
Published year of the 1:24,000 scale topographic map that the Montana State Library has an image of. These quadrangles were obtained in 1998 and all of the dates are earlier than that.
