Abstract:

This layer contains 3.75-minute quadrangles (each of which covers one quarter of a U.S. Geological Survey 7.5-minute topographic map) for Montana, Idaho, and Wyoming. The feature attributes include the status of the State Library's digital Orthophoto holdings and USGS quadrangle names. These boundaries show the NAD83 location of the graticule lines, rather than the NAD27 lines that form USGS quadrangle boundaries.

Purpose: USGS quarter-quadrangles for Montana, Idaho, and Wyoming

Entity and Attribute Information:

Entity type label: quads_quarter_24k

Entity type definition: Point feature class

Attribute label: FID

Attribute definition: Shapefile sequence number

Attribute label: Shape

Attribute definition: Feature geometry

Attribute label: AREA

Attribute definition: Area of quarter-quadrangle in square meters

Attribute label: PERIMETER

Attribute definition: Perimeter of quarter-quadrangle in meters

Attribute label: DOQIDX_

Attribute definition: Sequence number from original coverage version of the data

Attribute label: NAME

Attribute definition:

Name of the USGS 7.5 minute quadrangle that contains this quarter-quadrangle

Attribute label: CODE

Attribute definition:

Numeric 7.5-minute quadrangle code of the quadrangle that contains this quarter-quadrangle

Attribute domain:

The first two digits are the latitude, and the next three digits are the longitude, of the nearest whole degree to the south and west of the quadrangle. The sixth and seventh digits are the row and column number (1-8) of the 7.5-minute quadrangle within the 1x1 degree latitude/longitude block.

Attribute label: QUARTER

Attribute definition:

Quarter-quadrangle (3.75-minute) identifier -- NE, NW, SE, or SW

Attribute label: DATE

Attribute definition:

Date of the first generation U.S. Geological Survey digital orthophoto quarter-quadrangle image of the area held at the State Library. The earliest images are from 1990 and the latest are from 2003. The date is set to 1/1/1800 for quadrangles the Libray has no image for.

Attribute label: DOQQSTATUS

Attribute definition: Status of the State Library quarter-quadrangle orthophoto.

Attribute Value Definition of Attribute Value -1 The quadrangle is outside of Montana and the availability is not known 0 The digital orthophoto quarter-quadrangle is not available 3 The digital orthophoto quarter-quadrangle is available at the State Library 4 The digital orthophoto quarter-quadrangle is available at the State Library 5 The digital orthophoto quarter-quadrangle is available from the US Geological Survey, but not at the State Library

Attribute label: STATE

Attribute definition: Single-character State code

Attribute domain:

Any quarter-quadrangle that touches Montana has a code of M. Other quadrangles are coded I, U, or W depending on whether they are primarily in Idaho, Utah, or Wyoming. Codes for these other states are un-reliable -- check the STATECODE field

Attribute label: STATECODE

Attribute definition:

List of two-letter state abbreviations for all states touched by the 7.5-minute quadrangle

Attribute domain:

I believe these codes are derived from the states touched by the ENTIRE quadrangle that each quarter-quad is part of. The states are listed in order of how much area they cover in the quadrangle

Attribute label: DARKIMAGE

Attribute definition: DARKIMAGE

Attribute Value Definition of Attribute Value -9999 No digital orthophoto quarter-quadrangle is available 0 The digital orthophoto quarter-quadrangle image has no black pixels, or the image is not available 1 The number of black pixels in the digital orthophoto quarter-quadrangle image is not known Numbers greater than 1 Number of black pixels

Attribute label: SPC_SID

Attribute definition: State-Plane Coordinate MrSID image status

Attribute Value Definition of Attribute Value 0 The State Library does not have a MrSID version of this image in State Plane Coordinates 1 The State Library has a MrSID version of this image in State Plane Coordinates 2 This quarter-quadrangle is entirely covered by a lake and is not available

Attribute label: SPC_TIFF

Attribute definition: State-Plane Coordinate TIFF image status

Attribute Value Definition of Attribute Value -1 The State Library does not have this image and it is outside of Montana 0 The State Library does not have this image and it is inside or close to Montana 1 or 2 This image is available at the State Library. There are two possible values because the images were formerly stored on two different disk systems.

Attribute label: UTM_SID

Attribute definition: UTM Coordinate MrSID image status

Attribute Value Definition of Attribute Value 0 The State Libary has not made a UTM MrSID image of this quadrangle 1 A UTM-Coordinate MrSID image of this quadrangle is available at the State Library 2 This quarter-quadrangle is entirely covered by a lake and is not available

Attribute label: UTM_BSQVOLNUM

Attribute definition:

Tape volume number of the DLT tape the State Library received this image from the US Geological Survey on. If the number is zero, the State Library received this image on CD or does not have it.

Attribute label: TAPECODE

Attribute definition:

This is the code the US Geological Survey used to identify the quadrangle on DLT tape.

Attribute domain:

This is similar to the CODE value, except that the last two digits are a sequence number (01-64), counted left to right, top to bottom, in the 1x1 degree latitude/longitude block.

Attribute label: DOQQYEAR

Attribute definition:

This is the year of the digital orthophoto quarter quadrangle photograph
