Metadata created using Minnesota Geographic Metadata Guidelines


Metadata Summary

Originator Minnesota Department of Natural Resources - MIS Bureau
Abstract This is a mathematically generated grid in which each polygon represents one quarter of a standard USGS 7 1/2 minute quadrangle. The result is a 3 3/4 minute quadrangle layer which nests within the standard USGS quads and whose tile naming scheme includes reference to the parent quadrangles. Known as the 'Quarter Quad' coverage.

Title Quarter 7 1/2 Minute Quadrangle Index (Quarter Quad), Minnesota
Abstract This is a mathematically generated grid in which each polygon represents one quarter of a standard USGS 7 1/2 minute quadrangle. The result is a 3 3/4 minute quadrangle layer which nests within the standard USGS quads and whose tile naming scheme includes reference to the parent quadrangles. Known as the 'Quarter Quad' coverage.
Purpose To provide a standard framework for accessing and creating data sets tiled by 'quarter-quad.'

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Not specifically assessed
Logical Consistency All polygons are closed and lines intersect where intended.
Completeness All 3 3/4 minute blocks that fall entirely or partially within the state of Minnesota are included.
Horizontal Positional Accuracy Not assessed.
Vertical Positional Accuracy Not Applicable
Lineage Attributes were derived directly from the parent coverage (q024ine4). Each polygon was assigned the tile-name of the parent polygon, with the designation nw,ne,sw,se appended, depending on what quadrant of the original 7 1/2 minute quadrangle the polygon represented. Transfer of attributes was accomplished via AML programming at the same time as the cartographic representation was created.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview Tile_name: 4-digit 7 1/2 minute quad code used at the Land Management Information Center, preceded by a 'q' and followed by the directional quadrant identifier (e.g., q0911ne)

Quadrant: Directional quadrant identifier (e.g. SW)

Dnrcode: 4-digit 7 1/2 minute quad code used at DNR.

Qq_name: Full name of quarter quad tile, typically the seven and one-half minute quad name with directional quadrant identifier appended to it. A hyphen with a space before and after separates the quad name from the direction. E.g., Gatzke SW - NE

Doq_image: U.S. Geological Survey name for the DOQ image covered by that quarter-quad.

Doq_header: U.S. Geological Survey name for the header file associated with the DOQ image covered by that quarter-quad.
