Title Minnesota River Basin 7 1/2 Minute Quadrangle Index (MRBQ024)
Abstract Mathematically generated grid representing USGS 7 1/2 Minute Quadrangle Map outlines. Quadrangle names and standard identifiers are included with the data set.
Purpose To provide a standard framework for 1:24,000 scale basemap.
Time Period of Content Date 5/16/1993
Currentness Reference Much of the original processing was performed in 1991. The current version corrects problems identified in the February 1992 version. Attribute restructuring in March 1996.

Data Quality Information - - - - - - Go back to top
Attribute Accuracy Unknown
Logical Consistency Data are topologically correct within ArcInfo 7.1.2. All polygons are closed and lines intersect where intended.
Completeness All 7 1/2 minute blocks that fall entirely or partially within the Minnesota River Basin are included.
Horizontal Positional Accuracy 0.1 Meter
Vertical Positional Accuracy Not applicable
Lineage This layer was created by using the ARC/INFO GENERATE command to generate a double precision rectangular grid in geographic (latitude/longitude) coordinates at a 7 1/2 minute interval. Attributes for Minnesota Quad ID codes and USGS Quadrangle name were then assigned by transferring attributes from an existing file of coordinates maintained at LMIC. The source attributes were tied to the lower left corner of each quad. By generating a point coverage from these coordinates and shifting the point positions to the northwest, label points for this coverage were effectively created. The coverage was then projected into UTM Zone 15. Several specialized attribute fields were dropped from the source polygon attribute table (.PAT) during the Core Database restructuring effort in March of 1996.
Source Scale Denominator 0
