Originator | Minnesota DNR - Minerals Division/Section of Wildlife
Title | Hybrid County Boundaries
System Name | ctybdne2
Abstract | Minnesota county boundaries derived from a combination of 1:24,000 scale PLS lines, 1:100,000 scale TIGER, 1:100,000 scale DLG, and 1:24,000 scale hydrography lines. At the time of its development (1993), the largest available scale data were assembled to create the layer.
Purpose | This layer exists to facilitate integration between county and PLS data sets. Used also as the basis for county-based tiling schemes with DNR's GIS Core datbase. The state border contained within the layer is used in numerous DNR data sets.
Time Period of Content Date | Unknown
Currentness Reference | A multitude of source dates are associated with this data set, including those associated with the original GISMO, RKI, DLG, and TIGER data set development efforts. Work on the coverage was completed during the summer/fall of 1993. Attribute restructuring to ensure conformance with DNR PLS Coding standard performed in March 1996.

Associated Data Sets | This coverage provided the county boundaries for the clipped (on county) version of the Section Level PLS Boundary coverage. The ctybdne2.lut table within the coverage provides a very useful cross-reference to the various county naming/number schemes used throughout the states GIS data holdings.
Section 2 | Data Quality Information - - - - - - top
Attribute Accuracy | Unknown
Logical Consistency | Data are topolocially correct using ARC/INFO 7.0.3. All polygons are closed and lines intersect where intended.
Completeness | All Minnesota county lands are present, including off-shore islands in Lake Superior. The official state and international borders within Lake Superior are not included in this data set.
Horizontal Positional Accuracy | Unknown
Vertical Positional Accuracy | Not Applicable
Lineage | County boundaries dissolved from 1:24,000 scale PLS coverages with non-coincident boundaries supplied by TIGER. Lake Superior North Shore boundary extracted from 1:100,000 scale USGS Digital Line Graph (DLG). PLS data source was derived primarily from GISMO coordinates, which were digitized from USGS 7 1/2 Minute Quadrangle maps. River Kilometer Index (RKI) features were used in the PLS coverage for irregular boundaries defined by Streams and rivers. TIGER source data was 1990 vintage. Some attribute table restructuring was performing during the GIS Core Library development effort in March 1996. This entailed bringing in selected fields from the county cross-reference table, including county names and county abbreviations.
