Associated Data Sets | landfln2 - contains a variety of cartographic symbols created using Autocad such as text leader lines, flow direction arrows, drumlins, lineations etc. |
Section 2 | Data Quality Information - - - - - - top |
Attribute Accuracy | The data were scrubbed for validity of codes and code combinations. Source materials were reviewed during the initial conversion process from Autocad to ARC/INFO for completeness and accuracy. |
Logical Consistency | Data are topolocially correct using ARC/INFO 7.0.3. All polygons are closed and lines intersect where intended. |
Completeness | Statewide coverage is available |
Horizontal Positional Accuracy | unknown |
Vertical Positional Accuracy | not applicable |
Lineage | This data set contains information derived from NHAP air photos (1:80,000), USGS 1:100,000 and 1:24,000 scale topographic maps and from a variety of source products related to surface geology. The data were developed by two separate parties, each under contract with the Minnesota Department of Natural Resources (DNR). The northern half of the state, delineated by latitude 96 degrees (except for the Grantsburg (q3142) and Lake Minnewaska (q3118) 100K sheets), were developed under the direction of Dr. Howard Mooers, at the Department of Geology, University of Minnesota-Duluth (UMD). All of the data south of this boundary were developed by the Minnesota Geological Survey (MGS) in St. Paul. The UMD-developed data were developed almost exclusively through review of existing map sources, especially topographic expression as a basis for delineating landforms. This part of the effort did not include a field survey component. The data were mapped to the USGS 1:100,000 scale base (sheets published in 1/2 by 1 degree blocks). These data were originally digitized in AutoCAD and later converted and processed in ARC/INFO. DNR conducted fairly extensive manual and automated data reviews during this process in ensure consistency in the product. The MGS data were also developed using the USGS 1:100,000 scale base from similar sources. However, in performing their work, MGS incorporated a variety of other data sources, including some that relied on field survey-verification of interpretations. The MGS work was performed entirely in ARC/INFO. DNR was the principal party responsible for the development and maintenance of a standard database design and valid codes lists, and coordinating the boundary reconciliation between the two mapping efforts. Once complete, all quads were edgematched and then merged into a single statewide coverage. This coverage underwent extensive data scrubbing to locate all errors across quad boundaries and also to verify non-valid geomorphic codes and code combinations. Corrections were made where necessary. The coverage was then projected to UTM Zone 15, NAD83, unshifted coordinates and broken into 100k tiles based on a mathematically defined 100k tile coverage. A county-tiled version of the layer has also been developed and is in extensive distribution. |
