Description:
Abstract: Geomorphology of Minnesota - Isolated Landform Structures are essentially cartographic arcs representing isolated glacial features that were mapped in conjunction with the 1:100,000 scale Geomorphology of Minnesota layer. The data are intended for cartographic display, rather than database applications.
Purpose: To serve as an essential information source in the development of level 4 Ecological Classification System (ECS) delineations (Land Type Associations).

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: Source table LFRM_STRCTLN2.DBF: 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 Report: Data are topolocially correct using ARC/INFO 7.0.3.
Completeness Report: Statewide coverage is available.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: Source layer landfln2: Unknown. The features tend to be caricatures of the real_world objects being mapped.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: Source layer landfln2: Not Applicable
Lineage:
Source Information:
Source Scale Denominator: Source layer landfln2: 100000
Process Step:
Process Description: Attribute Lineage for source table LFRM_STRCTLN2.DBF: DNR was the principal party responsible for the development and maintenance of a standard database design and valid codes lists. This coverage underwent extensive data scrubbing to locate all attribute coding errors across quad boundaries and also to verify non-valid geomorphic codes and code combinations. Corrections were made where necessary.

Attribute:
Attribute Label: LINE_CODE
Attribute Definition: This item contains values designed to store the original values as digitized in Autocad. As Autocad does not support topology or attributing, codes were assigned to linework to help identify what types of landforms the polygon features represented.
