Section 1 Overview
Originator University of Minnesota-Duluth Geology Department; MN Geological Survey, MN DNR
Title Geomorphology of Minnesota
Abstract 1:100,000 scale geomorphology data describing a wide variety of conditions related to surficial geology within a hierarchical classification scheme that was devised for use within Minnesota.
Purpose To serve as an essential information source in the development of level 4 Ecological Classification System (ECS) delineations (Land Type Associations).
Time Period of Content Date 1997
Currentness Reference Data were derived from a wide variety of image and hardcopy data sources of varying vintages.

Section 2 Data Quality
Attribute Accuracy Source table LFRM_GEOPY2.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 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 Source layer landfne2: Unknown
Vertical Positional Accuracy Source layer landfne2: Not Applicable
Lineage Attribute Lineage for source table LFRM_GEOPY2.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.
