| 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. | |||
| Progress | Complete | |||
| Maintenance and Update Frequency | As needed | |||

| 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. | |||
