| Title | Duluth Area Wetlands Inventory (D.A.W.I) |
| System Name | wetlands.shp |
| Abstract | Wetland area features mapped as part of the Duluth Natural Resources Inventory (NRI). |
| Purpose | Wetlands permitting support, Environmental Review, Watershed Management, Wildlife Management, |
| Time Period of Content Date | September 1997 |
| Currentness Reference | Source aerial photography was from September 1997 for St. Louis County and September 1999 for the small part of Carlton County. The interpretation effort was completed in April, 2001. |
| Progress | Complete |
| Maintenance and Update Frequency | none planned |
| Spatial Extent of Data | Includes the corporate limits of Duluth as well as the watersheds that flow through city (see spatial_extent.gif) |
| Bounding Coordinates UTM zone 15, NAD83 | E = 581,855 W = 549,810 N = 5,197,965 S = 5,166,605 |
| Place Keywords | Minnesota, Duluth |
| Theme Keywords | Wetland, Lake, Bog, Swamp |
| Theme Keyword Thesaurus | None |
| Access Constraints | None |
| Use Constraints | Federal, State, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, State, or local government or to establish the geographical scope of the regulatory programs of government agencies. |

| Associated Data Sets | base maps used for mapping were rectified, infra-red color DNR aerial photographs |
| Section 2 | Data Quality Information - - - - - - top |
| Attribute Accuracy | The data was field checked according to original agreement between City of Duluth and NRRI. Accordingly, 10 percent of the polygons were field verified. Check plots were compared to insure completeness of data and check for label errors. |
| Logical Consistency | Data are topolocially correct using Arcview GIS software. All polygons are closed and lines intersect where intended. |
| Completeness | All photo-interpretable wetlands are mapped. In the treeless areas, 1/8 acre wetlands are mapped. In forested areas, small open water and emergent wetlands are mapped. In general, the minimum mapping unit is from .5 to 2 acres. |
| Horizontal Positional Accuracy | Horizontal positional accuracy for the digital data is tested by visual comparison of the source with hard copy plots. |
| Vertical Positional Accuracy | Not Applicable |
| Lineage | Digital wetlands data were manually digitized on screen into topologically correct data files using Arcview software. Polygon labels were added following National Wetland Inventory (NWI) standards. |
