Section 1	Identification Information - - - - - - top
Originator	Natural Resources Research Institute
Title	Beaver River Watershed Wetlands
System Name	beaver_wetlands.shp
Abstract	Wetland area features mapped as part of the North Shore Wetlands Mapping Project funded by the Minnesota DNR Coastal Program.
Purpose	Wetlands permitting support, Environmental Review, Watershed Management, Wildlife Management,
Time Period of Content Date	September 1998
Currentness Reference	Source aerial photography was from September, 1998.   The interpretation effort was completed in Winter 2004, and Spring 2005.
Progress	Complete
Maintenance and Update Frequency	none planned
Spatial Extent of Data	Includes the watershed of the Poplar River (see beaver_area.jpg)
Bounding Coordinates UTM zone 15, NAD83	E = 629,569.924652 W = 609259.056186 N = 525,2214.293292 S = 5,234,019.508923
Place Keywords	Minnesota, Beaver River, Lake County
Theme Keywords	Wetland, Lake, Bog, Swamp, Cowardin
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.

Browse Graphic File Description	This file shows extent of wetland mapping completed for the Beaver River Watershed.
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 the DNR Coastal Program and NRRI.  Accordingly, 10 percent of the polygons were field verified.  Check plots were compared to insure completeness of data and checked for label errors. (field check notes) (field check photos) (field check photo index image)
Logical Consistency	Data are topologically 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.
