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.

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 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.
