Abstract:
This Michigan Department of Environmental Quality (MDEQ) Wetland Inventory Map is a tool to assist in identifying wetlands and provides only potential and approximate location of wetlands and wetland conditions.
Purpose:
This Michigan Department of Environmental Quality (MDEQ) Wetland Inventory data is intended to be used as one tool to assist in identifying wetlands and provides only potential and approximate location of wetlands and wetland conditions.
Supplemental_Information:
The MDEQ produced this map from the following data obtained from other agencies or organizations:

1.  The National Wetland Inventory (NWI) conducted by the United States 
Fish and Wildlife Service through interpretation of aerial photos and topographic data.   
2.  Land Cover as mapped by the Michigan Resource Inventory System (MIRIS),
Michigan Department of Natural Resources, through interpretation of aerial photographs. 
3.  Soils as mapped by the United States Department of Agriculture, Natural Resource
Conservation Service (NRCS).

This map is not intended to be used to determine the specific locations and jurisdictional
boundaries of wetland areas subject to regulation under Part 303, Wetlands Protection,
of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended.
Only an on-site evaluation performed by the MDEQ in accordance with Part 303 shall be 
used for jurisdictional determinations.  A permit is required from the MDEQ to conduct
certain activities in wetlands regulated under Part 303.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
NWI:  No stated horizontal accuracy.  NWI:  This data set represents the extent of wetlands and deepwater habitats that can be determined with the use of remotely sensed data and within the timeframe for which the maps were produced. Wetlands are shown in all of the conterminous 48 states and the District of Columbia. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data, and the amount of ground truth verification work conducted. 
There is a margin of error inherent in the use of imagery, thus detailed on-the-ground inspection of any particular site, may result in revision of the wetland boundaries or classification, established through image analysis. 
Wetlands or other mapped features may have changed since the date or the imagery and/or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. 

MIRIS 1978 Land Cover/Land Use:  Accuracy value = +/- 80 feet

Hydric Soils:  No stated horizontal accuracy.  This dataset is not designed for use as a primary regulatory tool in permitting or citing decisions, but may be used as a reference source.  This is public information and may be interpreted by organizations, agencies, units of government, or others based on needs; however, they are responsible for the appropriate application.  
Federal, State, or local regulatory bodies are not to reassign to the Natural Resource Conservation Service any authority for the decisions that they make.  The NRCS will not perform any evaluations of these maps for purposes related solely to State or local regulatory programs.
Photographic or digital enlargement of these maps to scales greater than at which they were originally mapped can cause misinterpretation of the data.  If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale.  The depicted soil boundaries, interpretations, and analysis derived from them do not eliminate the need for onsite sampling, testing and detailed study or specific sites for intensive uses.  Thus, these data and their interpretations are intended for planning purposes only.

Process_Description:
The three datasets referenced above were combined using a 'UNION' geoprocessing routine in ArcGIS software, by the MI Center for Shared Solutions and Technology Partnerships (CSS & TP).  The 'SYM' attribute field was created to represent layer coverage and overlap for every polygon in the dataset, so wetland spatial data could be tracked back to its original source layer.
