Michigan Dept. of Environment, Great Lakes, and EnergyThis map series is maintained by the Michigan Department of Natural Resources', Michigan Resource Inventory Program (MRIP) . Each land cover category is depicted by a polygon and identified with a land cover code. Patterned land cover maps have also been created for selected counties depicting urban, agriculture, woodland, and wetland categories (products 201, 202, 203, and 204 respectively). This layer includes only the land cover codes that represent the different vegetative and open water categories of wetlands captured in the MIRIS Land Cover effort. This layer was produced from the source MIRIS 1978 LULC Dataset. All wetland land cover codes were queried and exported in a GIS environment for use in the Part 303 State Wetland Inventory completed in 2007. This dataset is not updated Its was used to construct the Wetland Inventory Maps https://www.michigan.gov/egle/about/organization/water-resources/wetlands/inventory-maps Field Name Descriptions MIRISCode Combined level codes used to determine the land cover type.
