Short description:
Wetlands of Indiana from the National Wetland Inventory (NWI, 2014) - Shows the extent, approximate location, and type of wetlands and deepwater habitats in Indiana, as provided by the National Wetland Inventory (NWI) of the U.S. Fish and Wildlife Service (USFWS). These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps.

This map service includes the Wetlands Project Metadata layer, which contains project-specific wetlands mapping procedures and information on dates, map scales, and emulsion of imagery used to map the wetlands within specific project boundaries.

Digital wetlands data are intended for use with base maps and digital aerial photography at a scale of 1:12,000 or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed nor intended to represent legal or regulatory products.
