Wisconsin Wetland Inventory Geodatabase, WI DNR Mixed Public content

Description:
The principal focus of the wetland inventory is to produce wetland maps that are graphic representations of the type, size and location of wetlands in Wisconsin. Currently, there are two different datasets that have been created using different mapping methods and technologies. The majority of the state was mapped using traditional stereo-pair, black-and-white, infrared photography. Within this context, the objective was to provide reconnaissance level information on the location, type, size of these habitats such that they are accurate at the nominal scale of the 1:20,000 (1 inch = 1667 feet) base map. LiDAR Technology LiDAR has advanced the ability to see and map wetland and surface water features. New wetland mapping is underway in areas across the state at a nominal scale of 1:2000 (1 inch = 166.7 feet). The data are being mapped according to the National Wetland Inventory standards using new methods. Please see the WWI SOP for more information. See LiDAR based status map for more information. Data The download contains both the older, high altitude, stereo-photo based mapping as well as the newer LiDAR based mapping.  Any older WWI data within a new project area boundary have been removed. The DNR recognizes the limitations of using remotely sensed information as the primary data source. They are to be used as a guide for planning purposes. There is no attempt, in either the design or products of this inventory, to define the limits of jurisdiction of any federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Anyone intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory programs and jurisdictions that may affect such activities. The most accurate method of determining the legal extent of a wetland for federal or state regulations is a field delineation of the wetland boundary by a professional trained in wetland delineation techniques.
