Wisconsin Department of Natural Resources - Wisconsin Wetland Inventory Geodatabase

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 TechnologyLiDAR
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.
