National Wetlands Inventory – Wetlands Mapper

National Wetlands Inventory - Wetlands Mapperby Mitch Bergeson, National Standards and Support Team, US Fish and Wildlife Service Division of Habitat and Resource Conservation

The Wetlands Mapper is an internet discovery mechanism designed to promote greater awareness of wetlands geospatial data applications and to deliver easy‐to‐use, map like views of America’s wetland resources in a digital format. The Wetlands Mapper integrates the U.S. Fish and Wildlife Service’s National Wetlands Inventory data with other resource information to produce timely and relevant management and decision support tools for all of the United States, Puerto Rico, U.S. Virgin Islands, Guam and Saipan.

The Wetlands Mapper is a rich internet application built with the ArcGIS API for Flex.   The application has a user-friendly interface that provides an interactive environment for users to view and query wetlands data displayed on Esri imagery, Esri street maps and Esri and USGS topographic maps.  When a wetland is selected, a pop-up window provides specific information about the classification, type and size of each feature, and the date and type of source data used for mapping.  The information pop-up window also includes links to further describe the wetland classification (decoder) and project specific metadata that describes mapping procedures.  Historic map information including descriptions of climate, geographic setting, soils and wetland communities is also provided.

The application provides navigation tools to search by place name or address and zoom to geographic regions.  There are tools for measuring distance and area, downloading data and printing custom maps and the application can be viewed at full screen to utilize your entire monitor.

Other available layers include Riparian habitats of the western United States, mapping status layers for both wetlands and riparian data that show where mapping has been conducted, data source information and wetland areas that may be of special interest.

The Wetlands Mapper is designed to provide reliable ecological information and direct users to other potential sources of information. It is not intended to provide legal or regulatory determinations or products. Unintended use of the information or products is discouraged.  Persons 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 specific agency regulatory programs and proprietary jurisdictions that may affect such activities.
