Wetlands Mapper

Our new Wetlands Mapper is now available. * This mapper hosts the most current digital data and metadata available.
*
The new Wetlands Mapper may experience technical difficulties as we add new features. If the database does not load within a reasonable amount of time, please try back later.

Characteristics of our new Wetlands Mapper
  • Data are from the Wetlands Master Geodatabase. This provides a truly seamless digital wetland data layer and map data in a single standard projection.
  • The new wetlands map site is Section 508 compliant.
  • Project goals, data limitations and uses are provided for the users.
  • Enhanced analytical tools are provided.
  • The new Mapper is OGC (Open GIS Consortium) compliant.
  • ArcIMS site administrators can connect to the new Wetlands Mapper servers and include wetlands into their own ArcIMS viewers as background layers.

Customers may also find NWI wetlands data through the The National Map on the hydrography data layer (select Wetlands). The National Map contains other data layers that may be of interest and serves as a companion/backup source of our wetlands data.
