  • As an alternative, a Keyhole Markup Language (KML) file has been created to view Wetlands Data with
    Google Earth.

  3. Enter the following WMS address in the URL text box: 

    Wetlands Data WMS address: 
    Wetlands Status WMS address: 
    Riparian Data WMS address:   
  4. Click on the “Get Layers” button to view the service and layer information.
  5. Click on the “OK” button to add the connection and view it in ArcCatalog. You will see the connection show up under “GIS Servers”
  6. This WMS connection will now also be available in ArcMap under “GIS Servers” after you select “add data”.

Note: it is best if you load a base reference layer to help you get oriented with the Wetlands data. Due to the quantity and complexity of the wetlands data the WMS service only displays at 1:250,000 scale and greater.
