Wetland Web Mapping Services

NWI geospatial wetlands data and reference layers can be accessed by web-based applications and mapping software using the following Open GIS Consortium (OGC) compliant web mapping services. These services allow GIS users to display and query wetlands data without the overhead of data management. Additionally, web developers can consume these services to include NWI wetland data into their own mapping applications. These services are updated biannually along with the Wetlands Mapper.

Representational State Transfer (REST)

Software developers can incorporate our REST services within their map applications using the link provided.
GIS users can connect to these services using mapping software such as ESRI's ArcGIS by following the directions provided.


REST Service address: https://www.fws.gov/wetlands/arcgis/rest/services



Web Map Services (WMS)

Software developers can incorporate our WMS services within their applications using the service information and links provided. GIS users can connect to these services using mapping software such as ESRI's ArcGIS by following the directions provided.


WMS Service Name: Wetlands

Projection: GCS, NAD83

OGC Version: 1.3


Wetlands Data*: https://www.fws.gov/wetlands/arcgis/services/Wetlands/MapServer/WMSServer?request=GetCapabilities&service=WMS

Wetlands Raster*: https://www.fws.gov/wetlands/arcgis/services/Wetlands_Raster/ImageServer/WMSServer?request=GetCapabilities&service=WMS

Wetlands Status: https://www.fws.gov/wetlands/arcgis/services/Wetlands_Status/MapServer/WMSServer?request=GetCapabilities&service=WMS

Riparian Data: https://www.fws.gov/wetlands/arcgis/services/Riparian/MapServer/WMSServer?request=GetCapabilities&service=WMS




* Note:  Due to the quantity and complexity of the wetlands data, the Wetlands Data layer only displays at 1:250,000 scale and greater. Therefore, we recommend you use the Wetlands Raster WMS Service, which identifies generalized wetlands data at all map scales in conjunction with the Wetlands WMS or REST Service.
