Introduction
The Mission/Purpose of the Wetlands Subcommittee is:
1) to promote standards of accuracy and consistency in spatial wetlands data financed in whole or in part by Federal funds;
2) to exchange information on technological improvements for collecting spatial wetlands data;
3) to encourage the Federal and non-Federal communities to identify and adopt standards and specifications for spatial wetlands data; and
4) to collect and process the requirements of Federal and non-Federal organizations for spatial wetlands data.

Wetland Mapping Targeting Tool (WMTT)
Introduction • Want to identify areas with greatest need for updated NWI
data to guide the investment of limited resources
• Dataset age alone should not determine update priority
• Data are still contemporary if land cover has not changed
The WMTT was developed to guide investment of resources to best meet needs of a wide array of users.
• Easy to use
• Spatially explicit
• Can be tailored to meet multiple application needs
• Facilitates the budgeting and justification process
• Helps ensure that the NWI dataset is contemporary

Wetland Mapping Targeting Tool (WMTT)
Two primary inputs: • Raster foundation
• Vector overlays
Raster foundation based on four inputs • Land cover change
• Population growth
• Wetland density
• Averaged within HUC12
• Base image properties • Spatial scale
• Emulsion
• Year

Next Steps • Share WMTT with partners
• ArcGIS online
• REST services
Gather feedback
Make additions / modifications where necessary

Interagency Wetland Mapping Workgroup
Introduction • Formed in 2016 with members from NOAA, USGS, and
USFWS – including managers of research and operational datasets that directly support wetland mapping
• IWMW supports the Wetlands Subcommittee through the open exchange of data and techniques across federal agencies to best support the development of the Wetlands layer of the NSDI.

Next Steps
In the coming year, the Wetlands Subcommittee hopes to:
• Develop a maintenance communications plan.
• Further vet the Wetland Mapping Targeting Tool.
• Establish a data development subgroup.
• Continue communications with other federal agencies regarding data and techniques that could be used to support development of the wetlands layer of the NSDI.
• Support production of outreach publications.
• Review Wetlands Subcommittee charter
