Alaska Hydrography Technical Working Group
The Alaska Hydrography Technical Working Group, or AHTWG, is an active committee focused on the coordination of current and future surface water mapping in Alaska. AHTWG is charted under the Alaska Climate Change Executive Roundtable (ACCER) and works closely with the Alaska Geospatial Council. AHWTG is comprised of six federal agencies four State of Alaska entities, as well as numerous technical advisors from various groups.
The AHTWG promotes a strategic vision that supports the maintenance, stewardship, and use of common hydrography datasets for state, federal and other partners. Specifically, the AHWTG:
- Promotes the implementation of a Statewide Stewardship Model
- Coordinates statewide hydrography editing standard operating procedures, standards and editing workflows
- Facilitates development of feature level meta data standards
- Provides input to improving the NHD data model and tools
- Communicates hydrography issues to leadership and technical staff
For the benefit of all digital hydrography editors and users in Alaska.
The group is co-chaired by a representative from the USGS and the Alaska Hydrography Database at the University of Alaska. AHTWG has adopted AK Hydro as the preferred stewardship model to support surface water mapping updates in Alaska and to move updated hydrography from partners into the NHD.
