The Interagency Working Group on Ocean and Coastal Mapping (IWG-OCM) is a working group of the Subcommittee on Ocean Science and Technology (SOST). SOST serves as the Ocean Science and Technology Interagency Policy Committee under the National Ocean Council. The IWG-OCM was established in 2006 to "facilitate the coordination of ocean and coastal mapping activities and avoid duplicating mapping activities across the Federal sector as well as with State, industry, academic and non-governmental mapping interests." (National Ocean and Coastal Mapping Strategic Action Plan 2009).
