Note: Working Group and Subcommittee Charter Updates

The Advisory Committee on Water Information (ACWI) and FGDC created the Subcommittee on Spatial Water Data (SSWD) to assist coordination of Federal and non-Federal interests in spatial water data, including (1) facilitating the exchange of information and transfer of data; (2) establishing and implementing standards for quality, content, and transferability; and (3) coordinating the identification of requirements and the collection of spatial data to minimize duplication of effort where practicable and economical.

The subcommittee is exploring three initial use cases, which help to identify critical data needs, then facilitating and making the needed datasets openly available as Web services and downloads. The initial use cases were chosen to cover important societal needs and to address several diverse facets of the water information infrastructure. Learn more about the Open Water Data Initiative
