2025 WA GIS Conference

Are you ready for the new datum? A new National Spatial Reference System (datum will be launched in 2026. Implemented by the National Geodetic Survey, NATRF2022 will supersede NAD83-2011. Per WA RCW, this will become the datum of record when the change happens. With this change will come new state plane projections (north zone, south zone, and a new statewide projection), as well as low distortion projection (in development). In addition, the US Survey foot has bene deprecated, and all new projections will reflect the change to the international foot. This session provides the background, the potential impacts for WA, and examples of how engineering/surveying and GIS firms and organizations are preparing for the changes.
