One new feature will be a state-wide zone for projects that extend over more than one zone. [2] The NGS expects to release the new spatial reference system and new zones in 2025. [3] As with earlier systems, the name of the new system, State Plane Coordinate System of 2022, indicates a year earlier than the actual year of release.
