Changes Afoot After 2022: State Plane and the Death of the U.S. Survey Foot

Change is nearly upon us. Design of the State Plane Coordinate System of 2022 (SPCS2022) is almost done, and on December 31, 2022, the U.S. survey foot will be “deprecated.” This means that it will be deemed obsolete and should be used for historical and legacy applications only. It will be superseded by the international foot definition (i.e., 1 foot = 0.3048 meter exactly) for all applications, including SPCS2022. However, SPCS2022 will not be released until 2025, along with the rest of the modernized National Spatial Reference System. This webinar gives an overview on the status of SPCS2022 and on making an orderly transition to the international foot with minimum disruption.

Note: Due to an unusually large number of questions sent in during and after this webinar, NGS created this Question and Answer document [PDF] for download.
