APLS is actively engaged in the effort to prepare for the new national datums planned for release in 2022. Below is information to keep you updated on progress.
State Plane Coordinate System - Low Distortion Design
APLS is happy to report that we have met our fundraising goal for the Low Distrortion Design software! Part of this preparation for the 2022 Datum is a redesign of State Plane Coordinate System (SPCS) zones. APLS raised funds to purchase an annual lease of Low Distortion Projection (LDP) Design Software. The software will allow APLS members Brian Fisher, and Jack Avis to design SPCS zones that are optimized for Arizona communities. Brian and Jack are also the co-chairs of the Arizona Geographic Information Council (AGIC) SPCS 2022 Work Group organized to lead this effort.
