Welcome to the Alpha Zone: A Preview of State Plane 2022

July 20, 2023  |  2:00-3:30 pm, ET

Presenter: Dr. Michael Dennis, PE, PLS, Geodesist, Observations and Analysis Division (OAD), NGS; Krishna Tadepalli, Chief of the Geodetic Applications Branch, NGS

Modernization of the National Spatial Reference System (NSRS) is becoming a reality. Scheduled for completion in 2025, NOAA’s National Geodetic Survey (NGS) is releasing preliminary (“alpha”) versions of NSRS modernization products and services through a dedicated NGS alpha website. First among these is the State Plane Coordinate System of 2022 (SPCS2022). This webinar provides a preview of SPCS2022 through its various alpha products, including:

• Preliminary SPCS2022 zone definitions, coordinates, and performance statistics
• NGS Coordinate Conversion and Transformation (NCAT) tool support for SPCS2022
• Downloadable distortion maps and datasets used to create them
• Interactive web maps of SPCS2022 zone and distortion

The alpha release allows software developers, state stakeholders, and other NGS partners and customers to see SPCS2022 as it evolves toward completion. It also provides an opportunity to give feedback during the final stages of development, to ensure that SPCS2022 is an optimally designed part of the modernized NSRS.
