NSRS 2022 Esri Software Implementation
Explore the dynamic datum implementation in Esri software for NSRS 2022 preparation, including challenges, benefits, and educational resources. Learn about potential reductions of WGS 84 CRS usage and seamless transitions for legacy NAD83 GIS data to NSRS 2022. Get insights from authoritative sources and discover the client education on transformations through workshops and presentations.

NSRS 2022 Preparation Esri Kevin M. Kelly Melita Kennedy
Dynamic datum implementation in Esri software? 14-parameter 14-parameter time-dependent transformations implemented GGXF Read capability of GGXF files Point motion operations Point motion operations not yet implemented NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 2
Authoritative information sources Information Sources EPSG ISO Geodetic Register NGS website NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 3
Client education on transformations Blogs and UC Technical workshops: Prepare your data for the National Spatial Reference System modernization of 2022 in the U.S. Esri 2025 User Conference Workshops: National Spatial Reference System Updates NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 4
Challenges Software redesign Re-architect massive software stack for time-variable coordinates - Product team support for dynamic datum functionality Internal support Educate colleagues and customers Education Help customers with data that is defined as original NAD83 NAD83 to NSRS 2022 support Data often referenced to different realizations like NAD83 HARN, etc. Sometimes data are referenced to multiple NAD83 realizations! NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 5
Major benefits of NSRS 2022 Potential reduction of WGS 84 CRS usage in favor of NSRS 2022 CRS - Because a time-dependent transformation will exist - WGS84-to-NSRS 2022 Support for NSRS 2022 in Esri software NSRS 2022 and GIS Potential seamless transition of legacy NAD83 GIS data to NSRS 2022 Legacy NAD83 NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 6
Questions for NGS/CGS? Will NGS use GitHub for dissemination of software, data and/or other NSRS 2022 products? -One-stop shop for products -Users can submit issues which are visible to others Please provide test data for any released products -For all transformation grids and models, multiple test points (not at grid nodes) CGS -Any ProjCRS information? Province-wide definitions? Same sets on NSRS 2022? -New transformations NGS & CGS Binational Geospatial Software Developers Summit, 23-24 April 2025, Esri Presentation 7
