The final stages of building the Modernized National Spatial Reference System (NSRS) have now come into focus. NGS is now in the process of compiling, organizing, and cleaning all of the relevant GNSS and leveling data contained within the NGS Integrated Database and the OPUS shared solutions database. For the past several years, NGS’ GPS on Bench Marks program has been encouraging stakeholders and partners around the country to submit GNSS data to NGS on marks that they use, to ensure that they have updated RECs when the new system comes out, and to improve the local accuracy of the NAVD88-to-NAPGD 2022 transformation tool. While NGS will continue to accept submissions of user data into the future, on February 29, 2024 we will be closing the doors for GNSS and leveling data to be considered for the initial REC national adjustments and for use in building the transformation tools.
