News: NATRF2022

The United States, as part of its reference frame modernization, plans to replace its North American Datum of 1983 (NAD83) with a new North American Terrestrial Reference Frame (NATRF2022), creating 1.3 to 1.5 m horizontal coordinate differences at the Canada-U.S. border with respect to Canada’s NAD83(CSRS). NATRF2022 was originally planned to be rolled out in 2022, however the U.S. National Geodetic Survey has recently announced a delay until approximately 2024 or 2025.

To begin informing the Canadian geospatial community of the U.S.’ move to NATRF2022, a freely available technical note has been published in GEOMATICA, and a quick reference pamphlet has been prepared.

This site provides end-users with the geodetic data, tools and information they need for a range of commercial and private uses. One of the most popular services is the online CSRS-PPP service, which provides centimetre-accuracy positioning in either NAD83(CSRS) or ITRF using GNSS technologies.
