Geoff Zeiss posts<\/a> about the forthcoming NATRF2022<\/a> datum, which will replace NAD 83 and NAVD 88 in 2022. It will address the shortcomings of the earlier datums and for the first time provide a common datum for Canada, the U.S. and Mexico. “Practically,” Geoff writes, “this means that elevations may change by up to a meter and horizontal location by up to 1.5 meters. The actual corrections to elevations and horizontal locations will depend on where you are in North America. The greatest changes are in the Pacific Northwest and the least in the southeastern U.S.” [Dave Smith<\/a>]<\/p>\n","protected":false},"excerpt":{"rendered":"
