    The United States Is Replacing Every Official Latitude, Longitude And Height It Publishes, Existing Coordinates Will Move By As Much As Four Metres, And The Million Survey Marks In The Ground Will No Longer Be What The System Is Measured From

    “The National Geodetic Survey has spent years building a replacement for the reference system that fixes every published position in the country. New geodetic-control submissions into the old system stop being accepted after January 13, 2027…
    Every official latitude, longitude and height published in the United States is going to change, by as much as four metres. The ground being described will not have moved at all. What is being replaced is the reference system those numbers are counted from.
    The National Geodetic Survey is retiring the North American Datum of 1983 [NAD83] and the North American Vertical Datum of 1988 [NGVD88.] Those are the horizontal and vertical reference systems that currently underpin surveying, flood mapping, construction and aviation across the country. In their place will come four new terrestrial reference frames and one new geopotential datum. The agency has kept the national reference system since its predecessor, the Survey of the Coast, was founded in 1807.
    || The reference surface is what is changing ||
    ... A coordinate is not a property of a place; it is a measurement of that place against an agreed reference surface. The United States is changing the reference surface. The four metres is the gap between two descriptions of the same unmoved point.
    That figure is not uniform either, and the agency does not present it as a single national number. Its guidance says the magnitude of change depends on which datum a user currently works in, where in the country they are, and which epoch the new coordinates refer to. Four metres is the outer edge of the range. NGS publishes separate maps for ellipsoid height change, orthometric height change, and horizontal change on the North American and Pacific plates…”
