The Cumulative Boundary & Engineering Rework Exposure: NAD83 vs WGS84

Because the North American Plate moves ~2cm/year, NAD83(2011) and WGS84(G1762) currently diverge by over 2.2 meters. Using a "standard" GPS WGS84 coordinate for a high-precision NAD83 cadastral staking has triggered Boundary Dispute Geodetic Offset claims for foundational rework and utility misplacement.

Warning: Verify Your Calculation

Coordinate accuracy varies by device and datum. Do not use these results for legal or construction purposes without checking:

GPS Accuracy Alert

Consumer GNSS devices typically achieve 3–10m accuracy, though urban multipath can introduce errors up to 20–30m. This can cause critical errors in your data.

Check My Accuracy

Datum Shift Risk

Using the wrong coordinate system (e.g. WGS84 vs NAD83) creates a systematic ~1 to 2m tectonic reference frame offset.
