Legal Exposure FAQ

Is my firm liable if I use public coordinate data (e.g. from a State DOT)?
Generally, professionals are responsible for validating external data before applying it to a specific engineering or survey project. Reliance on public data without "verification of fit" is a common source of negligence claims.
What is the typical 'Standard of Care' for coordinate transformations?
The Standard of Care usually requires following industry-standard geodetic practices, such as using EPSG-published parameters and performing 3rd-party validation (e.g. comparing against known benchmarks).
Can a disclaimer on my map prevent all coordinate liability?
Disclaimers help manage "low-stakes" informational risk, but rarely shield against negligence in professional service contracts where a specific duty of care is owed to a client (e.g., construction staking).

The $50,000 Geodetic Drift Liability: 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 $50,000 Professional Liability 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

Your phone's GPS can be off by 30 meters. 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 permanent 1-meter offset.
