⚠️ Datum Hazard: Read Before Conversion

Coordinate values only have meaning when attached to a Datum.

  • WGS84: Standard for GPS, Google Maps, Web Mercator.
  • NAD27: Used in older USGS topographic maps (pre-1983).

Using the wrong datum can shift your position by 20-100+ meters. Always verify the source datum of your coordinates.

FAQ

Q: Are these real cases?

A: Yes, these scenarios are based on documented technical failures in SAR, aviation, and civil engineering.

Q: How can I prevent these?

A: Each case study links to a specific Validation Checklist designed to catch that exact error before deployment.

Q: Can I simulate these errors?

A: Yes, use our Coordinate Mistake Simulator to see the magnitude of these errors in real-time.

Professional Risk Notice

Using the wrong datum or applying coordinates without grid-to-ground correction can cause 1–400 metre positional errors — a leading cause of surveying negligence claims and contract disputes.
