Require Standard Review →Understanding the Safety Factor
In geodetic engineering, a safety factor (Tolerance / Equipment Accuracy) of less than 3.0 is generally considered unacceptable for professional sign-off. This is because GPS/GNSS receiver accuracy is typically stated at the 1-sigma (68%) confidence level.
To guarantee that 99.7% of all measurements stay within your contract tolerance (3-sigma confidence), your equipment must be natively capable of resolving to a dimension three times tighter than your absolute project limit. Furthermore, unmitigated Datum Shifts (such as confusing WGS84 for a local grid) bypass equipment accuracy entirely, injecting a static 1-2 meter bias that guarantees structural failure.

Civil Litigation Benchmarks for Surveying Negligence
Professional Liability data indicates that early settlement for boundary disputes typically ranges from $5,000–$20,000. Full-scale trial defense for geodetic negligence claims averages $60,000–$150,000+ in legal fees alone, often exceeding the value of the disputed land.

GPS Accuracy Alert
Your phone's GPS can be off by 30 meters. This can cause critical errors in your data.
