The maximum allowable Relative Positional Precision for an ALTA/NSPS Land Title Survey is specifically set to ensure accuracy in land surveys, which is crucial for title insurance and real estate transactions. The standard established for this precision is 2 cm plus 50 parts per million.

This means that for every 1,000,000 units of distance measured, an additional precision allowance of 50 centimeters is permitted. This calculation allows surveyors to determine how closely the positional data aligns with the actual boundaries and features of the land. The 2 cm base reflects a balance between the need for precision in legal matters and the practical constraints of surveying in the field.

Choosing this standard maintains integrity and trust in land surveys, ensuring that property boundaries are accurately represented and disputes are minimized. Understanding this concept is vital for anyone involved in real estate, surveying, or title insurance, as it impacts the validity of land claims and ownership rights.
