Relative accuracy—Principles.
The following principles of relative accuracy are provided to guide those who may be analyzing their work by these procedures.
(1) Relative accuracy means the theoretical uncertainty in the location of any point or corner relative to other points or corners set, found, reestablished, or established. A standard of relative accuracy can be achieved by using appropriate equipment and implementing field and office procedures that will result in a 95 percent probability of achieving the accuracy required.
(2) In the application of a relative accuracy standard, the surveyor must consider the established land use patterns, land values of and in the vicinity of the surveyed parcel, and the client's intended use of the property. Higher levels of measurement precision are expected to be used in situations necessitating higher accuracy being achieved.
(3) Each land boundary survey analyzed using relative accuracy should contain a statement reporting the relative accuracy achieved and identifying the method of mathematical analysis used in achieving a stated relative accuracy.
