Once a surveyor has "set" some distances and directions to re-establish boundaries, the resulting measurements must be documented and compared to official records. Regulations require that all results, conflicting or otherwise must be recorded in the performance of the survey. Surveyors commonly "set" 2 or more distances between two (2) adjoining properties to re-establish the property line, and "measure" the remaining distances, in an effort to get a solid mathematical match of all the evidence.
