For Other Property Surveys Category III, what is the linear error of closure?

Linear error of closure is the allowable misclosure of a closed traverse expressed as a proportion of the total distance measured. For Other Property Surveys Category III, the standard is one foot of misclosure for every five thousand feet of distance, which equals a relative error of 0.02%. This means that if you traverse 5,000 feet, you may end with up to a 1-foot discrepancy; for 10,000 feet, up to 2 feet, and so on. This level provides a practical balance of precision appropriate for this survey category. The reason this is the best answer is that it matches the designated tolerance for Category III surveys. Other options either loosen or tighten the tolerance or use different units that translate to a different ratio (for example, one foot per 10,000 feet is looser, two feet per 5,000 feet is stricter, and one inch per 500 feet equals about one inch per 6,000 feet, which is not the same 1:5,000 standard).
