California Civil Engineering Surveying Practice Exam

The level of accuracy is the measure of uncertainty for the entire survey, expressing the bound within which the survey results are considered acceptable. It is the term that communicates the overall precision plan for the project, effectively serving as the tolerance for the network as a whole. This fits because it explicitly names the expected uncertainty or error envelope across all measurements, not just a single value or property.

The other terms don’t convey that bound in the same way. Level by itself is too vague; accuracy describes closeness to true values but doesn’t specify the allowable bound; and tolerance refers to a numeric limit, whereas the level of accuracy is the described measure that defines that limit for the entire survey.
