Which of the following is NOT one of the professional technical standards for surveying?

Surveying theory is indeed not classified as a professional technical standard for surveying. While theory plays a vital role in understanding the principles that guide surveying practices, the standards focus more on practical applications and methodologies that ensure accurate and reliable survey results.

Precision refers to the degree of exactness and is crucial in surveying as it determines how closely measurements agree with each other. Boundary construction involves the physical aspects of establishing property lines, which is essential in creating accurate land surveys. Stipulating that all boundaries shall be connected to identifiable physical monuments ensures that surveys are tied to fixed points in the landscape, which is fundamental in maintaining the integrity and verifiability of boundary locations. Thus, the other choices reflect concrete practices and guidelines, while surveying theory serves more as a foundational knowledge base rather than a standard.
