Which orders are handled by LMV and LMS respectively in the geodetic control point framework?

• A. Third and Fourth Orders
• B. First and Second Orders
• C. Fourth and Third Orders
• D. Second and Third Orders

Answer: (A)

In geodetic control, each order defines how precise the control points need to be and what they’ll be used for. The LMV network is set up to achieve the accuracy level required for Third Order control, which is suitable for substantial mapping and engineering work that needs solid precision but not the very highest level. The LMS network is designed for Fourth Order accuracy, which is appropriate for basic mapping tasks and cadastral work with looser tolerances. Since Third Order requires more precision than Fourth, LMV corresponds to Third Order while LMS corresponds to Fourth. Higher-order (First and Second) control demands are handled by other, more stringent networks beyond these two.
