Which system establishes reference points for accurate surveys?

• A. Baseline System
• B. Platting System
• C. Survey Control System
• D. Geodetic Survey System

Answer: (D)

Geodetic systems establish a fixed reference frame and network of control points that anchor all survey measurements to a standard coordinate system. By tying locations to a geodetic datum and accounting for the earth’s shape (ellipsoid) and curvature, they provide precise, consistent reference points across large areas. This framework lets every survey be oriented and compared reliably, which is essential for accuracy.

Baseline, platting, and a general survey control approach each describe pieces of surveying work, but they don’t by themselves supply the comprehensive, earth-fixed reference framework that geodetic surveying does. Baselines are single measured lines, platting deals with map subdivision, and a generic control system covers points used for positioning, but the geodetic system specifically creates and maintains the reference points and datums that underpin accurate surveys.
