Control point surveying

Control point surveying is a geodetic method used to determine precise reference points in the terrain. These control points serve as benchmarks for future measurements and mapping, ensuring accuracy and consistency.

Control point surveys often utilise GNSS equipment, total stations, or other high-precision instruments. Control points are typically permanent structures such as concrete pillars or metal markers placed in the landscape and georeferenced with high accuracy. They are essential in construction, mapping, and land surveying where exact spatial data is critical.
