Survey control

Survey control refers to a set of accurately measured reference points used in mapping and construction. These points serve as fixed benchmarks that ensure all measurements and layouts are consistent and precise across a site. By establishing control points with known positions, surveyors can accurately locate and align features, infrastructure, and boundaries. This foundation is essential for large-scale projects, ensuring that everything fits together correctly and adheres to design specifications. Think of survey control as the accurate “grid” or “anchor points” that guide the entire surveying and construction process.
