Control surveys are classified into what two main types?

Control surveys are categorized by the reference framework and geographic scope into geodetic control and project control. Geodetic control surveys establish a wide-area network tied to a geodetic datum, accounting for the Earth's curvature and providing precise coordinates across large regions. Project control surveys create a local framework for a specific project, usually using a plane coordinate system, with tie-ins to the geodetic network to ensure construction aligns with the plan, but not intended to serve as a long-range reference for the entire region. The other options describe boundaries and cadastral work, general survey types, or the project’s purpose, rather than how the control network is classified.
