Which term includes surveys conducted to establish positions of points of reference for projects with a limited geographic coverage such as a municipality, large isolated tract, or group of municipalities, covering primary control (third order), secondary control (fourth order) and tertiary control?

Which term includes surveys conducted to establish positions of points of reference for projects with a limited geographic coverage such as a municipality, large isolated tract, or group of municipalities, covering primary control (third order), secondary control (fourth order) and tertiary control?

• A. Geodetic Control Surveys
• B. Cadastral Surveys
• C. Project Control Surveys
• D. Public Land Surveys

Answer: (C)

Surveys conducted to establish a reference framework for a specific project within a limited area are called Project Control Surveys. This approach creates a control network tailored to the project’s geographic scope—such as a municipality or a group of municipalities—and uses a hierarchy of accuracy: primary control points (third order), secondary control points (fourth order), and tertiary control for local checks. This ensures every measurement in the project is tied to a consistent coordinate system derived specifically for that area, which is essential for accurate design and construction within a confined region. Geodetic Control Surveys cover broader ranges and aim to establish widely distributed, stable control networks over large areas, not just a single project site. Cadastral Surveys focus on mapping and establishing boundaries of individual land parcels. Public Land Surveys refer to historical or government-wide surveys of public lands, not project-specific networks.
