The idea is to ensure any reference points near or inside the project area are suitable for use in the control network by first gathering information, then judging their reliability, and finally confirming their current status on the ground. You start by researching each point—checking history, past coordinates, marker condition, and any known disturbances or movements. Next, you evaluate them for appropriateness—whether their accuracy, stability, age, and location meet the project’s requirements and whether datum or alignment issues exist. Finally, you verify them on site—re-measuring or tying them to current observations to confirm their coordinates and document the results for project use. This combination—researching, evaluating, and verifying—best captures the necessary steps to determine if an existing point can reliably support the project control network.
