Survey Control Data
Data on points with known precise coordinates established through geodetic surveying. It serves as the reference for all spatial data and is used to ensure the accuracy of the orientation, distance, and relative elevation of 3D models.

Survey control data are known precise coordinate points established through geodetic surveying methods, and are the benchmark for all spatial data; if a 3D model is not bound to a real coordinate system, its orientation, distance and relative elevation may have systematic deviations.
