How about adding control to the projects? Both spheres and checkered targets come out very poor. It should be possible to record the coordinates of one or several baseplates or something similar...
With the BLK2GO you can use scan targets (spheres or plate targets) to connect to a survey control datum. Depending on the size of the target it is recommended to pause a moment during capture near the targets to ensure sufficient point cloud coverage of the target. A minimum of three targets is required to shift the data onto datum.
