Coordinate
Warning: for georeferenced control points, you must specify ellipsoidal height, and not the height above sea level, if your spatial reference system does not specifically include an orthometric vertical datum. For the WGS 84 reference system, for example, you must enter ellipsoidal heights; if your system is WGS 84 + NAVD 88 geoid height, then you must use heights above sea level.
For more information, please refer to Useful concepts.
Edit the control point 3D position in the corresponding fields. Coordinate units depend on the chosen coordinate system:
Check point
Enable this option if you want to use the control point for checking only. In such case the control point will not be considered during the aerotriangulation.
