Use control points for adjustment - This is used with accurate survey control, when used it weights the positions of the photos where the control is marked positioning them exactly at this control location. Use control points for rigid registration - This is used when the control is not survey accurate, i.e. if control coordinates are extracted from lower resolution scene to position (spatially reference) imagery captured from the ground. When used the photos exterior orientation is first computed then the block is positioned over the control using a network least square adjustment distributing the error across all the controls
