Rejiggering the launch site for an unmanned craft, with several seconds round trip phase lag for course corrections from the ground control, is an even worse problem.
Chiang'e 3 had a ~30 second "hovering" stage during its decent, during which it scanned the area it was over (using radar and laser IIRC), and itself made the decision where exactly to land based on that information.
AFAIK ground control could have interrupted and overridden the process at any stage, but did not.
