The point is to ensure a constant ground sample distance in the photos.
So reference should be ground for the best outcome, UNLESS it's not much change in elevation then(~10ft)?
It really just depends on your use case, what you are trying to accomplish, and what processing software you are using. You may want to ask the processing software vendor which approach will yield the best results for your goals using their system.
