Indeed, the hologram in the meeting was just the "powerpoint slide", abstract to convey the idea: death star, trench, boom. Noone stood up and went studying it like a map, that was not its purpose at all.
most of the people look as enthused by that hologram as I feel about seeing someone's slide deck. most fighter jocks tend to have the attitude best expressed in Aliens, "I only need to know one thing...where they are".
