True but I'd believe the ship is better at surveying and sensing stuff even from outside of atmo than a shuttle would be. To me one would have the capability of building a detailed map while the other would only have the capabilities needed to avoid running into something.
Maybe the shuttles could do a rough survey but in those cases I'd almost expect the ship to just drop/launch a handful of sensing satellites. The rest of the time I imagine a lot of focusing on one region or planet by different specialist teams rather than spreading the teams out over the whole system. That way they've got pretty quick access to the ship's computing resources as well.
Not saying that a widespread effort wouldn't happen just that spreading the team to five drastically different locations seems unwise somehow or unnecessary a lot of the time.
Trek works strictly on the "we send shuttles with people over satellites" every time policy. They also don't have multiple teams because only one team is out. tbh, I voted for 2 over 4 is over manpower concerns, or I'd rather it have 4 shuttles for the ability to use multiple teams at once.
(The ship is *as* good as shuttles, generally, at scientific studies, don't ask me how, it's not realistic.)
