I’m afraid this might turn into a grindy score, which isn’t very welcoming to players who join later.
In addition I think more unique places / things / events / whatever are more interesting.

I mean, we can do that, too, and this doesn’t have to determine who wins, I was thinking more of doing something with the aggregate instead.  I just thought it would be neat to keep track.

That was the first I thought of too. Although it could be prevented by having a limited quota of a resource/s for actions for the entire dynasty (which is something I loved from Poke’s, it’s superb).

Tentative red cross because of the fear of grind but I don’t see why I shouldn’t green tick this if the context improves.

Good points, I like it. Maybe giving everyone a fairly large amount of starting supplies would be a good idea instead of trickling them out some way or another.

Although I believe the 69.4 miles between latitudes, not area. Since the distance between longitudinal lines decreases the closer they get to the pole, that area doesn’t stay constant either.

Google also tells me that Antarctica has a total area of 3.5 billion acres.

Well, it’ll be an approximation.  It’s not like if you, say, go from 77 degrees to 78 degrees you’re going to cover all the squarish area between those two latitude lines and whatever the nearest longitude lines are.  We can say that you go in a straight line and can probably see/investigate one mile east and west, so the area you cover is 69.4 miles long x 1 mile wide = 69.4 square miles.  Simple, and we don’t have to do much potentially miscalculated math.

You might be right, though, maybe we should use a less exacting unit.  Just square miles might be good enough?

but let’s take 70 square miles per latitude line.

I could write a simple Wolfram Language script to calculate if people would prefer precision.

I would prefer non-precision.

Quoruming, god save our queue

I would prefer to record GNDT to track the area charted using the same unit (degrees). And btw, don’t you think the same degrees cannot be charted twice?
