Help with Hexploration activity "Map the Area"!

[SaltySpitt00n]

Hey everyone, my DM and I were looking at the Hexploration rules so we could be better equipped for our Kingmaker game, and we couldn't really parse out what the use for the "Map the Area" activity was for. More specifically, what does it mean by " the DC of any check to navigate that hex is reduced by 2,"?

Reading through it, it doesn't look like the base framework for hexploration has any checks to navigate a hex.

My guess is that the benefit is for any particular features that the GM gives to a hex that adds a navigation check.

For example, a river hex could have rapids in it that the GM decides takes a DC 20 Piloting or DC 25 Survival/Athletics check to navigate. And has some penalty if you fail. Then the map of the hex would give you the -2 DC to the check to pass the rapids without penalty.
