maps will be craftable items and atm the planned system is that at any point you stand you can create a token specific for that point, and later you or someone else can put it into the map and it will pop up as a waypoint.
Personally i would prefer a type of explorer system too, so you needed to mark down your location to a map piece before you could see it on the map, but again maps are still up for discussion, go to community hub for oort and see the thread ”minimap on/off, compass” that i started and read what the devs answered and also write what you would like specifically to see 😀
