I made a thing: PlanetSide 2 map It's a full map of all three continents with all sectors. For Indar, there is also pins for the locations of many terminals, capture areas and such. There is also a basic "tactics planning" feature ("Custom Map" tab) which you can use to draw arrows and circles on the map. Contributing pins and saving custom maps requires a login. Parts of this are very much work-in-progress (more features for the planning thing for example), but the main map features and adding location pins should work. Any feedback is most welcome!
Thanks. The text is sized automatically to the shape of the sectors, but yeah it is a tad big in places - I need to fiddle with the algorithm so it works better
