I think it would be nice if maps worked something like this.
- first, I really like the feeling to first discovery, so I am not sure I would like having maps for sail. So far I have not been really lost and was able to find my location within an hour or so.
- second, we can all use google maps but it would be nice if in game your personal map would be slowly generated as you discover an area. only adding to your map the area that you be see. This would make it so that if I sail south and run into a large island just north of South America, my map might only show a small coastline until I sail around it, If I don't sail around it then I will not know for sure if it is an island or the Coast Venezuela.
- third, navigators of the time could get a fairly accurate Latitude, and would have an idea of there longitude. I would like to see the ability to check for Latitude at night and have it be accurate to within say 1 or 2 deg. For longitude I think we could have something like this. when you leave a known port you have an accurate Longitude and for each day of in game at sea sailing you loose maybe one degree of accuracy so the number you get after 12 days at sea could be up to 12 degrees off. you could max this as something like 15 degrees or something. In real life they would try to log there speed and direction to keep a somewhat accurate number.
These are just a few of my thoughts on maps and navigation.
