So the standard map size is 600 nmi x 600 nmi. The coordinates correspond to miles from the TOP LEFT corner of the map in the mission editor.
So, this line:
Quote:
LINE 70.727631 393.757446 57.436459 393.175690
|
goes from (70.72, 393.76) to (57.436, 393.1757)
(70.72, 393.76) means 70.72 miles east of the top left corner, 393.76 miles south of the top left corner, etc. etc.
(0,0) is the top left, (600,0) is the top right, (600,600) is the bottom right, (0,600) is the bottom left.
So, to translate these "map coordinates" into latitude and longitude is not a trivial endeavor. A friend and I made a program a while back to triangulate buoy contacts for you, and it could be modified to do this process of converting LAT/LON to Dangerous Waters "map coordinates".
This website here could help you out, I used it to develop my program:
