Very rudimentary grid map that covers Wright and Yeager. Proof of concept. Placement of the islands turned out to be not too accurate. If someone has the time, please feel free to create a better version with higher precision.
This (better version of this) can be used for determining the course for FT controlled self-driving ships or aircrafts (see latest builds by 11qaxc (link).

Example of use - my bomber flight plan for AI F-105s. (Still wip)

Due to the incorrect placement of the islands/difficulty to tell what landmarks are where, I had to make a lot of adjustments to make this flight plan work. Really need a better version, preferably one that covers the entire map.

I have an idea to create one though. You make a version that covers smaller area with smaller units (maybe one that counts XZ by 100 or even 10m increment), survey & chart the islands, then overlay the thing on top of this one to scale.
