Im working on making the WorldWind program as a player aid. I am making a custom SH3 campaign in an alternate reality and will be mapping the content on the WW globe. For example, there will be a submarine icon which is linked to the shortcut for SH3. While SP missions will start in port, you can use this player aide to map out MP missions. I havent figured out if there are command line parameters to start SH3 with a specific mission or saved game loaded. But its a start.
I will also be including content for a free flight sim, Flight Gear and possibly free 3D s/w like gmax and Blender.
For SH3 players, I have included the KM grid map. I am having a problem matching the land masses exactly which might be a projection problem. It is a work in progress. I will include a help file to explain how to change the lat/long of the icon to reflect your current location.
Other layers include terrain and shaded relief images:
