As far as I can establish there are no officlal detailed maps of Second life available. There was an effort made a few years ago, which i was happy to buy. But the promised updates-soon, never eventuated.
My interest is in sailing primarily, but also in general exploration. From my limited knowledge this seems to be a capability that the moles must already have in some form .
I'd like to see an uptodate map of Second life, at least to sim level detail, with indications whether they supported sailing or not (for ocean sims) and with public routes marked on lands.
Maps are works of art, as well as essential tools, in SL as much as RL. Please consider making an offical map of the world
