Update: July 2009 – The link below is dead. Here’s an interactive map of Second Life.
I found a google map of Second Life. The map is designed to help you find Voice Enabled SIMs [ areas of land that have the new voice feature.] But it’s not tremendously useful for that now, since almost all or all sims are voice enabled now. But the map is very cool, since it’s the only way I know to get an overview of the entire world of SL. The inworld map stops showing land icons beyond a certain zoom-out level.
The dense group of SIMS in the South of the map with the brown colored desert sims is an area called Azure Islands, which is an independent land owner in SL. I have had various properties in this area since I joined SL.
