After reading a thread wherein Moopf Murray posted an image of a landmass I'd only realized existed literally a few days before (when the land store opened and I was looking around). I was a bit confused on what exactly it was. (Obviously, I've figured it out since then.)
In the thread, I pointed out that I'd been living on the Atoll for almost six months without knowing what its official name is (I just found it while writing this post). I said that I've considered doing up a map of the SL world with the major landmasses labelled.
So, mostly for my own amusement, I am. I'm taking a bunch of screenshots of the world map, stuffing them all into one big image, making it a bit more attractive (read: manipulating colors and removing junk), and labelling things on it.
Basically, I'm labelling anything that looks big enough to bother with ... I probably won't bother with anything less than 3-4 sims unless it's Caledon (because I will be living there shortly), a Linden thing, or I otherwise know the place.
I'm not attempting to map the Simulator names -- slmaps.com already has links to that sort of info for most of the world. Rather, I'm trying to put down names to the continents and such, mostly so I know what the heck to call them. When people mention something like "Dreamland", others can go "Oh, yeah, I saw that on the map..." instead of having to track down what the heck people are talking about.
And labelling some of the more stable and important landmarks and locations (Welcome Area, Linden Village, the Great Wall, etc.). Think of it as my explorer's map.
The only problem with this idea is ... I don't actually know a lot of the information that I need.
I know these things:
* The Northern Continent is called Heterocera Atoll.
* The Southern Continent - For want of knowing the official name, I henceforth dub this land Sansara, which is mentioned on the History Wiki as one of the names that was contemplated for SL itself.
* The More Different Southern Continent (that's the one pictured in the thread above, and also the subject of some of the threads I link to below). In honor of the allusion I just made, plus the fact that there be dragons here, we could call it Rodgortlund!
Or something ... more creative.* Dreamland (I call it the Dreamland Archipelago, since it's not really a single landmass now.) I know where it is, but not the official borders ... I didn't have the patience to look up ALL of the islands Anshe owns and see where they were. So I just plopped a label down in that general area and called it it sufficient.

* Gamedev Archipelago - The diagonal line of Gamedev sims west of the atoll.
* Combat Archipelago - Rausch, Weapons Testing Sandbox, etc.
* Shermerville Island - Nine sims sitting Northeast of Sansara
* The Azure Islands - In the southwest. Mostly I know this because there's a screenshot in one of the threads linked below.
What I need:
* Feel free to correct me if I've gotten something official wrong. Of course, since I'm doing this primarily for my own amusement, I may decide to use what suits my tastes regardless.

* I gather that the two rectangular blocks of sims to the northeast and southeast of Sansara (and connected to it by void sims) were part of LL's recent experiements in land sale. But does anyone know what's going to happen to them? Part of another continent?
* I have a hard time exploring intriguing islands (or even getting their names) because the world map in SL invariably kills my internet connection if it is open for longer than approximately ten seconds, and I can't make links directly to them because I don't know their names (slmaps doesn't list them). If you are the owner of one of the larger groups of islands, a post with the official name and a screenshot of the relevant sims (with enough context so I can find them on my images), or better yet an SLURL would be helpful. In particular, there's the checkerboard west of Sandbox Island.
Of course, this could be completely pointless, since SL changes a lot, and because someone may well have already done it and I just hadn't heard. But I don't care.
