Status: I've placed icons and labels.
Here is the current state of the map. While I may do a little revising to fix errors and optimize, the base map is essentially done.
New Features+I added city icons for every city I could find in Atlantis. This includes nine cities that aren't on any canon maps. +The three extra Metzla cities are named in the text, but their locations are "nearby Xym", so I put them in high ground (since their hives are artificial mountains) around a valley.
+The Kittani have three cities half the size of Ki-Talan, but aren't named, and have no location data other than "...within a 200-mile radius of Ki-Talan". I made two of them major cities (over the 3-million mark, hence the eye icons) and one minor (under the 3-million mark). I placed a major Kittani city at the sea for the purposes of being a major hub for maritime trade, since the east coast of Atlantis seems to be fairly stable. The smaller Kittani city I also put on the coast, but further out, and reasoned that it's more of a maritime military base for the Kittani. The last Kittani city I put inland, in its own sub-valley, where two major tributaries to the southern river system come together.
+The three small cities in the north are described in the Azlum section as being minor cities which are 100 miles to the south, southeast, and east of Azlum.
+I added labels for the natural geography, regions, and cities. +I gave the natural and regional labels a transparent look and curved them with the terrain they label, since they're large and I don't want to obscure the terrain they represent.
+I gave the city labels a solid-gold look, since the icons they go with are solid too. Gold seems an apt choice given the whole megaversal market angle of Splynncryth and his off-the-scale wealth.
+I added in a scale for the map. Since no scale is provided on any canon Atlantis maps, I used Google Maps, which lists the distance from Bermuda to the Azores as 2100 miles (3400 km). On the map, this is 2950 pixels. Therefore, a distance of 500 miles = 800 km =714 pixels.
+I threw in a placeholder north-seeking arrow. It'll hold the place for a fancier-looking compass rose I'll try to dream up later. Most of my compass roses to date have been are very simple, but this project calls for something a bit fancier.
+I added in some geographic references on the map (this way to Africa, etc) since North America, Europe, and Africa aren't far off the map. I liked these features on the WB2, page 38 map. They don't look all that special, but I find they help me establish a good frame of reference. They're all over a bunch of otherwise-unmarked water, anyway.
+I added in borders for the Refuge, Preserves, and Gargoyle Kingdom. This makes for a somewhat incomplete look. Though the text suggests that the Kittani and Metzla have their own regions, these are not marked. Also, the Gargoyle Kingdoms
New issues with the map! I could use some suggestions for how to deal with these.
-I'm unsatisfied with the borders between regions. They look sloppy, and I'm not sure how to fix them yet.
-There's still a major city unaccounted for in The Valley. There are 7 total, according to WB2, but only some are described. I have accounted for most of the rest through intuitive guesswork, but I'm not sure whether or not I should just throw in another eyeball somewhere logical and label it "City". Maybe where the southern outlet of The Valley reaches the sea? Or is it better to stick to what's specifically mentioned in WB2?
-There are 11 minor cities in The Valley that are still unaccounted for. There are 20 total, according to WB2. Do I make more educated guesses and label them "City", or should I stick to what's specifically mentioned in WB2?
-The Azores. I could individually mark these with names from current Azores islands, but I have no clue which is which. These islands don't even approximately match the size, number, and shape of the real-life archipeligo. Do I do some educated guesswork here, or do I just leave it be, since there are loads of unnamed natural features on this map anyway?
-The Great Stone Mountains are unmarked. I actually tried marking the range, but that didn't turn out great due to its twisting shape, which requires part of the label to wind up a little upside-down. Also, this label's length caused it to overrun the Gargoyle Kingdom. Since the other mountain range isn't labeled (or named in WB2, for that matter), I can live with it, unless someone has a better idea. I'd also like to label individual mountains, but Mount Doom is the only one with a precise location (and it would overlap with Kii-Kyl), and many of the others are too wordy to fit nicely on the map.
Though the cartography and research are pretty much done now, there's still plenty to do, including making a compass rose, making a legend, and making a border. I'll have to think on how I'm going to do them.
