Since I am going to be putting up more and more maps and stories to go with them I shall describe what you are looking at besides pretty colors. For without a key to interpret the maps they are kind of useless.
There are going to be four types of maps: Biome, Physical, Political, and Historical. Though I might add more types in the future. First type is the biome maps. A biome is an area with certain climates that support certain plants, animals, and weather. It's the most colorful map type and the most useful for RPing as just a glance you can tell what the weather and setting will be.
(oooo colorful...)
This is a Biome chart. Due to the way Fractile Terrains computes the map from the data through this image it is flipped from what is usually found. The x-axis is temperature from around -15C to 25C left to right. The y-axis is how much precipitation the land gets from the top which is zero to greater than 250cm per year at the bottom. The diagonal across the middle is what is allowed by nature. I colored it below that line so white or black spots didn't appear in the maps in case an area got more rain than it 'should'.
There are four general trends in the colors you may notice. From left to right they are Polar, Arctic, Temperate, and Tropical. I'll attempt to provide a general description of the climate and biome.
Polar consists of Ice (White) on the far left, Polar Desert (Grey) on the top, and Tundra (Light Teal) ontop of the grey. The other two below Tundra are nameless cause they don't exist in nature. I'd like to call them Polar Swamp and Polar Lakes. Ice Is just that. Ice and lots of it. Thick Greenland or Antarctica Icecaps. No Polar Bears or Penguins here. Most you get is some lichen, the polar microscopic type. No life to be found here. Make sure to bring lots of food and wood, or better yet, just stay away.
Polar Desert! (Grey) This is a desert that is cold. Really cold. So cold and dry it can't snow. Nothing but wind swept rocks and glaciers coming down from the icecaps that are probably nearby. Best to stay away. Think the rocky part of Greenland. Though! If there is an ocean nearby it will have lots of fish and life.
Tundra! (Light Teal) This is the only Polar biome with actual life. There are no trees, barely any grass or shrubs. Only the hardiest ponies can survive out here. Though Caribou/reindeer do make this their summer home. In the Winter is a snow swept wasteland, but in summer, for however brief it is, grass, shrubs, and plants bloom. Think Siberia, Northern Canada and Alaska. Not the pretty tree part that's farther south.
Ohhh and it's late... I'll post this and start up Arctic/Cold Temperate tomarrow. Night and thanks for reading! I do have more maps. I brushed up the Crown Lands and have them all ready to post but first I need to teach people who want to read them how to. This will be a long project and I thank you for waiting.
Twilight approves learning!
Arctic Biomes
Arctic is the next column and actually get trees and complex climates. From the top, Polar Desert (Grey; see Polar Climates above), Cold Shrubland (Dark Blue), Cold Grassland (Light Blue), Cold Savannah (Blue), Taiga (or Northern/Cold Forests; Dark Teal), Cold Rainforest (Teal). Cold Shrubland (Drak Blue) is a cold semi-desert. Warm summers and extremely cold winters. Few living things and very much like tundra, except less life usually. (Tundra covers a wide range) Much like the Gobi Desert. Cold Grassland (Light Blue) covers a real grassland that has really cold and snowy winters. Think northern central Canada, the Prairie Provinces or Russia.
Cold Savannah (Blue) is the area between the grasslands and the forests. Trees do grow here but this far poleward they will be pines. Mostly grass with a few stands of trees here and there. Canada. Very Cold winters and Warm Summers.
Taiga (Dark Teal) or Cold Forests are the pine forests of the north. Climate can range from mild cool all year like northern British Columbia to warm summers and frigid winters more inland.
Cold Rainforests (Teal) are rare. They get a lot of moisture compaired to other Arctic and Polar biomes. Usually considered the same as Taiga but with more rain and snow. Usually a bit warmer to. Other arctic biomes below this one should be considered 'fake' or unnatural.
Here is the Biome pic edited into the original chart is got the information from: (So you can see what I am talking about.)
