Graduated Symbol Map
As you think of Graduated Symbol Map, exactly what you thinking of? In essence a map is a representation of a topology or function. To get example a formula such as X=2Y maps a worth of Y to each value of A. Of course everybody knows that mathematicians are weird and sometimes hard to understand but they have you ever seen a schematic map of a subway (underground railway) system? Perhaps you have ever seen the same network of rails specified on a more "normal" Graduated Symbol Map of metropolis in which it is located? Different Graduated Symbol Map of the extremely same thing can look quite different.
As you make a Graduated Symbol Map of your flat area - a "plan" or "elevation" - things are quite simple, but when you make an effort to map a larger area, including the surface of an whole planet, things can get quite complicated if you would like your map to be toned. It really is all very well to make a world, but try turning the top of that globe into a set Graduated Symbol Map! Yikes!
However you begin it, you ending plan edge-effects. As I write this post I am actually engaged in programming map-generating programs designed to generate maps of fictional landscapes. I happen to be examining the map-generators that are included in the free, open-source (GNU GPL licensed) strategy game, FreeCiv. Edge results are extremely apparent in such maps. The Graduated Symbol Map are basically rectangular, but you can choose to acquire them act like cylinders by "wrapping" left to right or top to lower side, or you can also have "wrap" in both guidelines. Most often people make a decision on "wrap" only kept to right, and stop the best and bottom with "polar regions". Such simplified "wrapping" makes for quite extreme distortion though if you try it out with a real Graduated Symbol Map on the planet!
