About the Map
The Planet Earth's shape is similar to a Sphere, but maps are Flat.
|In this case I used a special type of Cylindrical Projection called Plate Carrée, or Equirectangular Projection, because it works a bit like an x-y graph (which made the mathematics a lot easier)|
|(It makes the land near the poles squashed-and-stretched, but it works well for most places!)|
