A key limitation of the picture shown here is that we can only portray the curvature of a 2-dimensional plane of an actual 3-dimensional space!

这里给出的图片局限性在于，我们只能通过一个二维图片来表现三维空间！

Map projection in cartography is a way to present a two-dimensional curved surface on a plane, such as a normal map. Figure 2 shows a Traverse Mercator projection.

绘图法中的地图投影方法可以在平面中表示一个两维的曲面，例如一个标准地图。

This gives a three dimensional model which is then projected onto one plane to give a 2 dimensional graphic (See figure 3a).

这给出了一个三维模型，然后到一个飞机预计将提供一个二维图形（参见图3a）。
