摘要
本文探讨了等面积投影仿射变换的理论和方法,包括:仿射变换等面积投影坐标、仿射变换面积元素的一般方法,并对一些常用的等面积投影进行了仿射变换举例。从等面积投影仿射变换中可得到具有很大实用价值的改良等面积投影,其具有很大的概括性和灵活性,在地图设计和计算机屏幕地图设计中有着广阔地应用前景。
This paper discusses the theory and method of affine transformation of equal area projection. It includes the general method of affine transformation of equal area project ion coordinates and area element togather with examples about affine transformation of some conventional equal area projections. From these examples, we can find that affine transformation of equal area projections keeps not only a large utility value but also certain generalized meaning.lt has a wide practical prospect in map design and comput er mapping.
