通过研究得出，将地球上各种地理事物与现象表示到平面上，需要采取一系列数学变换，才能使地面上的点与平面上的相应点建立起对应关系，从而才有可能反映出它们的位置、距离、方向、面积、形状及数量大小关系。地图之所以能在平面上反映出球面上事物与现象的空间准确位置和相互关系，就是由于它经过了地图投影的转换。通过研究地图投影变换问题，可以为基于离散网格的数据管理和建模应用提供很好的投影变换基础。

The results of the study conclude that: when we express the geographical things and phenomena on the plane , a series mathematical transformation would be necessary .Thereby , the correspondence of points on the ground and plane could set up .The po-sition, distance, direction, area, shape and quantity could be known .The reason map could express the definite spatial location and the relationships of things and a phenomenon is that it has projection transformation .The data management and modeling application of discrete surface based on mesh would provide better foundation theory by studying the map projection transformation issues .
