地理坐标

Based on these theories, it develops a GIS map projection software using Visual C++ as a platform. The software consists of two parts: analytical ordinal transformation and analytical athwart transformation. Analytical athwart transformation implements map projective transformation with coefficients obtained through numerical method, which is also the main idea of this paper. Map projective transformation process is illustrated with the examples of Mercator projection and conic projection.

地图投影建立了平面上的点(用平面直角坐标或者极坐标表示)和地球表面上的点之间的函数关系，而地理信息系统以平面直角坐标形式通过计算机图形学的方法表示2维或3维地理空间信息，因此，地图投影起到了地球空间与地理信息系统之间的坐标转换的桥梁作用[1]。

The system can be used alone or be integrated into other GIS systems to enhance their map projection function. map projection ; map projective transformation ; analytical ordinal transformation ; analytical athwart transformation

在GIS应用系统中往往需要管理多种不同地图的地理数据，这些不同投影的数据在进行地理空间分析或信息复合时需要坐标同化，需要将不同投影的坐标统一到同一个坐标空间中，随着G

Starting from the view point of the characterization of geological objectives, interpretation is made of the plane coordinate conversion from both its physical and geometrical significance.

从地理对象描述角度出发，对平面坐标转换进行了物理意义和几何意义的解释，并得到概括的数学模型，建立2类转换方法的参数计算公式。
