摘　　要：随着社会的发展,为了满足经济建设的需要,许多城市都建立了自己的地方独立坐标系统,如果实现独立坐标系向和高斯坐标系之间的相互转换,将能更好的利用现有的一些空间信息资料,满足不同用户的需要,对提高经济效益,具有一定的现实意义。本文首先介绍了坐标系的基础理论和高斯投影的方法及其高斯投影坐标计算过程,在这些基础理论的基础上论述了建立地方独立坐标系的原因、原则、理论、类型和方法。并对地方独立坐标系的类型和建立方法进行了归纳,比较了它们各自的有缺点,从而确定一种适合本地区的独立坐标系统。然后,分别基于相似转换法、多项式逼近法和椭球变换法详细编写了独立坐标系向高斯坐标系的转换过程。With the development of society,in order to meet the needs of economic construction,many cities have established their own independent coordinate system,if the independent coordinate system can be converted into the Gaussian system,it will be able to better use of existing information on some of the space to meet the needs of different users and improve the economic efficiency.This has a certain practical significance.This article introduces the basic theory of the coordinate system and a method of Gauss projection coordinates calculation process.It discusses the establishment of local coordinate system independent of the reasons,principles,theories,types and methods in the basis of a theoretical.The type of Local coordinate system has its features,in order to determine the suitability of a region,we should compared their respective weaknesses with each other.Then,I write the conversion process based on the similar conversion method,polynomial approximation and detail ellipsoid.
