坐标系统转换程序设计+代码
本文中介绍了各种坐标系的基础理论知识，包括椭球的概念、基准的概念、坐标系建立的基本原理和常用的几种坐标系以及坐标转换的过程和程序设计等，最主要的还是研究大地坐标系和空间直角坐标系之间的转换关系以及大地坐标系和高斯平面坐标系之间的转换关系，首先在理论的基础上根据转换模型进行转换再进行程序设计，通过不断的调试最终完成转换的编程，目的是将它们转换到国家统一的坐标系中，方便实际生活中的应用。
本文选择了比较常用的vb语言来进行编写程序，设计一个简洁明的操作界面，从而实现各坐标系之间的转换过程。

Abstract Coordinates are closely related to human life. A precise location can be expressed in a variety of coordinates, and the most practical coordinate system is selected according to the economic environment conditions at that time. According to its different means, the coordinate system can be pided into geodetic coordinate, Cartesian coordinate, plane coordinate, local independent coordinate, etc.. At present, China's common coordinate system has Beijing 54 coordinate system, Xi'an 80 coordinate system, 2000 geodetic coordinate system, WGS-84 coordinate system, etc.. In the globalization of today, all the countries in the world are interlinked, for the convenience of life, need a unified standard for everyone to use, also coordinate system also need to unify. Therefore, it is necessary to convert between various coordinate systems, to meet the working needs.
This paper introduces the basic theoretical knowledge of all kinds of coordinates, the conversion relationship between including ellipsoid concept, basic concept, establishing the coordinate system the basic principle and several common coordinate system and coordinate conversion process and program design, the main or the earth coordinate system and spatial straight angle coordinate system and geodetic coordinate system and Gauss plane coordinate system conversion, first of all in theory according to the conversion model of conversion of program design, through continuous debugging finally completed conversion of programming. The aim is to convert them to the national unified coordinate system, and to facilitate the application of real life..
In this paper, it chose to a common software VB language to write a program, design a simple and clear interface, so as to realize the conversion between the coordinate system.
Key words：geodetic coordinates coordinate translation Gauss projection
