一种实现西安80坐标系地形图向北京54坐标系快速转换的简易方法

An easy method to resolve problems of transformation between Xi'an1980 and Beijing1954 coordinate system

本文针对GIS应用中经常遇到的西安80和北京54坐标之间的转换问题,提出了实现两种坐标系地形图相互转换的简易方法。首先利用MAPGIS软件自动生成西安80矢量标准图框,根据坐标改正参数,将西安80坐标系图框转换到北京54坐标系,再以它为参照基准,对地形图进行逐格网纠正,实现西安80坐标系地形图向北京54坐标系的转换。该方法操作简单,易于实现,非常适合于非测绘人员使用。

Especially, to resolve problems of transformation between Beijing1954 and Xi＇an1980 coordinate system, this paper brought forward an easy and feasible transformation method. Firstly, it automatically generated vector standard frame of Xi＇an1980 coordinate system using software of MAPGIS. Secondly, according to coordinate revised parameters, vector standard frame of Xi＇an1980 coordinate system was transformed into Beijing1954 coordinate system, then carry out correcting for topographic map grid by grid referring to vector standard frame of Beijing1954 coordinate system. This method operates simply and easily performance, which is very suitable for some persons who don＇t specialize in survey.
