摘要
分析了三种不同坐标转换方法的优缺点,通过广州市花都区测绘生产中使用的各种坐标系统成果进行验算比较,提出了平面坐标三种近似转换方法,从中选择出适合本地区大面积图形数据转换的坐标系统转换方法。
The article analyses the advantage and disadvantage of three different coordinates transformation methods that are based on be used all kinds of the coordinates system productions which have compared and checked among the mapping produce in Huadu district, Guangzhou. The article not only indicates three sorts of similar transformation methods to complanate coordinates but also chooses the methods of transformation for the coordinates systems which are adapted to the graphics digital transformation of the large superficial extent in local area.
