摘要
根据福州市区域内的三维框架网点,分别采用二维七参数转换模型和二维四参数转换模型,实现由WGS-84坐标系到福州地方坐标系的转换,并进行转换精度的统计与分析。结果表明,两者转换精度均符合要求,转换结果基本一致。
According to the 3 D framework in Fuzhou area, respectively using 2-D seven parameter conversion model and 2-D four parameter conversion model, this paper implemented the conversion from the WGS-84 coordinate system to the fuzhou city local plane rectangular coordinate system transformation, and analysed conversion accuracy The results showed that both the conversion accuracy can meet the requirements of engeneerings, the conversion results are basically the same.
