| 摘 要： | 利用几种典型的坐标转换模型对湖北省大地坐标库与GPS坐标库的坐标转换问题进行了分析.结果表明:若将湖北省作为一个整体进行坐标转换,其精度可以满足中、小比例尺测图和一般工程测量的需求;但是,若要满足更高的精度要求,则应根据湖北省地形进行分区转换.

| Abstract: | By using several kinds of typical coordinate conversion models,this paper analyzed the problems of coordinate conversion based on geodetic coordinate database and GPS coordinate database of Hubei province.The result showed that if taking Hubei province as the whole to make coordinate conversion,its precision could meet the needs of the medium-small scale mapping and the general engineering surveying.But if the higher precision was required to be satisfied with,the divisional conversion should be made based ... |
