【摘要】 随着"走出去"战略的稳步实施,国内地很多勘单位都开展了境外矿产资源勘查,而在非洲大部分国家采取的是UTM投影,ARC1950椭球参数,而我国一般采用高斯-克吕格投影。通过使用MapGIS投影变换可以快速地将经纬度坐标落到相应比例尺的图幅上。更多还原

【Abstract】 With the steadily implement of the "going abroad" strategy, many units of exploration have carried out exploration of mineral resources, but in most African countries, a UTM projection, ARC1950 ellipsoid parameters was adopted, while Gauss- Kruger projection was adopted in China. By using MapGIS projection transformation, the longitude and latitude coordinates can be quickly put on the map of the corresponding scale..更多还原
