该坐标系英文名称:China Geodetic Coordinate System 2000
EPSG代码:EPSG:4490
EPSG网站链接:http://epsg.io/4490
某些国外厂商的GIS软件可能缺省没有支持CGCS2000,所以需要自定义。在EPSG网站上面能够查到坐标系的WKT表示,如下:
GEOGCS["China Geodetic Coordinate System 2000", DATUM["China_2000", SPHEROID["CGCS2000",6378137,298.257222101, AUTHORITY["EPSG","1024"]], AUTHORITY["EPSG","1043"]], PRIMEM["Greenwich",0, AUTHORITY["EPSG","8901"]], UNIT["degree",0.0174532925199433, AUTHORITY["EPSG","9122"]], AUTHORITY["EPSG","4490"]]
如下图所示,EPSG网站也给出了主流GIS软件中定义该坐标系的方式,很省心,有木有?
