基于PostgreSQL和PostGIS的坐标转换函数,支持点、线、面的WGS84和CGCS2000与GCJ02和BD09坐标系与之间互转。
Example
-- 如果转换后结果为null,查看geom的srid是否为4326或者4490 WGS84转GCJ02 select geoc_wgs84togcj02(geom) from test_table GCJ02转WGS84 select geoc_gcj02towgs84(geom) from test_table WGS84转BD09 select geoc_wgs84tobd09(geom) from test_table BD09转WGS84 select geoc_bd09towgs84(geom) from test_table CGCS2000转GCJ02 select geoc_cgcs2000togcj02(geom) from test_table GCJ02转CGCS2000 select geoc_gcj02tocgcs2000(geom) from test_table CGCS2000转BD09 select geoc_cgcs2000tobd09(geom) from test_table BD09转CGCS2000 select geoc_bd09tocgcs2000(geom) from test_table GCJ02转BD09 select geoc_gcj02tobd09(geom) from test_table BD09转GCJ02 select geoc_bd09togcj02(geom) from test_table
