## README
Welcome to pg-coordtransform 👋
> 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
```sql
-- 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
```
## How to use
```
