| # ST_Transform |
| |
| Introduction: |
| |
| Transform the Spatial Reference System / Coordinate Reference System of A, from SourceCRS to TargetCRS. If the `SourceCRS` is not specified, CRS will be fetched from the geometry using [ST_SRID](ST_SRID.md). |
| |
| Since `v1.9.0`, Sedona supports multiple CRS formats including EPSG codes, WKT1, WKT2, PROJ strings, and PROJJSON. Grid files for high-accuracy datum transformations are also supported. |
| |
| !!!tip |
| For comprehensive details on supported CRS formats, grid file usage, and more examples, see [CRS Transformation](../CRS-Transformation.md). |
| |
| Format: |
| |
| ``` |
| ST_Transform (A: Geometry, SourceCRS: String, TargetCRS: String) |
| ``` |
| |
| ``` |
| ST_Transform (A: Geometry, TargetCRS: String) |
| ``` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.2.0` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_AsText(ST_Transform(ST_GeomFromText('POLYGON((170 50,170 72,-130 72,-130 50,170 50))'),'EPSG:4326', 'EPSG:32649')) |
| ``` |
| |
| Output: |
| |
| ``` |
| POLYGON ((8766047.980342899 17809098.336766362, 5122546.516721856 18580261.912528664, 3240775.0740796793 -13688660.50985159, 4556241.924514083 -12463044.21488129, 8766047.980342899 17809098.336766362)) |
