ST_Transform

Introduction:

Transform the Spatial Reference System / Coordinate Reference System of A, from SourceCRS to TargetCRS.

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 examples, see the Spark SQL CRS Transformation documentation.

Format:

ST_Transform (A: Geometry, SourceCRS: String, TargetCRS: String)

Since: v1.2.0

Example:

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))
