ST_Transform

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. 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.

For comprehensive details on supported CRS formats, grid file usage, and more examples, see CRS Transformation.
