public class StY extends UnaryScalarFunction
Extracts the y-coordinate from a point geometry. For cartesian geometries, the y-coordinate is the second coordinate. For geographic geometries, the y-coordinate is the latitude. The function `st_y` is defined in the OGC Simple Feature Access standard. Alternatively it is well described in PostGIS documentation at PostGIS:ST_Y.
