org.h2gis.api.DeterministicScalarFunction
org.h2gis.functions.spatial.distance.ST_LocateAlong
All Implemented Interfaces:
org.h2gis.api.Function, org.h2gis.api.ScalarFunction
public class ST_LocateAlong extends org.h2gis.api.DeterministicScalarFunction
ST_LocateAlong returns a MULTIPOINT containing points along the line segments of the given geometry matching the specified segment length fraction and offset distance. A positive offset places the point to the left of the segment (with the ordering given by Coordinate traversal); a negative offset to the right. For areal elements, only exterior rings are supported.
