      • findObjectsToMerge

        Determines the objects to merge.
        obj - the objects for which matches were located
        matches - the matching objects
        merged - the objects that have been merged already
        labelKey - the key in the metadata containing the label
        the list of objects to merge

        public static org.locationtech.jts.geom.Geometry toGeometry​(LocatedObject obj,
                                                                    ObjectOverlap algorithm)
        Turns the located object's polygon or bbox into a Geometry instance. Takes potential bbox fallback into account.
        obj - the object to convert
        algorithm - the overlap algorithm to use
        the generated Gemoetry

        Merges the objects into a single on.
        loggingObject - the project use for logging errors etc, can be null
        objs - the objects to merge
        algorithm - the overlap algorithm to use
        scoreKey - the meta-data key with the score
        labelKey - the meta-data key with the label
        mergedScoreCalculation - how to calculate the merged score
        the merged object
