Method Detail

findObjectsToMerge

public static List<LocatedObject> findObjectsToMerge(LocatedObject obj,
                                                     Map<LocatedObject,Double> matches,
                                                     Set<LocatedObject> merged,
                                                     String labelKey)

Determines the objects to merge.

Parameters:

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

Returns:

the list of objects to merge

toGeometry

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.

Parameters:

obj - the object to convert

algorithm - the overlap algorithm to use

Returns:

the generated Gemoetry

mergeObjects

public static List<LocatedObject> mergeObjects(LoggingObject loggingObject,
                                               List<LocatedObject> objs,
                                               ObjectOverlap algorithm,
                                               String scoreKey,
                                               String labelKey,
                                               MergedScoreCalculation mergedScoreCalculation)

Merges the objects into a single on.

Parameters:

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

Returns:

the merged object
