public class MergeSpatialClusters
extends MergeBase

Merges spatially-adjacent objects using the DBScan clustering algorithm.

The features passed to DBSCAN are based on:

• Euclidian distance
• an @{code eps} (max distance for neighborhood connection) where distance is less than maxDistanceCOG (calculated on XY resolution)

                                   throws ProvisionFailedException

Description copied from class: ObjectCollectionProviderUnary

Creates a ObjectCollection given the entity provided by the delegate.

Specified by:

createFromObjects in class ObjectCollectionProviderUnary

Parameters:

objectsToMerge - the entity provided by the delegate.

Returns:

the created ObjectCollection that is returned by the provider.

Throws:
