public class ColumnClustering : IClusteringAlgorithm

The ColumnClustering type exposes the following members.

Public methodColumnClustering
Initializes a new instance of the ColumnClustering class
Public methodCalculateClusters
Calculates the clusters for a specified map and set of features.
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetQueryBounds
Get the required query bounds for calculating clusters for the given viewport.
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
First partitions the features into a grid of small sub clusters Where possible these sub clusters are combined into a grid of clusters. Edge sub clusters are not initially placed on the grid - instead they are merged into adjacent clusters in a second pass. This is so that the cluster labels do not have to be drawn a large distance from the centroid of the cluster.
