Class ConvexHullMapReduce

java.lang.Object

org.locationtech.geowave.analytic.mapreduce.clustering.ConvexHullMapReduce

public class ConvexHullMapReduce
extends Object

Compute the convex hull over all points associated with each centroid. Each hull is sent to output as a simple features.

Properties:

"ConvexHullMapReduce.Hull.DataTypeId" - Id of the data type to store the the polygons as simple features - defaults to "convex_hull"

"ConvexHullMapReduce.Hull.ProjectionClass" - instance of Projection

"ConvexHullMapReduce.Hull.IndexId" - The Index ID used for output simple features.

"ConvexHullMapReduce.Hull.WrapperFactoryClass" -> AnalyticItemWrapperFactory to group and level associated with each entry
