Class SpatialRelationOp

java.lang.Object
org.openjump.core.attributeoperations.SpatialRelationOp
public class SpatialRelationOp extends Object
Contains methods to extract sets of features which fullfill some spatial criterion.

notes:

  • use "intersects" only for polygon geometries (condition intersection area > 0)
  • "contains" can be used for polygons and points (centroid from polygon is calculated)
