Class RequestGeometry

java.lang.Object
  org.deegree.ogcwebservices.wpvs.operation.RequestGeometry

Direct Known Subclasses:

ConeRequest, LineRequest

public abstract class RequestGeometry
extends java.lang.Object

This abstract class represents a geometry needed for Get3DFeatureInfoRequest. It contains the 3d geometry and its 2d projektion. The 2d geometry is required for WFS request, the 3d geometry for the final test of intersection.
