Method Detail

intersects

public static boolean intersects(Node node1,
                 Node node2)
                          throws TransformException

Determines whether or not two GML geometry representations spatially intersect. The result indicates whether or not the two geometries have at least one point in common; more specifically:

 a.Intersects(b) <==> ! a.Disjoint(b)
 

If the geometry representations have different CRS references, a coordinate transformation operation is attempted.

Parameters:

node1 - An Element node representing a GML geometry object.

node2 - An Element node representing another GML geometry object.

Returns:

true if the geometries are not disjoint; false otherwise.

Throws:

TransformException - If a coordinate transformation operation fails.
