Coordinate is the lightweight class used to store coordinates.
Definition: Coordinate.h:60
Basic namespace for all GEOS functionalities.
Definition: IndexedNestedRingTester.h:25
Definition: geomgraph/Node.h:62
Creates nodes for use in the geomgraph::PlanarGraph constructed during overlay operations. NOTE: also used by operation::valid.
