geos::geom::Coordinate
Coordinate is the lightweight class used to store coordinates.
Definition: Coordinate.h:60
geos::geom::LineString
Definition: LineString.h:70
geos::operation::linemerge::LineMergeGraph
A planar graph of edges that is analyzed to sew the edges together.
Definition: LineMergeGraph.h:59
geos
Basic namespace for all GEOS functionalities.
Definition: IndexedNestedRingTester.h:25
geos::planargraph::Node
A node in a PlanarGraph is a location where 0 or more Edge meet.
Definition: planargraph/Node.h:45
geos::planargraph::PlanarGraph
