 Landmarks provide a powerful method of representing significant locations within space or locations defined by the model. Landmarks are created by either specifying a location in a segment coordinate system or by transforming markers or other landmarks into a significant location. Landmarks provide a powerful method of representing significant locations within space or locations defined by the model.
