The Head-Body-Tail Intersection for Spatial Relations Between Directed Line Segments

Published: Jan 1, 2006 Author(s): Egenhofer, Max J., Kurata, Yohei Abstract: Directed line segments are fundamental geometric elements used to model through their spatial relations such concepts as divergence, confluence, and interference. A new model is developed that captures spatial relations between pairs of directed line segments through the intersections of the segments’ heads, bodies, and tails.
