Approximating Shortest Paths on Weighted Polyhedral Surfaces

  title={Approximating Shortest Paths on Weighted Polyhedral Surfaces},
  author={Mark Lanthier and Anil Maheshwari and J{\"o}rg-R{\"u}diger Sack},
One common problem in computational geometry is that of computing shortest paths between two points in a constrained domain. In the context of Geographical Information Systems (GIS), terrains are often modeled as Triangular Irregular Networks (TIN) which are a special class on non-convex polyhedra. It is often necessary to compute shortest paths on the TIN surface which takes into account various weights according to the terrain features. We have developed algorithms to compute approximations… CONTINUE READING
