Abstract

In geographical information processing approximating the original surface from contour line data information is achievable through triangulation. Surface approximation by triangulation is treated as a combination problem of triangular elements in a polygon approximation of the original data. Conventional triangulation methods tend to be sequential, deterministic and triangulation decisions are made on localized evaluations disregarding the global picture. In this paper a novel and simple contour data triangulation scheme proposed by the authors is used to triangulate digitized contour data from a geographical map. The scheme is relatively technique independent and triangulates contour line data in a parallel manner.
