Abstract
As manual interventions in conventional large scale terrain modeling process results in low efficiency, this paper proposes an automatic terrain modeling method (ATMM) aiming to reconstruct terrain meshes taking advantage of remote sensing images with few manual interventions. The modeling method includes acquiring and processing digital elevation model (DEM), establishing topological relations between spatial points and interpolating elevation. Definitions and basic properties of several existing Delaunay triangulations are discussed and the spatial points’ topologies are constructed with the Delaunay triangulation template in Computational Geometry Algorithms Library (CGAL). An algorithm efficiency validation on a terrain with 18750×18750 points demonstrates the ATMM is acceptably competent for accelerating the speed of terrain modeling procedure.
