The Radial Topology Algorithm - A New Approach for Deriving 2.5D GIS Data Models
In this paper a new method for the combination of 2D GIS vector data and 2.5D DTM represented by triangulated irregular networks (TIN) to derive integrated triangular 2.5D object-b...

A new approach for a topographic feature-based characterization of digital elevation data
Triangular Irregular Network (TIN) and Regular Square Grid (RSG) are widely used for representing 2.5 dimensional spatial data. However, these models are not defined from the topo...

Surface Reconstruction Based on Lower Dimensional Localized Delaunay Triangulation
We present a fast, memory efficient algorithm that generates a manifold triangular mesh S passing through a set of unorganized points P R3 . Nothing is assumed about the geometry,...
