Topological spatial relation calculation in constrained Delaunay triangulation: an algebraic method
Topological spatial relation between spatial objects is a very important topic for spatial analysis, query and reasoning in Geographic Information Science (GIS). In this paper, an algebraic methodExpand
Describing and Calculating of Geometry Adjacency Relation with Voronoi Tessellation
The geometry adjacency relation with topology and metric based on Voronoi model is described and a local computing method (V2) of geometry adjACency upon on VAG is proposed, which takes distance as a foundational operator to ensure influence neighbors. Expand
