3D Spatial Operations for Geo-DBMS - Geometry VS. Topology
Spatial Database Geometry Query Three-dimensional GIS
2015/12/2
Geo-DBMS becomes very important medium for GIS as it can handle and manage (e.g. retrieve and update) large volume of spatial data. Providing 3D spatial database with appropriate operation tools such ...
The Basic Topology Issues on Spherical Surface Quaternary Triangular Mesh
SGDM Manifold SQTM Spherical Surface Digital Topology Spherical Surface Topology Paradox
2015/10/9
SGDM (Sphere Grid Data Model) is an efficient method to deal with the global data because of the advantages of multi-resolution
and hierarchy. However, SGDM has no distinct descriptions and lack of ...
A RESEARCH ON THE HIERARCHY AND COMPLETENESS OF ROOF TOPOLOGY FOR ROBUST BUILDING RECONSTRUCTION FROM AIRBORNE POINT CLOUD
3D Building Reconstruction Point Cloud Level of Details Roof Topology Graph Topology Completeness
2015/5/21
In this work, we concentrate on the hierarchy and completeness of roof topology, and the aim is to avoid or correct the errors in roof topology. The hierarchy of topology is expressed by the hierarchi...
