CC-Modeler: A topology generator for 3-D city models
3-D City models topology generator building reconstruction visualization
2016/5/20
In this paper, we introduce a semi-automated topology generator for 3-D objects, CC-Modeler (CyberCity Modeler).Given the data as point clouds measured on Analytical Plotters or Digital Stations, we p...
Measurements of Forest Inventory Parameters on Terrestrial Laser Scanning Data Using Digital Geometry and Topology
digital geometry digital topology image processing skeletonization
2015/12/8
This paper gives some mathematical methods for the automatic analysis and determination of forest management parameters in particular for the measurements of geometrical sizes on terrestrial scanning ...
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 ...
This paper reviews 3D topology within Land Administration Domain Model (LADM) international standard. It is important to review characteristic of the different 3D topological models and to choose the ...
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 ...
AUTOMATIC EXTRACTION AND TOPOLOGY RECONSTRUCTION OF URBAN VIADUCTS FROM LIDAR DATA
Airborne LiDAR Point Cloud Overpass Urban Viaducts Recognition Topology Reconstruction
2015/9/21
Urban viaducts are important infrastructures for the transportation system of a city. In this paper, an original method is proposed to automatically extract urban viaducts and reconstruct topology of ...
AN INTEGRATED MODEL FOR FUZZY TOPOLOGY AND QUALITATIVE DISTANCE FOR DISCRETE SPACE
topologic relation model discrete space fuzzy region
2015/8/10
The topological relationship of disjoint is ubiquitous in physical world, while the traditional topological relationship models do not take more considerations about it. Point set topology is exhausti...
Traditional polygon-arc-node topological relationships (TRs) is standard in vector GIS. That has been explicitly represented by many commercial GIS systems. In the case of Intelligent Transportation S...
AUTOMATIC TOPOLOGY DERIVATION FROM IFC BUILDING MODEL FOR IN-DOOR INTELLIGENT NAVIGATION
IFC Geometry-Semantics-based Topology Derivation Navigation
2015/5/21
With the goal to achieve an accuracy navigation within the building environment, it is critical to explore a feasible way for building the connectivity relationships among 3D geographical features cal...
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...
