In order to promote the construction of digital geo-spatial framework in China and accelerate the construction of informatization mapping system, three-dimensional geographic information model emerged...
This paper investigates the problems of cylinder fitting in laser scanning three-dimensional Point Cloud Data (PCD). Most existing methods require full cylinder data, do not study the presence of outl...
Structural complexity in ecosystems creates an assortment of microhabitat types and has been shown to support greater diversity and abundance of associated organisms. The 3D structure of an environmen...
Recent advances in automation of photogrammetric 3D modelling software packages have stimulated interest in reconstructing highly accurate 3D object geometry in unconventional environments such as und...
This paper describes the use of terrestrial laser scanning for the full three-dimensional (3D) recording of historical monument, known as the Bastion Middleburg. The monument is located in Melaka, Mal...
The paper presents a very straightforward and effective algorithm to convert a space partitioning, made up of polyhedral objects, into a 3D block of voxels, which is fully occupied, i.e. in which ever...
Remote sensing via LiDAR (Light Detection And Ranging) has proven extremely useful in both Earth science and hazard related studies. Surveys taken before and after an earthquake for example, can provi...
Computational modelling of extreme particle and fluid flow events can provide increased understanding of their post-initiation course. For the prediction of fluid events such as dam breaks we use the ...
The traditional videometrics technique is usually adopted to measure the relative position and pose between the intervisible objects, and is invalid for measuring the three-dimensional position, pose...
A working integration of three-dimensional models with geo-referenced database holds great promise for large scale spatial study. In the past, the work was separated and difficult to combine between g...
Cadastre, was used for proposing land tax at the first time, is defined as being geographical information systems which modelling between human and land relationships and cadastre turns into multi-lay...
In this paper, a three-dimensional error model of grid digital elevation model (DEM) is proposed based on the reconstructed contours. Though analyzing the construction of three-dimensional error model...
Building reconstruction is one of the most difficult and important 3D modelling problems for urban environment. In this paper, we develop an approach using minimum number of basic geometric elements t...
Three Dimensional City Model (3DCM) research becomes a hot area in GIS field in recent years. The 3DCM research also has great significance in traffic, land, mine, surveying and mapping, and other fie...
Landslide hazards are one of the major natural hazards. It is difficult not only to get the integrated and accurate landslide datum but also to monitor and predict the landslide. This paper introduces...
