Topological Data Modelling for 3D GIS
3D data modelling is one of the key problems within research works of 3D GIS. This paper focused on the research of a topological model based on space partition for 3D GIS. Firstly the formal definition of 3D spatial features were given. Then the methods for calculating topological properties to support simplexes topologically equivalent to an n-manifold with (n-1)-pseudomanifold boundary cycle...
متن کاملThe role of DBMS in the new generation GIS architecture
Data Types (ADTs). This architecture is more beneficial for the integrity and consistency of the data. This chapter is devoted to the role of DBMS in new generation GIS architecture and focuses on the manner spatial data can be managed, i.e., stored and analysed, in DBMSs. Two important aspects of DBMS functionality are addressed in detail, i.e., spatial models and spatial analysis. Special att...

This paper discusses the making of three-dimensional geospatial data infrastructure (3D GDI) for Malaysia. The main component of the initiative is 3D city models with CityGML as the standard for data modelling, transfer and exchange. Various aspects of 3D city modelling especially on the construction of the models and texturing of facades via dynamic pulse function are described. The generated ...
متن کاملTarget detection Bridge Modelling using Point Cloud Segmentation Obtained from Photogrameric UAV
In recent years, great efforts have been made to generate 3D models of urban structures in photogrammetry and remote sensing. 3D reconstruction of the bridge, as one of the most important urban structures in transportation systems, has been neglected because of its geometric and structural complexity. Due to the UAV technology development in spatial data acquisition, in this study, the point cl...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملIntegration of Gis and Bim for Indoor Geovisual Analytics
This paper presents an endeavour of integration of GIS (Geographical Information System) and BIM (Building Information Modelling) for indoor geovisual analytics. The merits of two types of technologies, GIS and BIM are firstly analysed in the context of indoor environment. GIS has well-developed capabilities of spatial analysis such as network analysis, while BIM has the advantages for indoor 3...
