  journal={Transactions in GIS},
Topology and its various benefits are well understood within the context of 2D Geographical Information Systems. However, requirements in three‐dimensional (3D) applications have yet to be defined, with factors such as lack of users’ familiarity with the potential of such systems impeding this process. In this paper, we identify and review a number of requirements for topology in 3D applications. The review utilises existing topological frameworks and data models as a starting point. Three key… 

Functionality and performance : two important considerations when implementing topology in 3D GIS

This thesis contributes to the understanding of the use of topology in analysing 3D spatial data, focussing in particular on two aspects of the problem - what binary topological analysis

The 3D Voronoi Diagram: A Tool for the Modelling of Geoscientific Datasets

This paper presents an alternative solution for the modelling of geoscientific datasets: the Voronoi diagram (VD) and its dual the Delaunay tetrahedralization (DT), and shows that it has many advantages over already existing models/structures for analysing and extracting meaningful information from datasets.

Working Group IV — Analysis — Position Paper: Spatial Data Analysis in 3D GIS

It is necessary to find out whether the developed 3D data models are designed for 3D spatial analysis, as different data models might be suitable for the execution of specific tasks but not others.


This paper describes phases of the development and results of an experimental structure of numerical cartography, at medium and large scale, to be used in GIS and to be proposed as a national

3D Data and Model Management for the Geosciences with Particular Emphasis on Topology and Time

of the Doctoral Thesis The doctoral thesis deals with the examination of methods for topological data handling, as well as designing and implementing a toolkit for the geosciences for management of

Towards a Property Registry 3D Model in Portugal: Preliminary Case Study Implementation Tests

The authors seek to show that there is room though for further investigation on the suitability of a 3D modelling approach, incorporating both topological-geometric representation and legal/administrative components, capable of handling the overall multipurpose cadastral reality in Portugal.

Requirements and implementation issues for a topology component in 3D geo-databases

Requirements of a topology component and first implementation issues for modeling and managing topological objects in a 3D geo-database are presented.

Topological information extraction from buildings in CityGML

It was found that the topological information extracted from the geometric structure of CityGML was limited to the locality of the object in question and could not extend beyond the dimension of the primitive.



The Balance Between Geometry and Topology

The design and implementation of a topologically structured management at the DBMS level is described, which supports the best of both worlds: on the one hand there are advantages of the topological structure (no redundancy) and on the other hand the ease of explicit geometric primitives in querying, analysis and presentation is available.

Support for visualisation and animation in a scalable 3D gis environment - motivation, concepts and implementation

Why 3D GIS technologies are a key factor in establishing and maintaining large-scale, reality-based 3D geoinformation services is outlined and specific features which should be provided by such GIS in order to support the efficient visualisation and animation of realitybased landscape and city models are discussed.

Topological Data Modelling for 3 D GIS

The formal framework to describe the topological relationships between 3D spatial features was given and the topology model based on geometric structure of 3Datial features was presented.

Topology revisited: representing spatial relations

A data structure that can represent proximal and directional spatial relations, in addition to topological relationships, is described, which allows a broader set of functional relationships and connections between geographical features to be explicitly represented.

Towards a 3D cadastre: where do cadastral needs and technical possibilities meet?

Development of a 3D GIS based on the 3D modeller Gocad

A set of topological and directional query tools, and a legend have been implemented as a prototype version in the Gocad 3D modeller to determine the spatial, temporal, and structural relationships between the modelled geological objects and their consistency.

3D Geographic Reconstruction and Visualization Techniques Applied to Land Resource Management

The objective was to investigate the usefulness of 3D geographic information technology (GIT) applied to land resource management and develop 3D soil-landscape models describing continuous changes of soil and landscape attributes.

Point-Set Topological Spatial Relations

Practical needs in the realm of Geographic Information Systems (GISs) have driven the efforts to investigate formal and sound methods to describe spatial relations. After an introduction of the basic

A Framework for Databasing 3D Synthetic Environment Data

The GIDB is overviews and the data structures of VPF+ and a prototyped 3D synthetic environment using VPF+.

Creating 3D oceanographic data visualizations for the web

The architecture of the system was designed to allow for incremental improvements in the presentation and in the underlying data quality, and an object oriented approach for the data access and use of the VRML97 EXTERNPROTO feature provided the framework for this architecture.
