Modelling Higher Dimensional Data for GIS Using Generalised Maps

Real-world phenomena have traditionally been modelled in 2D/3D GIS. However, powerful insights can be gained by integrating additional non-spatial dimensions, such as time and scale. While this integration to form higher-dimensional objects is theoretically sound, its implementation is problematic since the data models used in GIS are not...

Generation of a National Virtual 3D City and Landscape Model for the Netherlands

This paper describes the generation of a national three-dimensional (3D) dataset representing the virtual and landscape model. The 3D model is produced automatically by fusing a two-dimensional (2D) national object-oriented database describing the physical landscape and the national high-resolution height model of the Netherlands. Semantic...

Manipulating higher dimensional spatial information

Real-world phenomena have traditionally been modelled in a GIS in two and three dimensions. However, powerful insights can be gained by the integration of additional non-spatial dimensions, such as time and scale, in a higher dimensional spatial model. While this theory is conceptually sound, there is a lack of understanding of its consequences...

Generation and Dissemination of a National Virtual 3D City and Landscape Model for the Netherlands

This paper describes the generation and dissemination of a national three-dimensional (3D) dataset representing the virtual and landscape model. The 3D model is produced automatically by fusing a two-dimensional (2D) national objectoriented database describing the physical landscape and the national high-resolution height model of the...

Repair and generalization of hand-made 3D building models

Many 3D GIS applications require 3D building models with different LoD (Level of Detail) that satisfy certain quality criteria. However, because of their complexity, most detailed 3D building models available are still produced manually, which results in inevitable geometric and topological errors. These errors hinder the downstream processing...

Integrating Scale and Space in 3D City Models

This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach. We conclude with work in progress and explain the benefits of our approach.

5D Modelling - applications and advantages

As explained in van Oosterom & Stoter (2012), the nD modeling approach allows us to include different aspects of geo-information in spatial modeling at a fundamental level, i.e. by treating these aspects as additional (geometric) dimensions. This paper explains how nD data models and data structures may solve the issues of redundancy and...

Een landsdekkende BGT, zonder gaten en overlap

Een van de uitdagingen van de Basisregistratie Grootschalige Topografie (BGT) is om de data afkomstig van de vele bronhouders samen te voegen tot één landsdekkende, topologisch correcte database. De regels in de BGT-catalogus zijn duidelijk en het combineren lijkt simpel. Maar de praktijk is weerbarstiger. In dit artikel leggen we uit waarom ...

Design and development of a 3D cadastral prototype based on the LADM and 3D topology

In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant...
