Geographic information systems have a primary role to play for sustainable urban development, as tools for collecting and analyzing environmental properties of buildings and urban spaces, either as a support for communication and public participation in urban planning. To this end, GIS should take into account the third dimension and they should be able to interoperate with existing simulation ...

1. Introduction The choice of relevant data models and data structures is still an important issue in 3D GIS. In the 3D urban GIS context, boundary representation models are usually adopted with different levels of " topology " integration In this work, a new approach based on projective properties of spatial objects has been adopted. The theoretical framework behind this is the Dimensional Mod...

The changing trends in information technology have greatly influenced the role of GIS in spatial data management, analysis, processing and presentation. It has evolved from the conventional cartography and image processing to advanced 3D visualization and dynamic graphics tools. Due to this evolving nature of GIS, it has found wide applications in a number of diverse fields. Geophysical explora...

Commercially available scheduling tools such as Primavera and Microsoft Project fail to provide information pertaining to the spatial aspects of construction project. A methodology using geographical information systems (GIS) is developed to represent spatial aspects of the construction progress graphically by synchronizing it with construction schedule. The spatial aspects are depicted by 3D m...

This paper describes the combination of two technologies, augmented reality and GIS, to provide a new way to visualise viticulture GIS data using outdoor mobile computers. Viticulturists use GIS to assist with accurately understanding the parameters that affect their yields and quality of the grapes from different vineyards. The ability to view this data in the field digitally would be advantag...

While error propagation in GIS is a topic that has received a lot of attention, it has not been researched with 3D GIS data. We extend error propagation to 3D city models by using a Monte Carlo simulation on a use case of annual solar irradiation estimation of building rooftops for assessing the efficiency of installing solar panels. Besides investigating the extension of the theory of error pr...

Aimed at ancient architectures which own the characteristics of huge data quantity, fine-grained and high-precise, a 3D fine management and visualization method for ancient architectures based on the integration of 2D and 3D GIS is proposed. Firstly, after analysing various data types and characters of digital ancient architectures, main problems and key technologies existing in the 2D and 3D d...

Storage, processing and visualization of 3D geodata are an important subject in the GIS world even before the leading search engine introduced its globe viewer. Usage of standards of the Open Geospa-tial Consortium (OGC) open up new possibilities for combination and usage of 3D geodata. First practical experiences show promising results.

This paper presents GroupCollaborate2, a prototype Participatory GIS for the management of 3D community maps which support the shared design of public policies by offering a virtual representation of the territory and by enabling the crowdsourcing of heterogeneous types of contributions, including documents, 3D models and comments, within focus groups. The paper sketches user requirements and p...
