Geographical information (GI) or geoinformation describes phenomena associated directly or indirectly with a location (coordinates systems, address systems…) with respect to the Earth’s surface. Such phenomena can be either spatially discrete (represented by geometric primitives like points, lines, regions, etc.) such as a municipality, a road axis, etc. or spatially continuous (represented by interpolation on an image grid for example) such as terrain’s elevation, pollution diffusion, etc. GI is created by manipulating geographic data (or geospatial data) in a computerized system. Geospatial data can be acquired by different means: topographic survey, remote sensing, aerial photographs, GPS, laserscan, and all other types of sensors or survey techniques. Traditionally, these data are the core component of Geographic Information Systems (GIS), which is the term commonly used to refer to the software packages that allow to capture, store, check, integrate, manipulate, analyze and display them.

3D geodata are more and more available as well as realtime visualization possibilities with free three-dimensional viewers such as Google Earth. This implies a growing demand of 3D city models, which are 3D representations at the scale of the city. Despite their intended wide range of applications, such models cannot be used for many urban tasks as they cannot represent the urban information associated with these tasks. On the contrary, ontologies have proven their capacity and usability in the representation of information and knowledge of various domains. Besides, interoperability is a crucial problem for urban information systems. Transferring information between different systems or models requires the ability to set up correspondences between concepts from one system to concepts in the other one. The use of ontologies can greatly facilitate this mechanism of concept matching. In this paper we will present, on the basis of case studies, how ontologies can overstep the semantic limitation of 3D city models and how ontology-based approaches can be used to interconnect urban models in order to improve their interoperability.

Virtual Leodium is a project aiming to scan and digitize a master piece of the collection of the University of Liège, the historical model of the city of Liège around 1730 realised by Gustave Ruhl. The two main originalities of the approach are to use a projected-fringes scanning technique and to generate a geo-database as a support for archaeological information. This interdisciplinary project gathers physicists, geomaticians, librarians, and archaeologists. [less ▲]

Although intensive works have been devoted to spatiotemporal modeling during the last two decades, there are only a few models dedicated to relationships between two (or more) moving objects. This paper proposes a classification framework of spatiotemporal relationship models based on the ways spatiotemporal histories are analyzed. First, we discuss model conditions of application. Then we propose a classification of spatiotemporal relationship models based on a pyramidal representation of the quantity of extracted information, i.e. the nature and the complexity of provided information, from spatiotemporal histories. This classification aims helping users to choose adequate models for their purposes. The proposed spatiotemporal histories analysis method could lead to the development of new spatiotemporal relationship models. [less ▲]
