This paper introduces a 3D environmental urban information system which is to help urban designers and developers to analysing and evaluating the environmental impacts of their urban projects. Where urban data is acquired from 3D urban models and environmental data is often coming from simulation software. For realizing environmental impacts analysis, the environmental urban information must be...

The needs for 3D city models are growing rapidly and the applications of those models on computer graphics and virtual reality are appearing in a variety of fields in recent years. In parallel, the speed of the internet communication is being greatly improved by the fast and wide spread of broadband infrastructure. Today, those web3D applications are waited eagerly that make possible interactiv...

According to the exponential growth of services available on large distributed networks, transport customers require relevant, interactive and instantaneous information during their travels. Thus, we designed and implemented a multi-agent information system using a special kind of software agents: the Mobile Agents. This work belongs to the national French project VIATIC.MOBILITE from the indus...
