International audienceDue to the advances in computer graphics and improved network speed it is now possible to navigate in3D virtual world in real time. Until now, technologies employed require to install standalone application orplugins on navigators. The arrival of HTML 5 brings news solutions to visualize 3D data in a browser withWebGL. Several globe projects have proven that such technologies can be employed. Unfortunately, demonstrationsare often based on proprietary formats to exchange or to store data. In this work, we propose touse CityGML: a standard provided by the Open Geospatial Consortium. CityGML files are imported in ourEnvironment Editor.

Due to the advances in computer graphics and improved network speed it is now possible to navigate in 3D virtual world in real time.

Several globe projects have proven that such technologies can be employed. Unfortunately, demonstrations are often based on proprietary formats to exchange or to store data. In this work, we propose to use CityGML: a standard provided by the Open Geospatial Consortium. CityGML files are imported in our Environment Editor. With several tools that we present in this paper, data are processed and stored. A client server application is also presented to permit the visualization of geometry and semantic in a navigator.
