Abstract
Brussels UrbIS from 2D to 3D

Established in 1987, in the context of the creation of the Brussels-Capital Region, the BRIC (Brussels Regional Informatics Centre) has been assigned the mission by the government to organize, promote and spread the use of information and communication technologies (ICT) among regional and local authorities, administrations and agencies as well as educational institutions, hospitals, emergency services, private companies, citizens… In this context, digital mapping became a core business for the BRIC. The objective of the UrbIS (Urban Information System) project was to develop a large scale reference digital map of the Brussels Region to respond efficiently to the numerous challenges facing the Region: town planning, architecture, mobility, security, utilities, environment management, archeology, taxation, statistical analysis… Given that users expect more and more data updated nearly in real-time, the BRIC set up a map production environment to maintain the UrbIS products. This environment is based on different elements among which Oracle spatial technology plays a crucial role in ensuring that the data are preserved. The day to day work on the data is done with Bentley Systems and FME software. This production environment enabled to speed up dramatically the frequency and the quality of the process steps. ESRI, Geonetwork and Geoserver solutions are also used to publish metadata and data on the web. The main part of the presentation will be focused on the production environment and its evolution to take into account the third dimension. For the latest extension of the UrbIS project, the BRIC decided to publish a tender in 2012 to acquire 3D data. Among the 3D deliverables, LiDAR data (>20 pts/m²) were used to create a new DTM and DSM and especially to build a LOD2 3D city model of the entire Brussels Region based on the CityGML specification, the development of which will be described in this session.
