The main goal of this training course was to build a new geographic database centred around public space features. Private space is well identified since cadastral parcels have been described in the previous database. Firstly, the context of this training course is presented, emphasising on links between conveniors in the GIS equipment project. Organisations of new and ancient systems are highlighted, which allow us to overview improvements and minimum goals to reach necessarily. The second part explains how the theoretical design of public space database was developed, thanks to the object-oriented HBDS method. Public highways have been featured by two ways: with polygons or polylines. Polygons which divide public highways according to streets extents, will enable to get some information about owners of this public space (State, Department, Commune, COMADI). Linear components of public highways and bridges are the fundamental parts of road network. Thus, labels can be displayed along these features so as to match cartographic rules. Moreover thematic maps can be built with these linear features. Point features layer representing addresses permits the creation of a geocoding file in order to pinpoint data that have only mailing addresses. The third part describes how the technicians and me have created data relative to public highways and public space. We have shared public highways to obtain real extents of streets. Then, we have built the road network composed of streets and bridges. At the same time, we put semantic data into tables so as to identify geometric features. The outcome of this work has been to create a geocoding files with addresses. Finally, the conclusion of this report sums up some important points which will be necessary to a good deployment of this GIS. One of them is human factor, because the other components of this GIS are already available (data, software and hardware). The training of technicians is the remaining phase before having an efficient system. Some problems have occurred during the first month of the use of software, but they were actually solved. Nevertheless, I emphasise on the ways to rapidly increase technical performances.
