The project commissioned by department of urban planning of local Trento Province with the goal to provide interactive access and in 3D -via the internet- to the geographical data of the Provincial Urban Plan (PUP) of Trento – Italy. From the technical point of view the project has brought to the development of a client-server architecture where a number of geo-browser 3D access in real-time the geographical data streamed by a central server. The architecture of the client application has been based on the WorldWind librares from Nasa which have been customized to cope with the specific requirements of the provincial authority. The server application has been completely developed by Graphitech with the goal of creating a very fast infrastructure capable of serving a large amount of clients at very high speed. For this the project has brought to the development of a set of classes capable to preprocess and compress the data available from the provincial plan according to an optimized data structure which is then sent via the network and then used by the client application. The main challenge of the project was set by the sheer size of the data set to be used by the project. In fact the urban plan covers the entire province territory, which is one of the widest in Italy, with a total surface of 6.200 square kilometers. Geographical information has been structured in more than 130 layers dealing with a number of different themes such as: · Data of environmental interest, such as protected areas, hydrography, natural parks, natural reserves, lakes, skiing areas, agricultural areas, glaciers etc. · Data related to infrastructure, such as power lines, streets, layers, airports, sewage etc. · Data of interest for urban planning, such as public infrastructure, administration borders, areas to be used for dwelling, industrial areas etc. The result is a system capable to show interactively a variety of themes over the entire provincial authority. The application is currently used as a planning tool by the staff of provincial.
