ABSTRACT
ABSTRACT: The use of 3D data is increasing as a wide range of traditional Gis applications and a number of novel ones are starting to exploit the potential of 3D data. The fact that CityGML has been recently adopted as OGC standard reflects this growing interest and, at the same time, adds further momentum. The use of CityGML data in operational applications requires a visualization tool with well defined characteristics. Starting from the analysis of the existing tools for CityGML visualization and of the characteristics required by the use of this model in a range of applications we decided to develop a new tool that we baptized Cityvu. Cityvu has been developed using state of the art software engineering methods and the results are very satisfactory as it fulfills all requirements and its performances are better than expected. Cityvu can visualize other 3D data formats in addition to CityGML and is now being used to develop an application to support public participation in planning decisions at the local level.
