CHIMERA: A BIM+GIS SYSTEM FOR CULTURAL HERITAGE

Abstract. In the last years, many researches are conducted on systems for Cultural Heritage, trying to adapt BIM systems to CH needs; furthermore, the interest around the integration of BIM systems and GIS systems spreads. Chimera, presented in this paper, is the final product of about 8 years of research on this broad topic and has been specifically conceived for the realm of CH. It joins the small group of ready-to work information systems that allow the concurrently use of different integrated data, as 3D models, point clouds but also 2D maps or images. It also presents different functionalities that allow to work at a multiscale approach, including switching from a “single object level”, to the a “building level” with a BIM-style system, to a more extensive “environmental level” GIS-style information system and giving the possibility to manage transversal information and to analyse each case from different point of views and at different level of detail.
