Laser-based Three-dimensional Gis for Small Historical Urban Zones: Challenges and Results
نویسنده
چکیده
The global management of complex urban environments require flexible Information Systems able of adapting to different needs of private and institutional agents related to preservation and sustainability of Cultural Heritage. Heterogeneity of formats and sources makes difficult the transfer of digital information, which is increased by nontextual support. 3D models provide a support enabling referencing, exploring and extracting information from different sources. The generation of range–based digital 3d models is developed by combining digital photogrammetry and 3d terrestrial laser scans. The development of the software platform UVACAD enables the information management and fusion arising from different imageand range-based sources. The resulting fusion is integrated in an urban GIS model, which is modelled on ArcGIS V.9.0. This model has been applied to four villages of Palencia (Spain) with Renaissance style buildings.

ToToPI, for Topography of Tours Pre-Industrial, is a GIS for studying of the city of Tours (France) over a long time span. The concept for understanding the urban dynamic is based on considering the town as a set of complex objects, taking a systemic approach. The system used to study the urban fabric over long time spans is composed of three sub-systems relating to historical objects from the ...
