Metodology to develop a 3D-GIS heritage city model to support the monitoring of buildings' state of conservation: case study of Leiria downtown historical centre. 2380-2387. Abstract from 10th Euro-American Congress on Construction Pathology, Rehabilitation Technology and Heritage Management, Gijón, Spain.One of the huge challenges faced by the scientific community is related with the identification of solutions that allow the preservation of the tangible and intangible heritage historical city centres. Another issue is related with the management of architectural heritage information which faces significant challenges since architectural objects require an integrated representation of various types of information in order to develop appropriate conservation strategies. In the present paper, the author present results of the application of a 3D model developed for the Historic Centre of Leiria City (HCL) in Portugal, to contribute both to the conservation of the heritage buildings and to the dissemination of tangibe and intangible heritage of the historical city centre. The methodology applied included the integration of a 3D BIM model in a 3D-GIS environment to obtain an interactive system for the management, integration and presentation of historical urban geoinformation. For more than 0.40 km2 of the city, 3D GIS building geometry and thematic information have been processed. The model was enhanced with the application of textures and patterns and also with information about the non-structural pathologies associated to each building to support the municipality decisions related with the conservation of the historical city centre.8554229eng3D-GISShape GrammarState of ConservationThree-Dimensional ModellingMechanics of MaterialsBuilding and ConstructionGeography, Planning and DevelopmentCultural StudiesUrban Studiesconference objecthttps://www.scopus.com/pages/publications/85202642884
