ABSTRACT
This chapter presents the application of multispectral images of very large resolution, from different years, for the automatic detection of time changes of buildings' roofing materials and nonstructural anomalies using a hybrid methodology. This is an evolution of the method developed by Gonçalves, the development of a 3D-GIS model that incorporates a geodatabase to store the information related to the history and the pathologies of each building of the model. The 3D-GIS city model of the historical city centre of Leiria was enriched with a collection of pathological information. The final model enables an interactive system for the management, integration and presentation of historical urban geoinformation. The development of Web services for the model's contents could extend the ways in which the city model can be accessed by the municipality technicians and other partners contributing to the preservation and promotion of the built capital, heritage identity and memory.
