The need for 3D geospatial data and the three-dimensional modelling of urban environments has steadily increased in the last decade as GIS applications improve their 2.5D and 3D spatial representation capabilities. This work presents the sequence of tasks performed for the construction of a virtual 3D model of the Faculty of Sciences of the University of Lisbon (FCUL) giving also some perspectives for future work based on the current needs of using such a platform, with emphasis on issues related to emergency building plans. Two main phases comprise this work: the definition of a methodology for modelling the exterior of buildings, aiming the development of a three-dimensional virtual photorealistic model of the Faculty, and the definition of a set of procedures for modelling their interior, for a visual and interactive exploration enriching the digital 3D environments. These two phases occurred at different periods of time, due to the nature of the needs for each one, and consequently, the technology used was different in each one as well as the procedures. Migrating from CAD technology to GIS technology, described on this paper, was one of the most time-consuming tasks in the process, but necessary for the final product. The final 3D model (exterior and interior of buildings) produced is currently being tested for several applications where the need for 3D is a requirement, namely the evacuation of multi-storey buildings in emergency situations.
