4D Reconstruction and Visualisation of Krakow Fortress

The specific aim of the European project named "Cultural Heritage Through Time" (CHT2) and reported in this paper is to fully integrate the fourth dimension (4D) into Cultural Heritage studies for analysing structures and landscapes over time. Krakow – the Fortress City (Poland) is the one of four case studies of the CHT2, which are used for the time varying reconstruction, analysis, visualization, and preservation. The goal of the project is produce time-varying 3D products, from landscape to architectural scales, to envisage and analyse lost scenarios or visualize changes due to anthropogenic activities or intervention, pollution, wars, earthquakes, or other natural hazards. The results of the case studies will be the basis for web publication.
