“Cultural Heritage Through Time” (CHT2) is a European project whose scope is to develop time-varying 3D products, from landscape to architectural scale, to envisage and analyse lost scenarios or visualize changes due to anthropic activities or intervention, pollution, wars, earthquakes or other natural hazards.

The main aim of the CHT2 project is to merge heterogeneous information and expertise to deliver enhanced four-dimensional (4D) digital products of heritage sites. CHT2 is working on the full integration of the temporal dimension, its management and visualization, for studying and analysing Cultural Heritage structures and landscapes through time.

The CHT2 project has been made possible tanks to a co-funding from the Italian, British, Spanish and Polish research authorities in the framework of the “Joint Programming Initiative in Cultural Heritage” JPI-CH (http://www.jpi-culturalheritage.eu).

The actual JPI-CH action that supports the CHT2 project is Heritage Plus – an ERA-Net Plus project itself referring to the FP7 – whose implementation consisted in involving several European groups with innovative proposals developing current issues of cultural heritage, with a joint-call launched on March 2014 (http://www.jpi-culturalheritage.eu/joint-activities/joint-call/).

CHT2 resulted one of the 16 project selected for funding in that call (http://www.jpi-culturalheritage.eu/wp-content/uploads/CHT2.pdf).
