Resilience in art cities: planning for emergencies

The RECIPE project aims at providing low cost 3D models of cultural assets using as source of information photos taken by tourists through non-professional devices (e.g. smartphones, Tablets) integrated with Earth Observation products in order to preserve cultural heritage from natural or anthropic disasters. The low cost of the service, which is one of the main goals of RECIPE, permits to extend the affordability of 3D models also to minor cultural assets. The service targets several user communities such as: public administrations both central and local; municipalities; engineering and/or architecture offices; conservation institutes; tourist operators; surveys, mapping and photogrammetry firms; cultural asset managers; archaeological site managers; research centres and universities; and insurances. The service makes use of EO, GNSS and satellite communications data. Images taken through EO satellite offer the compulsory real proportion of the building to constrain the 3D model reconstruction without need of costly and lengthy survey of the site. GNSS that allows the geo-localization of the pictures taken by the tourists increases the quality and speeds up the process to render the 3D Models. Finally, satellite communications are used o integrate terrestrial communication means to guarantee Hot-Spots where the tourists can promptly upload their pictures.
