Use of UAS for the conservation of historical buildings in case of emergencies

The task of conservation and management of cultural heritage is quite central in Italy, which lists a high number of beautiful architectures. A quick and precise survey may be requested in case of calamity. In the present paper, the most commonly used survey techniques are discussed, focusing on their applications for the conservation of the artistic heritage in case of emergency. Particular attention is given to Unmanned Aerial Systems (UAS) photogrammetry and its potentiality in obtaining good results in terms of speed, cheapness, precision and accuracy, assuring at the same time the safety of the operators in critical situations (e.g. natural disasters). A case study, realized at the Castle of Casalbagliano (Alessandria, Italy), is discussed. Different image block configurations and acquisition geometries (nadiral and oblique images) have been exploited, with the aim of defining useful guidelines for emergencies UAS survey of partially collapsed structures. An application to a significative case study is introduced

Gestione e pubblicazione di dati territoriali con tecnologie open: le esperienze maturate con piccoli e grandi enti del Veneto

In recent years, the use of Gegraphic Free and Open Source Software (GFOSS) by the Italian public administration is more diffused (CAD, 2013) even if the suspicion that proprietary software is more able to completely solve the problem of the management of a complex geoportal of a big municipality is still present. In this paper we present two examples of publication of geodata using GFOSS for two different town of Veneto Region (Italy): the SitVi 2.0, that is the webGIS of the Vicenza Municipality (~ 110’000 inhabitants) and the webGIS of the Legnago town (~ 25’000 inhabitants)
