Survey with UAV and DSLR: an integrated approach. The case study of St. Agatha church and Castrum Padi

This paper reports the results of a research project aimed at the survey, historical knowledge and archaeological understanding of the St. Agatha church in Povo (Trento), which was supposed to be built in XV-XVI century over the ruins of a castle that some sources refer from 1208 to 1375. An extensive use of digital photogrammetry with UAVs and DSLRs, alongside the topographic instruments like total station and GNSS receiver, provided a complete survey of the church and surroundings, and eventually brought to the discovery of borders and walls of the ancient castle.
