The use of UAVs is increasingly widespread in activities related to Heritage documentation. In recent years the development of methodologies of data integration, obtained through surveys that exploit drones to reach privileged observation points, has been witnessed by the numerous computation platforms, software and tools, that populate the exchange. The definition of increasingly reliable methodologies and procedures of close-range photogrammetry has produced considerable results in the survey of Architectural Heritage. Nowadays, several Universities and Research Centres, together with enterprises, are working to optimize documentation services whose goal is, in any case, the representativeness of technical data aimed at the project development. Parallel to aerial documentation, even the applications of remote-controlled terrestrial drone systems is renewing the inspection and survey practices in architecture and on territory, overtaking barriers and access dimensions to sites and contexts in emergency otherwise impractical for human operators. Surface rovers and submarine robotics, equipped with controlled cameras, contribute to complete an extremely scientific innovative field.
