Abstract
Abstract. Drones are becoming essential in the field of heritage surveying, especially for large-scale archaeological site. The precision offered by the new survey tools (UAVs, sensors, processing software, etc.) should make it possible to obtain enough information to complete the plan of a site on an urban scale.This paper shows the use of two types of sensors embedded simultaneously on a UAV with the aim of highlighting information that is often difficult to detect on the ground. By crossing RGB and thermal data, certain built-up limits seem to appear. Thanks to this new information, hypotheses of the urban structure are proposed. In other words, the aim is to bring out circulation hypotheses within a large complex archaeological site. Unlike the field of architectural survey where thermography is widely used, for example, to identify certain building pathologies, in archeology this technique does not seem to be part of the traditional survey pipeline and even less on large-scale sites. The possibility of using a third type of sensor is also sketched. The aerial-GPR would in fact make it possible to confirm the presence of a buried structure without having to go through systematic excavation and could provide a three-dimensional image of the ruins.
Highlights
Nowadays, there are many tools from several disciplinary fields (Jockey, 2013) for carrying out surveys of built heritage
It is a tool suitable for surveying large-scale structures. These technological evolutions in the field of heritage surveying stimulate the ambition of an accuracy that can reach the scale of 1/1 and reproduce exactly the reality (Vergnieux, 2009), at a time corresponding to the acquisition, in a virtual space
It is important to specify that the term ‘survey’ implies a sequence of operations which starts with the acquisition of data and ends with the representation of the object studied (De Luca, 2006; PierrotDeseilligny, De Luca and Remondino, 2011)
Summary
There are many tools from several disciplinary fields (Jockey, 2013) (engineering, computer science, architecture, archaeology, etc.) for carrying out surveys of built heritage. Each of these tools provides its own set of data and offers the possibility to accurate the knowledge of surveyed building. It is a tool suitable for surveying large-scale structures. These technological evolutions in the field of heritage surveying stimulate the ambition of an accuracy that can reach the scale of 1/1 and reproduce exactly the reality (Vergnieux, 2009), at a time corresponding to the acquisition, in a virtual space. It is important to specify that the term ‘survey’ implies a sequence of operations which starts with the acquisition of data and ends with the representation of the object studied (De Luca, 2006; PierrotDeseilligny, De Luca and Remondino, 2011)
