After having been mapping geological features at Río Tinto, the drone of the Group of Atmospheric Science (GAS) has been working at the archaeological site of Cástulo, completing the tasks scheduled for the Spain campaign. On this occasion, the imaging of the area is intended to support archaeological studies, showing the versatility of Unmanned Aerial Vehicles (UAVs) for their application to a wide range of investigations.
Cástulo is an ancient human settlement dated from 3,000 years B:C., located by the river Guadalimar, at some five kilometres from the town of Linares, in the South of Spain. It flourished as an important urban nucleus linked to mining, being inhabited successively by Iberians and Romans, cultures whose traces can be found in the site (buildings, infrastructures, tools etcetera).
Nevertheless, the excavations developed so far are fragmentary and partial, so the configuration of the city, which was highly populated and hence extensive, is still quite unknown. It is thought that Cástulo counted on a Roman amphitheater and a theater, whose allocation has not been accurately determined yet.
The imaging study to be performed by GAS is aimed to provide first very high-resolution terrain maps of the entire area which will further be used to identify features on the terrain that could provide clues about where these facilities could be placed in order to plan future excavation campaigns. All the known area has been mapped at high resolution, as well as its surroundings, since the perimeter of the old city is not well-defined, and new data of its extension and buildings can be found from the correspondent analysis.
