Aerial Photogrammetry by drone in archaeological sites with large structures. Methodological approach and practical application in the medieval castles of Campo de Montiel

Abstract

<p>By writing this article we aim to illustrate the interesting combination of two existing techniques, accessible both for research groups and for professionals who want to study archaeological heritage: photogrammetry and aerial photography using a drone. We have applied these techniques to archaeological sites with standing structures, such as medieval castles in “Campo de Montiel” (Ciudad Real). Based on our expertise and experience, we have developed methodology for surface archaeological research, excavation and wall stratigraphy, thus identifying positive and negative aspects of this ethodology. The results obtained are truly positive, as we generated high-quality images offering news opportunities to investigate and show results, saving a considerable amount of time and money compared to traditional methods for graphical documentation.</p>
