Abstract Archaeology is benefiting from fresh technological developments that are introducing new recording systems based mainly on 3D modelling. Innovative digital recordings are improving key aspects of archaeological practice, including accuracy and efficiency. This is the case of a novel procedure that uses Unmanned Aerial Vehicles (UAVs) for data acquisition and software such as Structure from Motion (SfM) to produce volumetric models from photographs. These photorealistic 3D models can be processed further using Building Information Modelling (BIM) to create plans, sections, digital elevation models, orthophotographs and other types of images useful for analysis and publication. The study of the architectural features of the megalithic necropolis of Panoria (Granada, Spain) has benefited from these innovative technologies.
