Drones, or Unmanned Aerial System (UAS) or Remotely Piloted Aircraft System (RPAS) carry the researchers' eyes and instruments into the air.
The UvA Dronelab, housed at the 4DRL, is an ROC certified drone operating research unit that is specialized at drone-based remote sensing and all kinds of related airborne data and imagery/videography capturing.
Drones for Research
In digital humanities, the use of drones is a fast developing innovative technology. Using various cameras and sensors, drones can help to capture landcapes and identify sites and architecture in 2D and 3D.
Drones have become essential to carry out modern archaeological fieldwork (both surveys and excavations). However, datasets collected using drones, whether aerial imagery/videography, high quality 3D models or thermal orthophotos can benefit any research area studying architecture, infrastructure or landscape.
Since drones are generally cost-effective, operationally flexible and easy to use, they enable the creation of new and valuable datasets, allowing research questions that have not been possible before.
What can they do for us?
Drones fill a niche between terrestrial scanning and geophysical remote sensing on the one hand, and airborne reconnaissance using planes, as well as spaceborne reconnaissance using satellites on the other.
Being able to fly at low altitudes, move unobstructed over uneven surfaces, hover in mid-air and cross water, they provide opportunities to collect unique and valuable data at very high resolutions. The ongoing miniaturization of sensor types such as thermal cameras, georadar and LiDAR, opens up a range of possibilities for advanced data collection techniques. Drones in combination with photogrammetrical software (Image Based Modeling, or IBM) turn into flying 3D scanners.
UvA = Airborne!
ROC = RPAS operator Certificate
In short, the ROC authorizes the UvA Dronelab for operating >4kg drones, flying at an extended altitude and distance from the pilot, enter restricted airspace, and requesting clearance for entering urban areas, military areas and (parts of) airport controlled areas.
ARCfieldLAB is an E-RIHS-funded project aimed at improving the quality of archaeological fieldwork and research in the Netherlands. Achieved by collecting information on the most important technological and methodological innovations of the last ten years in the field of archaeological remote sensing.
Medieval site of ‘t Huijs ten Bosch, Weesp
The drone remote sensing operations investigated the Medieval castle ‘t Huijs ten Bosch in Weesp. The project entails an investigation into both the application and comparative value of innovative sensor techniques for prospection purposes as well as nature, extent, and state of preservation of the site itself.
DRONE-BASED REMOTE SENSING AT HALOS, GREECE
2022 - 2023
The archaeological landscape of ancient Halos in central Greece provides a good testing ground for the possibilities that drone-based prospection has to offer. Using thermography and multispectral imaging, we contribute to the research of the site being done by the University of Amsterdam, in collaboration with colleagues of the Greek Archaeological Service (the Ephorate of Volos).
In a short fieldwork operation at Siegerswoude (NL) in collaboration with the Rijksdienst voor Cultureel Erfgoed (RCE), high quality data was collected from an agricultural field featuring an archaeological anomaly. The slightly sunken elongated feature was interpreted as a ditch dug as part of a Medieval peat extraction settlement under construction.
During one week of fieldwork at the famous site of Troy in Turkey in the context of the Archaeology of Archaeology at Troy Project, an extensive 2D, 3D and thermal mapping of the site were carried out. The main purpose was to create an accurate model of parts of the site for the above mentioned project, as well as to experiment with drone thermography.
The drone remote sensing operations were part of an ongoing ACASA investigation. Optical and thermal sensors were used, accompanied by a GPR survey, which together revealed features of a 7th-6th century BC Etruscan townscape.
