Recently, GeoConnexion published an article about a pilot project, where UAV-mounted LiDAR was used to discover hidden traces of prehistoric settlements near Vienna, Austria.
In the course of the project “Archaeology at the Danube – Bisamberg Pilot Study” the Austrian Archaeological Institute (ÖAI) of the Austrian Academy of Sciences (ÖAW) conducted a survey of the archaeological ground monuments (including a prehistoric ramport) on the Bisamberg using modern non-invasive aerial and ground prospection methods.
For LiDAR data acquisition a RIEGL miniVUX-SYS (with RIEGL miniVUX-3UAV LiDAR sensor and APX-20 UAV INS/GNSS) mounted on a DJI M600 UAV platform was used.
Based on the sensor’s high-penetration capability, the pure digital elevation model (DEM) of the entrenchment and the surrounding area made a large amount of archeological information visible, that is actually hidden under dense vegetation.

About the RIEGL miniVUX-3UAV LiDAR Sensor:
The RIEGL miniVUX-3UAV is an extremely lightweight airborne laser scanner, designed specifically for integration with UAS/UAV/RPAS. The sensor offers a selectable 100 kHz, 200 kHz, and 300 kHz laser pulse repetition rate (PRR). With 300 kHz PRR, it provides up to 100,000 measurements per second at 120° FoV and thus a dense point pattern on the ground for UAV-based applications that require the acquisition of small objects. With up to 5 target echoes per laser shot, the scanner is able to penetrate even dense vegetation and delivers excellent data for computing detailed terrain models.
