The BathyCopter is a UAV-based LiDAR surveying system for bathymetric applications, ideally suited for generating profiles of shorelines and inland waterbodies. The robust and reliable platform design of RIEGL‘s remotely piloted RiCOPTER now integrates the RIEGL BDF-1, a compact and lightweight bathymetric depth finder comprising a tilt compensator, an IMU/GNSS unit with antenna, a control unit, and up to two external digital cameras. The RIEGL BDF-1 can optionally be supplemented with a miniVUX-1UAV LiDAR sensor. UAV-Based Surveying System for Hydrographic Applications Typical Applications • Generation of profiles of shorelines and inland water bodies (rivers, lakes, channels) • Repeated survey of water reservoirs • Canal surveying • Landscaping • Surveys for planning and hydraulic engineering work Scan this QR code to watch the BathyCopter video. www.riegl.com www.r

BathyCopter Measuring Principle tilt compensation Flight Direction constant angle flight path profile view The drawings above illustrate the measurement principle of the BDF-1 when operated from a UAV: The UAV performs a meanderlike flight path over an inland water body (river, channel, or lake) while the BDF-1 is measuring downward. In case the optional tilt compensator is used, the measuring angle is user-defined and stabilized. Profiles of the water surface (blue dots), ground (green dots) as well as the surrounding landscape (red dots) are generated this way. The multi-target capability of...
