Multi-sensor Integration of Hydroacoustic and Optoelectronic Data Acquired from UAV and USV Vehicles on the Inland Waterbody

: Hydrographic and photogrammetric measurements in the coastal zone are performed using hydroacoustic and optoele ctronic methods, in particular with the use of Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicles (USV). It should be remembered that each of the devices registers data in a different spatial reference system. Therefore, before starting the analysis of geospatial data, e
