Analysis of Transformation Methods of Hydroacoustic and Optoelectronic Data Based on the Tombolo Measurement Campaign in Sopot

Measurements in the coastal zone are carried out using various methods, including Global Navigation Satellite Systems (GNSS), hydroacoustic and optoelectronic methods. Therefore, it is necessary to develop coordinate transformation models that will enable conversion of data from land marine parts one system. The article presents selected issues related integration geodetic hydrographic data. aim this publication present methods their effects relate tombolo measurement campaign Sopot conducted 2018. Data obtained GNSS Real Time Kinematic (RTK) measurements, Terrestrial Laser Scanning (TLS), Unmanned Aerial Vehicle (UAV) Surface (USV) were transformed. On basis used, can be concluded adjustment calculus method best results for plane coordinates, while P.S. Dąbrowski et al. height coordinates. standard deviation difference modelled coordinates acquired by with respect reference amounted to: 0.022 m (Northing), 0.040 (Easting) 0.019 (height), respectively, allowed obtain following values: 0.009 0.005 0.359 (height). It assumed a combination these two seven-parameter would provide results. In future, new should developed based on synthesis existing
