Abstract

Tombolo is a narrow belt connecting the mainland with an island lying near the shore formed as a result of sand and gravel being deposited by sea currents, which is most often created as a result of natural phenomena. However, it can also be caused by human activity, as is the case with the Sopot pier - a town located in the southern part of the Baltic Sea. As a result, the seabed constantly rises and the shoreline moves towards the sea. This paper deals with metrological aspects of the undertaken tombolo effect investigation, namely accuracy analysis of the measurement results. Aforementioned analysis concerns two methods used for creating a 3D beach model: firstly using images from unmanned aerial vehicles (UAV) and secondly, based on geodetic laser scanning (TLS – Trimble Laser Scanner).
