This summer, Sjótækni's employees were involved in multi-beam measurements on Ölfusá by Selfoss with the company's remote-controlled measuring boat. Mapping was done on the bottom of the river so that it was possible to better understand what the bottom looked like and what the depth was. The boat proved to be good at measurements in the river despite a high current and a lot of turbidity in the water and it was possible to map the bottom of the river quite well.
