Abstract

A marine airborne laser scanning (ALS) survey was performed on 10.05.2018 in the Gulf of Finland. An inverse distance weighted interpolation was employed to reconstruct the raw instantaneous sea surface heights as 1×1 m resolution grids, representing the high-frequency component. Alternatively, a 2D moving average low-pass filter was employed to determine the low-frequency component.
