Depth data

Depth data consists of depth points obtained from full-coverage surveys or soundings along a predetermined line.

Depth data is primarily used for the production of nautical charts, fairway planning and maintenance. In data produced with full-coverage depth measurement methods (echo sweeping and multibeam surveys), the point density is < 2m. When using other measurement methods (for example sounding along a predetermined line), the point density is 10–40 metres.

Depth data is available on sea areas and the Vuoksi, Kymi and Päijänne watercourses. There is more detailed depth material in merchant shipping lanes and in small craft tracks. In other areas, the availability varies.
