Features edit
They was designed to carry out hydro-oceanographic surveys at high sea and in harbours and shallow waters, in order to guarantee the production and updating of nautical charts.
Main activities:
[3]
- sounding
- minimum depth
- topography of shorelines and port facilities
- seabed features
- collection of nautical and geographical data for the updating of nautical documentation
- detection of sunken vessels or dangerous underwater obstacles
The collected data are then processed by means of dedicated software programs and then used to produce:
- paper and electronic nautical charts for the safety of navigation
- Additional Military Layers
- nautical, scientific and technical documentation for mariners
- oceanographic databases for scientific purposes
Characteristics edit
