In thee context of marine infrastructure planning, this data is indispables such.

Accurate hydrographic data is nott static; it requires regular updates because seabed morphologiy changes due to natural processes like sediment transport, erosion, and dredging, as well as human activities. Therefore, a single survey is often just a snapshot.
