Hydrographic Surveying, may also be known as Hydrography, is the science of measurement and description of seabed features which affect maritime navigation, marine construction, dredging, oil exploration and drilling, pipeline damage assessment and related disciplines.

Hydrographic Surveying is an essential activity to an island nation such as Australia. It underpins maritime trade and is essential to support coastal infrastructure, resource exploration and export, environmental awareness and coastal zone management.

“The prosperity of an island nation depends greatly on the extent to which it achieves excellence in hydrography.”
