Once the vessel docks, the data is transferred to the Processing module. This stage is where the science of hydrography truly happens.
HYPACK is a specialized Windows-based software platform designed for hydrographic surveying, dredge control, and volume calculation. Originally developed in the 1980s by Coastal Oceanographics (now part of Xylem, Inc.), the software has evolved from a simple data logger into a fully integrated marine GIS (Geographic Information System). hypack
Maritime projects—from port maintenance to subsea cable laying—depend on precise knowledge of underwater topography. Traditional methods were time-consuming and error-prone. HYPACK addresses these challenges by offering a real-time, computer-based system that integrates data from sonars, GPS/GNSS receivers, motion sensors, and other peripherals. Since its inception in the 1980s, HYPACK has evolved from a simple data logger into a modular, powerful suite capable of handling complex marine workflows. Once the vessel docks, the data is transferred
A newer product line (2022+) allows users to process data from various water quality sensors and ADCPs directly within the HYPACK environment. Xylem Water Solutions Originally developed in the 1980s by Coastal Oceanographics
). It details a project in Boston, MA, where an autonomous vessel was used to conduct multibeam surveys. The post highlights how automation significantly reduced survey turnaround time by streamlining data acquisition.

This is the heart of the system. The Survey module is used for real-time data acquisition. A hydrographer uses this interface to see the vessel’s position over a basemap, monitor depth soundings, and ensure that data density meets project specifications.
