Discussing and comparing software has often been tricky in Hydro International as it is difficult to put the packages together and see clear differences. In this overview of hydrographic processing software, we will highlight trends and movements as indicated by  t... (read more)

Ports require access to a wide range of data and information to function safely and efficiently. Some of that data is acquired from external stakeholders but most is generated internally within the port. It is very often managed and held within a single software application,... (read more)

A recent article provides an overview of satellite-derived bathymetry methods and how data can be integrated into survey campaigns, and showcases three use cases. Bathymetric data in shallow-water zones is of increasing impor... (read more)

Bathymetry is traditionally acquired using singlebeam or multibeam echosounders. This method produces accurate depth measurements along transects but is constrained by operating cost and an inability to survey in very shallow... (read more)

The Naval Oceanographic Office (NAVOCEANO) utilises a diverse suite of survey assets to collect high-resolution oceanographic and hydrographic data in shallow-water areas all over the globe. These assets maintain a high opera... (read more)

SHOM contributes routinely to the preparedness against coastal risks along French coastlines. For this purpose, regional to coastal digital elevation models are built for implementation in forecast systems against rapid flood... (read more)

Hydrographic surveys in very shallow waters can have several applications such as nautical chart updating, performing environmental monitoring and characterisation, determination of dredged volumes, establishing navigational... (read more)

There are settings where an unmanned survey represents more than a safe, cost-effective alternative; it may be the only option. Capitol Lake in Olympia, WA, USA, is such a location. In this article, we report on a recent surv... (read more)

Fugro recently tested a multi-sensor approach to balance growing data needs with limited agency budgets. Coastal mapping programmes are quickly becoming a priority for government agencies across the globe. The desire to bette... (read more)

Quality control of survey data is an integral part of any hydrographic survey or inspection operation, but the focus is too often concentrated on the wrong sensors, the carrying out of unnecessary comparisons and ultimately b... (read more)

Seaports, waterways and climate are inextricably linked. Weather anomalies change bottom contours and destroy aids to navigation, compromising safety. In the past decade maritime applications, maturing marine technologies and... (read more)

Currently only ten to fifteen percent of the ocean floor has been mapped at resolutions of 100-metre pixel size or better and the vast majority of this mapped area is within territorial waters. One way to significantly increa... (read more)
