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)

The key objective of the NOAA Chart Adequacy Workshop was to demonstrate techniques to evaluate the suitability of nautical chart products using chart quality information and publicly-available information. The three-day work... (read more)

The visualisation of bathymetric data and associated uncertainty in electronic nautical charts (ENCs) is important when it comes to planning and monitoring a ship’s route safely. However, a study confirmed that the curr... (read more)

Fugro has 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)

There is definite appeal to the concept of crowdsourced bathymetric data. But from where I sit as a National Hydrographer and nautical chart producer, the issues around using crowdsourced data are complex. Data quality, data... (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)

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)

Synthetic Aperture Sonar (SAS) has been around for over a decade but its primary purpose has been in mine detection rather than hydrographic surveying. To use SAS effectively a stable survey platform is required such as an au... (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)
