These theme weeks take us to the very core of our industry. The nautical chart – the original driver of hydrography – is still going strong and, be it in paper form or ENC, is used on every ship. To create these, extensive bathymetric surveys are performed and additional data is collected on aids to navigation and topography. However, it is not only the nautical chart that requires bathymetric data: this is and will continue to be the backbone of hydrographic surveying employing echosounders, side-scan sonar and advanced positioning systems.
Unmanned vehicles, both surface and airborne, are increasingly being used for hydrographic surveying. While the technology of data acquisition using these platforms is generally known, the fusion of t...
Two Hungarian companies designed a three-step data collection workflow to overcome the challenges in this urban surveying project in Hungary, which included the use of UAVs and remote-controlled boats...
When looking to buy hydrographic processing software, it is important to establish the requirements in order to find the best software for the job at hand. The users’ technical skills, the type of d...
Artificial intelligence (AI) first came to light in the 1950s, when the ability of a machine to undertake an operation and adapt to changing conditions without human input was skirting the edges of sc...
Seafloor pipelines are a critical infrastructure for oil and gas transport. Timely inspection is required to verify their integrity and determine the need for maintenance, as failures in these pipes m...
In this edition of our Q&A series with leading experts from the hydrographic industry, Paul Seaton of Fugro shares his thoughts on a variety of topics, such as key market trends, technology drivers an...
Wreck search is a special application of hydrographic surveying. Countless sunken ships – or what’s left of them – have been discovered over the years, often by means of a combined survey with m...
While online data acquisition is of course of the utmost importance in hydrography, technological developments mean that modern surveyors also need to know about data science, machine learning and art...
Two uncrewed surface vessels (USVs), remotely controlled via satellite, conducted pioneering survey work on Lake Superior for the Canadian Hydrographic Service (CHS) in partnership with IIC Technologi...
The multibeam echosounder (MBES) is used for various purposes, and MBES systems have become the standard instrument for bathymetric determination. However, new developments mean that MBES systems are ...
