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.
Alseamar, a producer of glider UUVs, has been able to produce highly accurate data plots of current profiles from large swathes of the water column. A combination of tailor-made algorithms, underwater...
As the informed readership of Hydro International knows, the oceans sustain the planet. And, while there are many drivers of the changes to the Earth’s climate that now pose an existential threat to...
The detection of unexploded ordnance (UXO) in the sea is a demanding task. UXO survey data is acquired using a set of different sensors in different configurations and can span large areas. To make su...
Hydrospatial could be described as that portion of geospatial knowledge infrastructure that addresses the hydrosphere, and hydrospatial technologies support navigation, economic development, stability...
With the advances taking place in newly developed autonomous platforms, hydrography is accelerating its revolution towards a 4.0 industry. The deployment of uncrewed surface vessels means that human s...
Archaeologists have long been interested in shipwrecks. These sites can tell us about ancient transportation and trading routes, technological innovations and cultural exchanges over thousands of year...
With the ever-increasing and affordable availability of capacity and computing power to process and store data, the emergence of artificial intelligence (AI) in marine geomatics, ocean sciences and hy...
Hydrographic measurements are nowadays usually carried out using multibeam echosounders (MBES). The measurements obtained by each operational hydrographic vessel need to be regularly controlled on a w...
Hydrographers and data processors are expected to produce high-quality deliverables with a swift turnaround in this present age of data collection and technological refinement. However, the cost of pr...
Hydrographic offices (HOs) today exist in a world of accelerating technological change that is influencing human behaviour and creating new needs for and ways of exploiting data to understand our worl...
