By harnessing capabilities of advanced satellite technology and ever-evolving data analysis, satellite-based mapping (including satellite-derived bathymetry, SDB) offers an efficient, extensible and cost-effective method for mapping water properties, underwater topography...

In the quest to unravel the mysteries beneath our planet’s water bodies, topobathymetric technologies emerge as a beacon of innovation. Among them, Lidar (light detection and ranging) and sonar sensors...

Unmanned surface vehicles (USVs) are increasingly being used for the mapping and management of shallow-water environments such as lagoons, rivers and estuaries, due to their economic and ecological benefits. The...

The Denmark Depth Model (DDM) is a digital bathymetric model covering Denmark’s exclusive economic zone (EEZ). It was developed based on hundreds of bathymetric survey datasets and historical sources and...

Since the 1970s, remote sensing has increasingly been used to conduct underwater surveys. Several methodologies are employed in hydrographic surveying, from direct techniques such as probing rods to more sophisticated...

Uncrewed 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 this data...

The national land agency in Jamaica has integrated satellite-based hydrography to benefit from time efficiencies, cost savings and improved safety as part of its hydrographic programme in support of the...

With shallow-water surveys not required to be performed with the accuracy and precision of industrial projects, surveying devices with lower costs are being welcomed by hobbyists eager to determine water...

This article will immerse you in the deep water of bathymetry. It explains in detail what a bathymetric map is, what it shows, what methods we use to collect the...

FarSounder is the most recent company to join the International Hydrographic Organization’s Crowd-Sourced Bathymetry (CSB) initiative by becoming a “trusted node” with the NOAA. This project enables mariners to voluntarily...
