Satellite Derived Bathymetry

Satellite derived bathymetry (SDB) is a relatively new technique in hydrography that allows to create nautical charts and bathymetric maps of shallow waters and coastal regions. The biggest advantage is to cover a big area against relatively low investment in time and resources.

Satellite Derived Bathymetry Migration

Much has been said about Satellite Derived Bathymetry (SDB), but with the exception of SHOM, which led to the introduction of a number of SDB charts into the French chart series, next to nothing has been implemented within th... (read more)

Effective Surveying Tool for Shallow-water Zones

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)

Updating Landsat Satellite-derived Bathymetry Procedure

The General Bathymetric Chart of the Oceans (GEBCO) is an international body of experts that develops bathymetric datasets and products that are made available for public use. Among these products is the International Hydrogr... (read more)

Multi-sensor Coastal Mapping

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)

Improving Satellite-derived Bathymetry

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)

Satellite-derived Bathymetry

A study was conducted to evaluate the use of a satellite-derived bathymetry (SDB) procedure to map shallow-water bathymetry in a GIS environment, and to identify areas that require a new hydrographic survey. Publically availa... (read more)

Trends in Hydrography

It’s often a cliché to say that everything offshore has changed since the introduction of GPS, but I really think it’s true, almost everything has changed since back then in the 1980s. The other obvious tra... (read more)

Bathymetry From Space

Global grids of synthetic bathymetry make it a simple matter to portray generalised ocean depths in all parts of the world, except the central Arctic Ocean. Derived from measurements of satellite height above the sea surface,... (read more)

First NOAA Chart Adequacy Workshop

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)

Imagery-derived Bathymetry and Seabed Classification Validated

Proteus FZC, EOMAP and DigitalGlobe have formed a partnership to bring satellite-derived bathymetry and seabed classification to the hydrographic community. A pilot conducted by UKHO in the Mediterranean confirms that the sat... (read more)
