Satellite-Derived Bathymetry for Coastal Monitoring Solutions

Satellite-Derived Bathymetry for Coastal Monitoring Solutions

By EOMAP

Coastal zones represent some of the most densely populated regions of the world and are under increasing pressure from man-made activities. Coastal zones are highly dynamic (Syvitski et al. 2005) and are subject to change in the short term for example changes caused by extreme weather events and long term for example changes caused by erosion and currents. Offshore and coastal engineering activities can modify coastal landscapes significantly, and man-made disasters can have dramatic impacts on the coastal environment. All these changes create a high demand for spatial and environmental data to aid in coastal zone management.

A consistent spatial framework is necessary and challenging, especially because the continually shifting land–water interface poses significant logistical problems for mapping (Committee on National Needs for Coastal Mapping and Charting 2004). The extremely dynamic nature of coastal marine
environments makes it especially difficult to monitor. Important issues in coastal monitoring include water characterization, observations of water-quality trends over time, identification of emerging problems, and information for pollution prevention and emergency response (Siermann et al. 2014).

Satellite-Derived Bathymetry

The greatest demand is for up-to-date shallow bathymetric data (Committee on National Needs for Coastal Mapping and Charting 2004) to provide the fundamental geospatial framework which is essential for navigation, port and offshore construction, security, coastal zone management, fisheries management, coasta lrestoration, and tourism.

Vessel- and aircraft-based methods for coastal monitoring surveys can be cost and time consuming, depending on the level of detail required. For these reasons, extended areas of water worldwide are not mapped in detail, or existing data may be out of date, especially in dynamic environments. The demand for bathymetric data is therefore obvious and lack of this data causes risk to navigation and concerns to the offshore industry and beyond.

The value-added services provided by satellite images can increasingly contribute to fill geospatial data gaps and support continuous monitoring.

 

SDB Day 2018 – Satellite-Derived Bathymetry Technology and User Forum

The first international conference on Satellite-Derived Bathymetry (SDB Day 2018) is now open for registration to discuss key issues on capabilities, data integration and quality standards. The Satellite-Derived Bathymetry Technology and User Forum will be held on June 6 and 7, 2018 in the Bavarian Lake District near Munich, Germany.

For more information and to register for the conference, please visit www.sdbday.org.
