Surveying Shallow Water from Space – easy and online

EOMAP launches SDB-Online, the new WebApp for Satellite-Derived Bathymetry

SDB-Online is the new cloud-based WebApp to create high-resolution bathymetric grids for shallow waters and the first of its kind. It builds on EOMAP’s expertise in Satellite-Derived Bathymetry (SDB), a technique to map water depth from space, avoiding time consuming and costly on-site surveys. With SDB-Online, coastal engineers, surveyors, modellers or scientists can create high-resolution bathymetry grids 24/7, from the comfort of their desks.

“EOMAP’s SDB-Online is delivering fast and accurate results without the need of ground control data, processing 10 scenes in less than one hour. The “Combine” option (multi-image processing) is a game changer in challenging locations, especially with frequent cloud cover or heavy vessel traffic”, says Véronique Jégat, Senior Geo-Data Engineer at Fugro.

Underwater topography – bathymetry – is crucial for many different coastal stakeholders: On the basis of bathymetric data, coastal engineers calculate and plan their projects, surveyors decide where to set up on-site campaigns, modellers analyse and predict coastal dynamics, while scientists study seabed morphology and benthos. So far, they often had to either perform work and cost intensive on-site surveys or to rely on insufficient data from other sources. SDB-Online helps: It enables the above users to access high resolution bathymetric grids of shallow waters without on-site surveys – rapidly and easily.

“Experts managing or studying coastal shallow waters will experience an incredible time and information gain: Within minutes they can trigger automated processing routines and receive high-res bathymetry data for their projects“, says Mona Reithmeier, SDB-Online manager and SDB expert at EOMAP.
