Providing accurate maps of the coastal zone for safe navigation of ships with satellite-derived bathymetry

Satellite-derived bathymetry for guiding nautical navigation
Providing accurate maps for the safe navigation of ships
The challenge:
Greenland Pilot Service provides navigational safety services in the Arctic region and their strategy is to contribute to a safe development of the cruise industry in polar regions.
They embark experienced and licensed Polar Code Compliant Pilots on board the cruise vessels. The Pilots contribute with local knowledge and experience, to strengthen the bridge team, ensuring a safe and effective operation.
The 24/7 manned operations center in Nuuk carries out all mandatory Risk Assessments, and continuously updates the pilots with daily information on weather and ice.
To be able to operate safely and ensure best practice, they needed updated information about coastlines and submerged hazards in the poorly charted shallow coastal area around Skjoldungen, Greenland.
Project highlights:
Updated and accurate mapping of coastlines including at high and low tide
Location and size of submerged hazards mapped with clear depiction of small and large submerged hazards
Updated spatial information ensuring safe transport of vessels, ideal for large and remote areas

Thomas Bøggild
With the help of satellite-derived bathymetry from DHI GRAS we were able to make a proper navigational risk assessment enabling our clients to safely access the remote and poorly charted waters around Skjoldungen. DHI GRAS did a great job in helping us understand the value of the data and delivery was fast and on time
In more detail..
We were commissioned by the client to provide them with accurately mapped coastlines at both low and high tide, as well as identify submerged hazards, such as reefs, rocks and sand banks.
Sentinel images provided the raw data, which were then analysed and validated. The information derived from satellites is much more accurate than existing nautical charts in the Arctic and allowed Greenland Pilot Services to safely enter the waters around Skjoldungen.
