At DHI GRAS, we value the sustainability of seas, oceans and waterways, which this year is marked by World Hydrography Day with the theme "Bathymetry - the foundation for sustainable seas, oceans and waterways".

At DHI GRAS, we use satellites to derive bathymetry data from all over the world. A significant part of the global underwater coastal zone is still unmapped or subject to dynamic changing seabed features. This makes it difficult for ships to navigate safely, and is a big cause for concern for both human lives and potential environmental disasters from groundings. We are working to minimise these risks.

We are a leading global provider of satellite-derived bathymetry, and with modern satellites and advanced physical modeling of the water column, it is possible to derive reliable water depths in shallow waters at low costs with no risks associated.
