High quality and ready-to-use data

The Bathymetrics Data Portal uses the best-in-class satellite imagery and state-of-the-art physical based modeling. Backed by 15 years of experience it has a proven track record for delivering high quality reliable water depth information. This is what you can expect from our data:


Our satellite-based high resolution Bathymetry products provide a single depth value for every two to ten meters of the seafloor, as well as a certainty indicator for each data point’s accuracy.


The default XYZ file format ensures smooth integration with all domain specific software. Plus, the data can be delivered in any other GIS-ready format.

Large-scale coverages

We have included several large-scale datasets for direct download, making it easy for you to instantly get bathymetry data for your area of interest in a ready-to-go data format.


With The Bathymetrics Data Portal, high resolution and accurate global bathymetric data is now within easy reach.

Simple, online ordering and delivery for rapid data deployment

Integration with onshore, subsurface and other data in your project

Free from mobilisation and permits; no international border issues

Off-the-shelf GIS-ready bathymetry for rapid delivery

Reduces time and risk planning for marine and seismic surveys

Free from environmental impact on the survey site

Use cases

The Bathymetrics Data Portal has provided many companies and organizations with valuable bathymetry data.

We are particularly proud of the contributions that we made to the following projects:


The Danish Environmental Protection Agency

Challenge: Lacking detailed and up-to-date bathymetry data for the Danish coastal areas. The bathymetry data is required for detailed modelling and management of the inner Danish waters.

Solution: Expanding the existing coarse and dated Danish bathymetry model with up-to-date and high resolution satellite-derived Bathymetry making it possible to perform detailed numerical modelling in support to the Danish Water Plan.

Dragør, Denmark

NIRAS/ Dragør Municipality

Challenge: Performing a detailed numerical modelling study of waves and water levels in Dragør harbour under a tight deadline, but lacking input data in a sufficient level of detail and accuracy.

Solution: Using high resolution satellite-derived bathymetry delivered within a few working days to obtain detailed knowledge of sand waves, longshore bars, reefs and other similar features providing solid model results, while keeping the costs low.

Antigua & Barbuda

UK governmental institutions

Challenge: Analysing the effect of Hurricane Irma and securing marine resources that support sustainable economic growth and poverty in the Commonwealth Small Island Developing States.

Solution: A 2m Satellite-derived Bathymetry model was derived for the islands, one from before the hurricane hit, and one after it had passed, to be able to identify changes caused by the storm and re-establish safe passage for ship traffic.

“NIRAS has used high resolution bathymetry data from DHI GRAS for a detailed wave and water level study in Denmark. The bathymetry data was derived from satellites in an impressive high resolution. With the surface coverage, it was possible to see detailed morphological variations such as longshore bars, sand waves and other similar features, which are not normally seen in traditional measurements with that level of detail. It clearly made the subsequent modelling much more valid. The product is price-wise very competitive compared to traditional survey methods.”
