Bathymetrics Data Portal

Coastal environments are some of the most dynamic and constantly changing regions of the globe. Monitoring and mapping these changes is critical to environmental studies and construction activities such as harbours, pipelines and other critical infrastructure in the coastal zone and shallow offshore areas. However, a significant portion of the world’s coastal regions are still poorly mapped or the mapping is outdated.

Avoid the risk of lacking or outdated bathymetric data and quickly deliver up-to-date information on water depth to support time-critical scenarios such as disaster relief efforts with the world’s first Bathymetrics Data Portal. It offers a cost-effective approach to detailed mapping of shallow water areas and unlike field-based surveys, turnaround time is fast, there are no health and safety concerns nor required permitting. Additionally, the data can be integrated with onshore, subsurface and other data in your project and being satellite-based, it’s ideal for use in remote areas and harsh environments.

Instantly access high quality bathymetry data

Our satellite-based high resolution bathymetry products provide a single depth value for every two to 10 meters of the seafloor, as well as a certainty indicator for each data point’s accuracy. We have also 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.

Reduce data costs

Why pay for data you don’t need? With the Bathymetry Data Portal, data can be purchased by the square kilometer.

Start using your data right away

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.

Access both local and global scale data

Tap into our comprehensive database for high resolution data for localised projects as well as large volume, lower resolution data for global and international projects.

Have confidence your data is up-to-date

The portal is constantly updated with new and improved data, providing you with the best information available. If we don’t have your area of interest covered, let us know and we will source it for you.

"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."

Key application areas

The Bathymetry Data Portal is relied on by:

  • The modelling community who require accurate bathymetry for high quality hydrodynamic modeling of the coastal zone
  • Engineering companies working in the coastal zone for use in the initial planning phase and as a first screening before conducting costly field campaigns
  • National authorities and hydrographic offices who need up-to-date information about territorial waters to minimise navigational hazards within their area of responsibility
