Now you can get high quality water depth data online

- and only pay for what you need!

The Bathymetrics Data Portal enables you to search, purchase and automatically download the best available water depths information for your area of interest in three simple steps.

Conventional methods of collecting bathymetry data usually involve long lead times and physical site surveys – resulting in health and safety concerns, environmental impacts and high costs.


For many parts of global coastal waters, reliable and readily available information about water depths has been insufficient.

Imagine gaining online access to high quality water depth data, and only paying for what you need. The Bathymetrics Data Portal makes it possible to:

Search, purchase and download

accurate bathymetry data directly from our online store to your computer.

Access data ranging from 2m to 90m

Our continuously-expanding global database offers high resolution, detailed data for small projects; as well as large volume, low resolution data for larger projects (for example, global or country wide.)

Reduce costs by only paying for your project area

Search for bathymetric data covering your area of interest, then pay by the square kilometer – without large minimum order costs.

Stay up-to-date with the best bathymetric information

The portal is constantly being updated with new and improved data, providing you with the best available bathymetric information around the world.

Take a quick tour!

Get started!

The Bathymetrics Data Portal is easy to use. In just three simple steps, you will have the data of your choice.

Simply start by searching for data by defining your area of interest on the world map. You will then be presented with the available coverage and be given a quote before proceeding to checkout. Upon registration you will be able to complete the purchase and receive a download link to the data.

“Data is the lifeblood of sustainable development, planning and investment. TCarta and DHI lead the way in inventing new data products like satellite derived bathymetry that have huge significance for better understanding and managing marine and coastal resources for coastal communities and small island developing states worldwide.”

No environmental impact on the survey site

It’s all about the quality

How do we ensure the high standards of our 2m bathymetric data? We first access the best-in-class satellite imagery through market leader DigitalGlobe. Then drawing upon DHI’s expertise and physical-based modelling of the water column, we derive reliable water depths based on these satellite images. TCarta’s hydrographic experience and longstanding reputation in satellite-derived bathymetry set the final seal in assuring the top quality of our product.

Here’s what you need to know about our data:


Our 2m Bathymetry product provides a single depth value for every two meters of the seafloor, as well as an uncertainty measure that indicates accuracy for each data point.


The data can be delivered in any GIS-ready format, but will be delivered as XYZ text files by default, as they integrate well with all domain specific software.


Our 90m Bathymetry product is based on aggregates of bathymetric data from a wide variety of sources, such as navigational and bathymetric charts, ship trackline data, LiDAR surveys, satellite-derived data and sonar surveys. We apply specialised quality assurance techniques to reference each data set against the others, validating values and excluding inconsistent data points – to make the best data available to you.

Who we are

The Bathymetrics Data Portal is brought to you by a joint partnership between DHI, TCarta and DigitalGlobe. Find out more about what we do.

DHI is a global leader in solving the world’s toughest challenges in water environments – using knowledge gained from over 50 years of dedicated research and real-life experience in 140 countries. We have provided satellite-based information of shallow waters for more than 15 years. As with The Bathymetrics Data Portal we have demonstrated our capabilities in providing both intuitive tools and innovative mapping products based on satellite imagery. DHI is responsible for developing the shop functionality, as well as the production of the 2 m Bathymetry product, which is based on proprietary methods to derive water depths with a detail level ranging from 2-metre to 30-metre resolution.

As one of the first commercial providers of high resolution Satellite Derived Bathymetry, TCarta has a long history of creating and supplying water depth datasets, they are a leading supplier of marine geospatial data on an international scale. TCarta orchestrated the creation of the Bathymetrics service, working with DHI to develop The Bathymetry Data Portal and uses their hydrographic experience to complete quality assurance on the 2m Bathymetry product. TCarta’s products also include a global dataset of interpolated 30 - 90m GIS Bathymetry, shoreline vectors and marine base map.

DigitalGlobe is the world’s leading provider of high-resolution Earth imagery, data and analysis. With the most sophisticated commercial satellite constellation in orbit, DigitalGlobe creates the world’s smartest images – giving customers the confidence to make the decisions that matter most. DigitalGlobe is responsible for providing suitable imagery as the basis for deriving reliable water depths.
