Bathymetry is the measurement of depth of water in oceans, seas or lakes. The Bathymetrics Data Portal service is focused on the coastal marine environment for the global market.
A web-based service has been created to provide immediate, off-the-shelf, online access to bathymetry derived from very high resolution satellite imagery. In order to meet production needs at a truly global scale an efficient production environment has been established with focus on efficient work flows and reduction of operator involvement.
There is currently a lack of shallow water bathymetric data around the world due to the high costs, lead-time, and health and safety issues involved in collecting this data using the more traditional data collection methods of Multi Beam Echo Sounder (MBES) from boats or Light Detection and Ranging (LiDAR) from aircraft. This satellite derived data service is of great interest to users globally across a number of sectors for use in activities such as feasibility and design of marine and coastal infrastructure, charting, construction and environmental impact studies.
The users are all active on a global scale and cover a large range of the potential market segments for Satellite Derived Bathymetry (SDB). The market sectors covered are 1) Large Infrastructure Construction, 2) Marine Science and Technology Consultancy, 3) Seismic Surveying Company, and 4) a leading online Marine Data Provider. Alongside our Involved users, sales have also been made into the Oil & Gas, Government, Environmental and Navigation sectors.
Common for all the users are their interest in SDB since it offers a faster and more cost effective solution compared to traditional bathymetry collection.
Our four involved users have varying needs and operational scenarios. These are summarised, by user, as follows:
User 1, Worldwide
User 2, UK Overseas Territories and Caribbean
User 3, Arabian Gulf and Red Sea
User 4, Worldwide
The service has validated the business case for provision of an off-the-shelf satellite derived bathymetry service. By engaging directly with customers and involved users throughout the Demonstration Project, the suitability of the proposed service has been demonstrated.
The service focuses on the following key elements:
Through an agreement with DigitalGlobe, the service utilises access to WorldView-2 and WorldView-3 imagery to create depth values for every 2 metres, to water depths of 20 metres, where conditions allow.
An overview of the system is shown in the image below.
The development and delivery of our web-based, off-the-shelf, Satellite Derived Bathymetry service to our users requires the integration of 3 space assets:
The demonstration project has been completed, successfully passing the testing phase, and pre-operational usage period. A web portal is now available for searching and instant purchasing of bathymetry data: https://bathymetrics.shop
A Satellite Derived Bathymetry work flow has been developed that is efficient, and involves rigorous quality assurance and quality control procedures. All Satellite Derived Bathymetry data is provided with an indication of uncertainty, which is of great value to users.
Alongside 2m resolution Satellite Derived Bathymetry, The Bathymetrics Data Portal also provides instant access to 90m resolution bathymetry data. Customers can therefore access data, even in locations where satellite technology is not viable or feasible.
