Hydrography and Navigation

Navigators at sea frequently face challenges such as outdated maps, shifting seabed conditions, or uncharted underwater shoals. Costly and time consuming traditional surveys as well as the changing seabed hinder hydrographic offices from maintaining accurate navigation data. Increasing maritime traffic and regulatory demands add further pressure.

Earth Observation (EO) provides a solution by delivering frequent, high-resolution satellite imagery to detect underwater hazards, monitor coastline changes, and update bathymetric data efficiently. Using our expertise in EO-powered analytics, mapping and monitoring the seabed with satellite-derived bathymetry ensures fast and cost-efficient information. This enhances maritime safety, reduces surveying costs, and supports regulatory compliance. With our tailored solutions, clients can make data-driven decisions for more efficient and secure marine navigation.

Storms, floods and other natural disasters often have serious impacts on the nearshore seafloor and environment. Large amounts of sediments move or underwater habitats are destroyed or seriously impacted, often within a single day. Rapid assessment of these changes is a big challenge for agencies, but plays an important role in quantifying losses and assisting in the decision-making process.

With Earth Observation, we can map the pre-and post-storm state of an area within a few days, highlighting the potential zone of accretion or erosion and estimating volume changes.

Any coastal construction project and management plan includes the modelling of storm surges, waves, and currents. For all their predictions, modelers require accurate coastal topography and bathymetry data. This applies especially for the very shallow coastal zone.

EOMAP’s bathymetry and elevation models can provide seamless topo-bathy models and deliver accurate and up-to-date information in these sensitive zones. For providing these coastal models and data, we do not require any on-site activity.

Therefore, we can provide the information faster and at a much lower cost compared with on-site surveys. Coastal engineers and planners can thus count on a robust tool for the planning and hydrodynamic modelling phase of coastal constructions.

Regional and national authorities need to comply with legislation, such as the Marine Strategy Framework Directive, the EU Biodiversity Strategy or the European Green Deal.

Earth Observation supports regular monitoring and reporting in a rapid and cost-efficient way using the spatio-temporal information of satellite data. At EOMAP, we observe habitats and monitor parameters which impact them. Moreover, we characterise coastal morphology. After combining and interpreting this data with related coastal information, data and publications, we often engage in workshops with our clients. Together, we develop solutions for smart and efficient reporting routines in line with directives of the European Commission and other legal bodies.

Authorities and organisations on regional, national and international levels not only benefit from our robust data and services. They also value streamlined workflows and efficient reporting routines.
