Hydrographic Surveys
Underwater terrain mapping, water depth measurement, and submerged feature location for rivers, lakes, and coastal areas.
Who It's For
About Our Hydrographic Surveys
Hydrographic surveys map the underwater environment, measuring water depths, capturing the profile of riverbeds, lake floors, and coastal seabeds, and locating submerged objects and potential hazards beneath the surface. This data is essential for flood risk assessment, infrastructure design, dredging operations, environmental monitoring, and the planning and management of waterways.
Digital Mapping Ltd provides hydrographic survey services across the North East using state-of-the-art depth measurement equipment, providing accurate, georeferenced data that integrates directly with topographic and engineering survey data for a complete picture of the above and below water environment.
Our hydrographic surveys are used by engineers, local authorities, environmental consultants, and infrastructure owners for a range of purposes, from assessing the condition of river channels and managing flood risk, to planning bridge foundations and monitoring the progress of dredging works.
