Hydrographic Survey

Bathymetric mapping for reservoirs, riverbeds, and coastal infrastructure.

Talk directly with our survey team about this service.

We provide precise and reliable hydrographic surveying solutions using advanced bathymetric and satellite positioning technologies. From river and reservoir depth measurements to detailed underwater terrain mapping, we deliver accurate bathymetric data to support hydropower development, dam planning, river engineering, and water resource management. Hydrographic data acquisition using GNSS-integrated echo sounders, bathymetric measurements, and underwater topographic mapping tied to established horizontal and vertical reference datums.

Questions about Hydrographic Survey?

What is included with Hydrographic Survey?

A Hydrographic Survey engagement is scoped to your site and decisions. Typical handover items include Hydrographic Survey Data, Water storage capacity tables, Bathymetric Maps and Depth Contours, River and Reservoir Cross-Sections, Longitudinal Profiles, Water Depth and Elevation Data, GIS-Compatible Spatial Data, CAD Drawings and Survey Maps, Technical Survey Report, along with the supporting checks and metadata agreed during planning.

What information do we need to prepare a proposal?

Share the site location or coverage area, intended use, required accuracy or output, access constraints, and target schedule. If some details are still unknown, we can help define them during the first consultation.

How do you choose the method and confirm quality?

We plan Hydrographic Survey around the terrain, project tolerance, and how the results will be used. The proposed capture and verification steps are agreed before fieldwork, then checked against the project control and acceptance criteria.
