Hydrographic Surveys, Bathymetry & Sediment Evaluations

Uncrewed platforms are suited to smaller basins, creeks, and sites where safety, water quality, or minimal disturbance rule out putting a person in the water. Manned platforms cover more ground per day and handle larger, more sheltered water bodies, debris, vegetation, and current better. The choice is made against site conditions, not a default preference for one platform.

Every survey carries a stated confidence level as part of an internal QA process, tied to the instrument and method used — not an unsupported accuracy claim, and not held to a navigational-charting standard your decision doesn’t actually require.

Yes. Coverage rate, endurance, and access limitations are disclosed plainly during scoping, including cases where a hydrographic survey isn’t the appropriate way to answer your question — we’d rather flag that upfront than have it surface as a limitation on site.

Equipment access is the easy part — comparable hardware is available to most providers in this market. The differentiator is the interpretive step: turning raw sonar and positioning data into a number that holds up to engineering, regulatory, or financial scrutiny. That comes from a body of completed, cross-client work, not from the instrument itself.
