Hydrographic Survey
Lagos is defined by its waterfront. We survey lagoon, creek, and coastal corridors — the same 200m waterfront and 100–200m highway corridors the NIS fee schedule zones separately — for reclamation, marina, and waterfront development projects.
Positioning and depth data collected together from the survey vessel.
What it looks like on the water
Depth and position recorded together, then turned into a chart.
GNSS positioning is combined with echo-sounder depth readings along planned survey lines, then processed into a bathymetric chart.
Includes
Bathymetric survey, shoreline mapping, waterfront boundary determination.
Typical clients
Waterfront developers, marina operators, dredging & reclamation contractors.
Deliverable
