The ground truth behind serious projects.
We plan, acquire, process and deliver site investigation data that engineers, operators and investors can build on — from the land surface down through the seabed.
A serious partner for land, sea and every layer beneath them.
GeoLegacy Survey is an integrated survey and geospatial engineering company. We plan, acquire, process and deliver site investigation data for energy, marine, infrastructure and real estate projects across Nigeria and West Africa.
Our teams are built around one promise: field-verified data, delivered to engineering grade, on schedule. Every deployment — onshore or offshore — runs on calibrated instrumentation, disciplined QHSE protocols and a single accountable line from scope to final report. That is what makes our work something engineers, operators and investors can actually build on.
