Why local

A team based in Cotonou — not a vendor passing through.

ANAC authorisations on file

Every flight we operate is declared to Benin's Civil Aviation Authority. We handle SORA risk assessment, NOTAM filings and specific authorisations for sensitive zones (CNHB, Autonomous Port, Cardinal Bernardin Gantin International Airport).

Pilots and engineers on the ground

The technical team lives and works in Cotonou. No middlemen, no outsourcing: you talk directly to the people who fly the drone, process your data and deliver your results.

On site within 72 h

For any site in Greater Cotonou, we can be on the ground within 72 hours of quote approval. For urgent missions (blocked construction site, incident, ad hoc inspection), we prioritise scheduling.

Deep knowledge of local sites

Place de l'Amazone, Route des Pêches, GMK Stadium, Cadjèhoun business district: we've already mapped Cotonou's main sites. That knowledge translates into fewer surprises and tighter budget framing.

Service area from Cotonou

From our Cotonou base, we cover Littoral, Atlantique and Ouémé departments with immediate mobilisation (≤ 72 h). For missions further north (Zou, Borgou, Collines), we deploy the team with temporary on-site accommodation — the operational fee stays transparent and is fixed at quote stage.

Drone regulation in Cotonou

Cotonou hosts several constrained airspaces: Cardinal Bernardin Gantin International Airport, military heliport, port zone. For every mission, we run the SORA risk assessment, file NOTAMs where required and liaise with ANAC ahead of time.

  • ANAC Benin Prior flight declaration, specific authorisations for dense urban areas and sensitive sites.
  • SORA analysis Systematic assessment of ground, air and population risks before every urban mission.
  • NOTAM if required Notice to Airmen filed for flights near airport or military zones.

Frequently asked questions — local

Drone in Cotonou — your questions

What's your turnaround for a mission in Cotonou?

For a site in Greater Cotonou (Littoral, Atlantique), we mobilise the team within 72 hours of quote approval. Spot inspections and weekly construction monitoring are scheduled ahead with a recurring slot.

Can you fly a drone in dense urban areas of Cotonou?

Yes, with constraints. We run a specific SORA analysis, file an ANAC declaration and, depending on the zone, a NOTAM. Neighbourhoods close to the airport or military zones require additional authorisations — we handle those upstream.

What accuracy do you reach on a Cotonou mission?

On photogrammetry: XY < 3 cm and Z < 5 cm with RTK GCPs. On airborne LiDAR: 200 points/m² standard, up to 800 pts/m² in high-density mode. For stockpile or earthworks volumetrics, the tolerance is ± 1 %.

Do you work with Beninese public administrations?

Yes. We've delivered missions for ANPT (UNESCO Royal Palaces of Abomey), SoNaMA (Okpara farm) and SBEE (HTB power lines). We know how to handle administrative documentation, ANAC traceability and deliverables compliant with public-sector standards.

What are your delivery times after the flight in Cotonou?

Orthophoto and DTM/DSM within 5 to 10 business days depending on volume. 3D modelling and digital twin within 15 days. Construction monitoring reports: J+2 after the flight for standard weekly reports.
