Drone Porto-Novo — photogrammetry, LiDAR and urbanism

OHM WORKS operates in Porto-Novo and across Ouémé department for urban mapping, heritage surveys, construction monitoring and infrastructure inspection. As Benin's political capital, Porto-Novo is 30 minutes from our Cotonou HQ — fast mobilisation, XY < 3 cm accuracy.

Why local

Political capital, immediate neighbour of our HQ.

ANAC authorisations on file

Porto-Novo hosts several sensitive institutions (National Assembly, Presidency, Prefecture). We handle authorisation requests with ANAC upstream and coordinate with local authorities for restricted zones.

Team 30 minutes away

Porto-Novo is 30 km from our Cotonou base. For a one-off intervention, the team is on site within half a day — useful for fast diagnostics, condition surveys or urgent missions.

Quote within 48 h

As with every mission, we provide a costed quote within 48 hours of receiving the brief. For recurring missions (weekly construction monitoring), we negotiate an annual flat fee.

Heritage and urban fabric studied

Porto-Novo preserves a rich colonial fabric (Great Mosque, Honmé Museum, Cathedral, Afro-Brazilian façades). Our acquisition method is calibrated for dense historic city centres.

Our drone missions in Porto-Novo

In Porto-Novo, demand centres on urban mapping (renovation of the colonial fabric, extension planning), heritage (mosque, museums, façades) and inspection of public infrastructure. Our four most-mobilised disciplines:

First mission in Porto-Novo?

Porto-Novo is a priority target for our local development. We're actively working with several public and private actors on ongoing projects. Be OHM WORKS' first public reference in the capital.

Coverage of Porto-Novo and Ouémé

Mobilisation from Cotonou in 30 minutes. Our radius covers the entire Ouémé department (Porto-Novo, Adjarra, Aguégués, Avrankou, Bonou, Dangbo, Sèmè-Podji) and southern Plateau (Pobè, Sakété, Adja-Ouèrè).

Drone regulation in Porto-Novo

Porto-Novo concentrates sensitive political institutions (National Assembly, Presidency, Constitutional Court). Any drone mission downtown requires prior authorisations — we handle the process with ANAC, prefectural authorities and, where necessary, security forces.

  • ANAC Benin Mandatory prior declaration, sensitive urban zone with political institutions.
  • Administrative centre Enhanced SORA analysis — population density, administrative buildings, security.
  • Authority coordination Advance notification of security forces and the Prefecture for downtown missions.

Frequently asked questions — local

Drone in Porto-Novo — your questions

How long to mobilise to Porto-Novo from Cotonou?

Mobilisation in 30 to 45 minutes depending on traffic. For a one-off mission (diagnostic, condition survey, fast inspection), the team is on site within half a day. For planned missions, we agree on an optimal slot.

Can you fly a drone near the National Assembly or the Presidency?

Not without specific authorisation. These zones are under heightened protection. For missions in their vicinity, we coordinate with ANAC, the Prefecture and security services 2 to 4 weeks upstream. For standard urban fabric (residential, commercial), a basic ANAC declaration suffices.

What accuracy for a heritage survey in Porto-Novo?

XY < 3 cm orthophoto accuracy, Z < 5 cm DTM, 3D mesh resolution ≤ 2 cm per side. Sufficient for architectural analysis (façade pathologies, restoration monitoring, bas-relief study).

Do you work with the administrations of Porto-Novo?

Our ANPT reference (Royal Palaces of Abomey, UNESCO site) attests to our ability to deliver missions for Beninese public administrations. We know how to handle documentation, ANAC traceability and deliverables compliant with public-sector standards.

Which mission types have the most potential in Porto-Novo?

Three high-potential angles: 1) 3D modelling of heritage buildings for conservation programmes, 2) fine urban mapping for development projects, 3) construction monitoring on major institutional projects.
