Sinnamary
On the RN1 between Kourou and Iracoubo, Sinnamary stretches from the estuary to the savannas and the forest; the Petit-Saut dam, within the municipality, has its own page. In September 2023 we flew four LiDAR intercalibration flights there, at 65, 80, 95 and 110 m above the forest of the Paracou research station; in 2024 we inspected the 484 supports of the Sinnamary–Iracoubo lot of medium-voltage lines; drew the 1:500 plan of the Corossony solar plant in September 2024, then, in December 2025, once the modules had been removed, surveyed its 1,472 concrete footings at 2 mm per pixel; surveyed 48 ha of forest by LiDAR for the Espace-Dev research unit; covered 66 ha at Pointe Combi in May 2026; and produced the virtual tour of the Savane des Pères plant, whose construction site we had photographed and mapped before it was commissioned in 2019.

Images of the Petit-Saut biomass plant for Voltalia’s communication
A selection of views extracted from the August 2025 360° panoramas, then full-resolution files for the inauguration’s printed visuals.
Capture of a telecom site for its digital twin
On 28 May 2025, with an agent of the operator on site: photogrammetric orbits around the water tower that carries the antennas, four 25-photo panoramas above and below the top, indoor and outdoor 360° tours. 3D model then computed by the operator’s digital-twin contractor.
