Drone services in Guadeloupe and Saint-Martin: thermography, LiDAR and pylon inspection
In Guadeloupe, Sentinel prepares the missions, processes the data and delivers the reports; flights are carried out by our partner Antilles Drone or by our Martinique team. Since 2022: thermal surveys of the Creuilly plant in Le Moule, a 327-hectare orthophoto of the Jarry-Houëlbourg wetland for the Conservatoire du littoral, eight ground-mounted plants diagnosed in August 2026 (18,671 panels), and the pylons of the 63 kV Bouillante–Sainte-Rose line. In Saint-Martin we surveyed a site in the port of Galisbay and the surroundings of Grand-Case aerodrome.

Second day on the 63 kV Bouillante – Sainte-Rose line: pylon 36 completed
On 15 July 2026, with Antilles Drone: 178 photos of pylon 36, from the general views and access to the three arms, with the earth-wire anchorage and the spans towards pylons 35 and 37. Deliverable for pylons 36 to 38 handed over on 16 July.

Detailed inspection of pylons on the 63 kV Bouillante–Sainte-Rose line
On 2 June 2026, with Antilles Drone and an Omexom employee for access, on the Trace des Contrebandiers: pylon 37 fully covered at the top of the hill, pylons 36 and 38 photographed from a distance from that position. Pylon 36 was completed on 15 July.

LiDAR ground points at 15 cm spacing for the earthworks studies
The roads and utilities designer noticed height differences between the 2024 and 2025 surveys: his calculations relied on the 2024 photogrammetric contours, which follow the canopy in wooded areas. On 12 February 2026, delivery of the LiDAR ground points over his two 8 m check strips.
