Saint-Martin
In Saint-Martin we work from Martinique. For an energy company, we surveyed a site in the port of Galisbay by photogrammetry in early November 2024 (1.5 cm per pixel), then by LiDAR on 18 March 2025 to recover the ground beneath the vegetation. In April 2026, for the operator of Grand-Case aerodrome, we surveyed a wooded area north-west of the runway by LiDAR and photogrammetry ahead of its extension project: flights on 14 and 15 April from outside the platform, at 30 m maximum, in liaison with the AFIS and with an observer from Tilaya Drones, then delivery on 17 April of a DWG tied to the existing runway survey.

LiDAR survey beside the runway at Grand-Case aerodrome
Wooded area of about 8 hectares beside the runway: control points on 13 April 2026, photogrammetry and LiDAR flights on the 14th and 15th at no more than 30 m, in coordination with the AFIS; 3 cm orthophoto, ground points at 2 m spacing and existing drawing re-registered in RGAF09 delivered on 17 April.

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.

On 18 and 19 March 2025, over the project’s priority area, without the port, the batteries having been shipped without using aircraft. Deliverables from 31 March to 3 April: digital terrain and surface models at 15 cm, ground and above-ground point clouds, DWG drawings of the ground points.
