Orthomosaics of the Esnandes Salt Marsh (~1 km²) acquired in September 2024 and September 2025

Orthomosaics of the study area were generated by drones on 19 September 2024 and 18 September 2025. They were created from 895 images (2024) and 1,282 images (2025), captured at altitudes of 120 meters (2024) and 100 meters (2025) using the DJI Mavic 3E RTK (2024) and Mavic 3M RTK (2025) drones. The ground resolutions were 3.19 cm/pixel (2024) and 2.63 cm/pixel (2025). The surveyed area covers approximately 1 km², and the orthomosaics were resampled to a resolution of 10 cm/pixel.

Statement: RGB images acquired using the Mavic 3E RTK and Mavic 3M RTK drones from the LIENSs UAV plateform.The drone acquisitions were carried out by Nicolas Lachaussée (2024) and Natacha Volto (2025) from the LIENSs UMR Drone Platform. Photogrammetric processing was performed by Natacha Volto (LIENSs) using Agisoft Metashape software. These drone surveys were conducted as part of the ESA Coastal Blue Project, coordinated by Christine Dupuy at the LIENSs Laboratory.
