GEO-K supports ESA for Sentinel-2 data calibration using drones
Our UAV equipped with MAIA multispectral sensor and ILS (Incident Light Sensor) flew on 26-11-2020 at 10:03 UTC over selected test site, overlapping exactly the passage of Sentinel-2 satellite. The UAV altitude was of 90 m with a GSD of about 5 cm and a FOV of 60 m × 45 m.
The flight has been carried out in the contex of QA4EO ESA project which aims to tackle the challenges associated to surface reflectance and BRDF validation using advanced UAV-based techniques.
New flights and data elaboration are scheduled in the next months.
