“UAV flights”: main characteristics of the orthomosaics built for each study site. For each flight, radiometrically calibrated reflectance values exist for 5 bands (Red, Green, Blue, Red-Edge, and NIR); Latitude and Longitude correspond to the origin of the raster (north-west corner); Num of geolocated images shows the number of individual overlapping images used to build each orthomosaic. “Spectroscopy/Trait collection”: information on the single-species turfs collected for ground-truthing, leaf spectroscopy, and trait measurements. “Georeferenced extra ground points”: number and functional group of identified vegetation types in the field which were geo-referenced with a differential GNSS system.
