We provide radiometrically corrected hyperspectral data from the AISA Eagle and Hawk instruments; ground height information from the Leica ALS50-II; and digital photography. We additionally supply DEM data with deliveries. We undertake regular calibration of the sensors and preform quality control on all processed data prior to delivery.
