  • As part of the Network for Calibration and Validation of Earth Observation data (NCAVEO) 2006 Field Campaign, a Dornier 228 aircraft operated by the Natural Environment Research Council (NERC) Airborne Research and Survey Facility (ARSF) collected CASI-2 data on 17th June 2006. The data was collected between 10:40 am and 12:01pm GMT over Chilbolton, the campaign's study area. The aircraft flew eight adjacent north-south flightlines to cover the whole area, and one east-west across the area, passing directly over the CFARR site. Information about data collection can be found in documentation file '168-GB06-10.pdf' in linked documentation. The Level 3a files in this dataset have been processed using the AZGCORR software package (Azimuth Systems UK) provided by the NERC Airborne Research and Survey Facility. This produced a 2 metre pixel geo-corrected product without the use of ground control points. JPEG images of the Level 3 files are available for each flight line as band 10, 8, 6 RGB false-colour composites. The CASI data has 15 bands. The wavelength and width of these are specified in the associated metadata PDF, in linked documentation. Level 1B CASI-2 files and data collected by the Eagle instrument during the flight are also available through their separate dataset record pages, listed in linked documentation.
