  • 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. This dataset holds the 8 Level 1b hdf files which have been produced, containing all relevant VGroup metadata, navigation and data to process the complete flightline using the azgcorr software package. See the "read me" document in linked documentation for the command lines for each flightline and further information on how to view the data. You will also require the ancillary file osgb02 for inclusion in the command line and a high resolution DSM (Digital Surface Model), such as provided by the Nextmap 5m DSM dataset. Level 3a 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.
