An area of asphalt, approximately 3m by 3m in size, within the CFARR perimeter was used as a persistent validation target and frequent reflectance measurements made as part of the (Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The centre British National Grid co-ordinates of this validation target, which can be distinguished in the CASI images, are (BNG Easting, BNG Northing) 439335.00, 138586.00. A trolley-mounted GER1500 dual field-of-view spectroradiometer was used to measure the HCRF of the asphalt validation target between 10:54 and 11:38 GMT on the 17th June.
This dataset includes reflectance spectra of oilseed rape collected from Big Croft field, near Chilbolton, as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data was collected on the 18th June, using an ASD N4406 instrument. Please note that all raw spectra files collected during the NCAVEO campaign (labelled ***R_ASD0606**.***) have incorrect dates, indicating them to have been collected in July rather than June. The day of month and time (UTC) are correct in all cases. All other files (FSF spreadsheets and Excel/ENVI summary outputs) are also marked with the correct 15-18th June 2006 dates.
