AbstractThe feasibility of using single data sets of spatially extensive hyperspectral imagery to carry out vicarious calibrations for multiple Earth Observation sensors is examined. Results are presented based on data acquisition campaigns in Nevada in June 1998 and in Alberta in August 1998, which included ground-based measurements, satellite imagery, and airborne hyperspectral data in all cases. A rangeland test site in Newell country region of Alberta is tested for its suitability as a new type of calibration test site for satellite sensor systems. The Railroad Valley playa in central Nevada is a more established calibration test site that serves as a good setting for the methodology proof-of-concept and provides a good comparison for the assessment of the rangeland site. The airborne hyperspectral sensor used to generate the reference data sets is the compact Airborne Spectrographic Imager (casi) system. This paper highlights the formulation and implementation of the new methodology, the data sets generated to date, and initial calibration monitoring results obtained for NOAA-14 AVHRR, Landsat-5 TM, SPOT-1 HRV, and SPOT-2 HRV.
