Uniformity characterization of land test sites used for radiometric calibration of earth observation sensors

摘要

Image data at 1-km scale simulated from SPOT HRV imagery were used to study the radiometric uniformity of the vicarious calibration test site at the Railroad Valley playa in Nevada and a potential site in the Newell County rangeland area in Alberta.Descriptive statistics of selected sites indicate that both locations could be equally useful as calibration sites for large footprint sensors.
