Accuracy evaluations and assessments of ALOS products.
Advanced Land Observing Satellite (ALOS, the nickname "Daichi") was successfully launched on January 24, 2006. After the initial mission check, the initial Calibration and Validation (Cal/Val) operation, which involve sensor characterizations, image quality measurements, and accuracy improvement of the standard products, were carried out from May 16 to November 23, 2006.
After the initial Cal/Val operation, JAXA is continuously evaluating the standard products to improve those absolute accuracies. As the results of Cal/Val, the accuracies of standard products processed at JAXA Earth Observation Center (EOC) can be found at
