Pre-processing Study of the Airborne Imaging Spectrometer Data Based on the Classification of Land Use/Land Cover——A Case Study of Yixing City

Taking Yixing district in Jiangsu Province as an example, the pre-processing steps such as data importing, image rotation, calibration of illumination aberrance, calibration of relative reflectivity, rectification of geometry and strip mosic based on the classification of land use/land cover are done. The study shows that experiential linear calibration model (EL) is better than the other two models. The map composed by many strips is inosculated with the data base of land use.
