AVNIR is a visible and near-Infrared multispectral imager on ADEOS. AVNIR observes the earth surface with the spatial resolution of 16 meters covering the wavelength range of 420 nm890 nm with 4 bands. It has also one panchromatic band of 520 nm690 nm with the spatial resolution of 8 meters. AVNIR scans about 80 km swath width along the cross track, using the large lineararray CCDs with 5, 000 pixels (multispectral band) and 10, 000 pixels (panchromatic band). The observation area is limited because of narrow swath width. In order to compensate this disadvantage, the pointing capability acquires the wide range of target within +/- 40 degrees around the nadir. In this paper, on-orbit calibration results of AVNIR and some application analyses results will be described.
