AVNIR is a high spatial resolution imager on ADEOS with four multispectral bands covering visible range (blue, green and red band) and near-infrared range, and one panchromatic band. It has high spatial resolution observation capability with 16 m for multispecral bands and 8 m for panchromatic band. AVNIR has also a multi-viewangle observation capability (pointing function) with 40 degrees from nadir. These two characteristics of AVNIR enables to produce high quality land cover/use maps and digital elevation models (DEM). Besides these two pratical products AVNIR is expected to produce scientific parameters including space reflectance and surface reflectance which would play an important role in assessing radiation and energy budget on the earth surface. Also as science data sets AVNIR is expected to produce different types of thematic maps including wetland map, vegetation map and hazards map. This paper describes the function and the role of AVNIR in the ADEOS science program, and also introduces the current status of AVNIR data production.
