AVNIR-2 (Advanced Visible and Near Infrared Radiometer type 2)
AVNIR-2 is a successor to AVNIR that was on board the Advanced Earth Observing Satellite (ADEOS), a visible and near infrared radiometer for observing land and coastal zones.
AVNIR-2 image over Tanegashima and Kagoshima Prefecture
The image appears as the same color as it is seen by people’s eyes, with 10m resolution. For example, the image distinguishes the beach to the shoal along the coast, inland plants and constructions.
The image also shows Takezaki-Observatory in Minami-Tanegashima and Huge Rocket Launch Site there very clearly. It also provides information by integrating four bands from a visible to near infrared radiometer to know the condition of vegetation and forests as well as land use.
Observation Date ： 2006/02/17 10:50am(JST).
