Hyperspectral, 8-band, HR, Agriculture & forest-oriented

ZY-1 02D (short for ZiYuan-1 02D, also named ZY-1E or ZY1E) was launched on September 12, 2019. It is equipped with two cameras, one is VNIR camera (VNIC) and the other is hyperspectral camera (AHSI). The VNIR camera has panchromatic and eight multispectral bands, and it has a large view field, with 115 km swath width. The hyperspectral camera has 166 bands, and its swath width is 60 km. It's mainly applied in investigating land resources, emergent monitoring and supervising services, and it also provides supports for disaster deduction, environmental protection, housing, transportation, agriculture, forestry, marine and mapping.
