GaoFen-2
GaoFen-2 was launched by the China National Space Administration (CNSA) on August 19, 2014. It was an improvement on the 2-meter resolution satellite, GaoFen-1, launched in 2013. GaoFen-2 is part of CNSA’s high-resolution satellite constellation that also includes SuperView-1, collecting 80-centimeter panchromatic and 3.2-m 4-band multispectral (i.e. blue, green, red and near infrared) imagery.
GaoFen-2’s massive 45-kilometer swath width coupled with 80-cm resolution makes it a unique choice for large-scale mapping. Gaofen-2 is equipped with 2 PAN/MS cameras, that can collect images with resolution of 0,80 m (nadir) in panchromatic and 3,24 m (nadir) in the multispectral bands.
GeoFen-2 collection of the 4-band multispectral data makes it ideal for precision agriculture, forestry and spectral analysis. Its objective is to provide high accuracy geographical mapping, land and resource surveying, environment change monitoring, as well as for large area post-event assessment, including natural disasters and crisis management.
