About GF-2

GF-2 (short for Gaofen-2) was launched on August 19, 2014. This satellite has collected 14.3 million square kilometers imagery of Earth land surface. It is a very high-resolution optical imaging satellite with 0.8 m panchromatic and 3.2m multiple spectral resolution. The width of one pass at nadir is 45 km. The imagery has widely applied for governmental services, marine surveillance, precision agriculture and forestry, emergency management, education and research.
