China 30m-resolution Global Land Cover Map in 2012

摘要

On 23~rd July 1972, the Earth resource technology satellite, ERTS-1, later renamed as Landsat-1, was launched by the United States. Ten years later, the US launched Landsat-4 carrying onboard the new sensor, Thematic Mapper (TM), with a ground resolution of 30m. The Landsat series of satellites have acquired approximately 2.9 million scenes of images across the globe. Although successful applications of Landsat data have been reported in tens of thousands of papers and various governmental reports, so far not a single map has been produced on a specific theme for the whole world using Landsat data.
