摘要:
Information regarding Land cover and change (LCC) over time is essential for a variety of Societal Benefits Areas (SBA), such as environmental change analysis, geographical condition monitoring, urban and rural management, earth surface process modeling, and sustainable development. Since the middle of 1990s, the international scientific communities have devoted tremendous efforts to Global Land Cover (GLC) mapping, and developed a number of coarser resolution (ranging from 300-m to 1 km) data products. As these products could not provide sufficient spatial details and are far from satisfactory for many applications,the Groupon Earth Observations (GEO) and some other international organizations called for actions to move towards finer resolution GLC mapping and monitoring in 2010.In order to meet increasing user needs, China launched an operational GLC mapping project and produced a 30-m GLC data product, GlobeLand30, with 10 classes for years 2000 and 2010 . In September 2014, GlobeLand30 was donated by China to the United Nations for open access and international sharing. It was reported by Nature as “China: Open access to Earth land-cover map” and recognized by international experts as “a milestone achievement in the Earth Observation and open geo-information access. In order to further report the innovative developments and applications of GlobeLand30 ,Science China Earth Sciences has published a special issue, entitled “GlobeLand30 remote sensing mapping innovation and big data analysis”, in the end of 2016.
