| Abstract: | GlobeLand30 is the world's first 30-meter resolution global-land cover dataset developed by China under the support of 863 key project.It contains ten major land cover classes:cultivated land,forest,grassland,shrub-land,wetland,water bodies,tundra,artificial surfaces,bare land and permanent snow and ice,with two base-line years (2000 and 2010).A total classification accuracy of 83.5％ was given by the third party institutions.On September 22nd 2014,Chinese government donated GlobeLand30 m UN,as a tangible means assisting UN systems organizations and member states in their scientific decision-making and sustainable development.There are up-to-now more than 6,000 users from almost 120 countries,GlobeLand30 has significantly promoted the data sharing of earth observation and geo-information in the world.This paper presents the major technical innovation of GlobeLand30,accuracy assessment,and its data sharing. |
