摘要：The Geospatial Information Authority of Japan is conducting a Global Mapping Project, and is serving as the Secretariat of the International Steering Committee for Global Mapping. After the release of Version 1 of the Global Map in 2008, we have developed Version 2 of the Global Map, and more and more countries and regions have released their Global Map data sets. In addition, Global Land Cover and Vegetation (Percent Tree Cover) layers also became available in finer resolution as compared with the previous version. ISCGM has started working closely with the United Nations Committee of Experts on Global Geospatial Information Management trying to reflect international needs for developing reliable geospatial information.
