Global Mapping project is an endeavor advocated by the Ministry of Construction (present Ministry of Land, Infrastructure and Transport) in 1992 to develop a digital map (Global Map) covering the whole globe to accurately express the status of global environment, implemented in international cooperation of respective National Geospatial Information Authorities (NGIAs) of the world. The Global Map can be used for studying global environmental problems, etc.
The Global Map data development is underway steered by the International Steering Committee for Global Mapping (ISCGM). The Geospatial Information Authority of Japan (GSI) serves as the ISCGM Secretariat which takes a central role of the project management. The GSI also provides developing countries with necessary technologies.
