Global Mapping Project, launched in 1996, is an international cooperation initiative through voluntary participation of national mapping organizations in the world, and led by the International Steering Committee for Global Mapping (ISCGM) and its Secretariat, c/o Geospatial Information Authority of Japan (GSI).
Global Map aims to develop a digital geo-information framework ensuring spatial resolution at 1 km, with standardized specifications and available to everyone at marginal cost.
Global Map datasets consist of 8 basic layers (Boundaries, Drainage, Transportation, Population Centres, Elevation, Land Cover, Land Use, and Vegetation) for currently 71 countries and 4 regions, collectively covering 60% of the whole land area. Global Map (global version) for elevation, land cover and vegetation (percent tree cover) layers wholly covers the land area of the globe.
