Commission for the Geological Map of the World (CGMW)
The CGMW, the oldest international organisation in geoscience after the International Geological Congress (IGC), was created in 1881. It promotes, co-ordinates and publishes small-scale Earth sciences maps of continental regional areas of the World, including oceans. Many CGMW maps are published jointly with UNESCO.
The CGMW is organized into a number of different sub-commissions along geographic (one per continent or sub-continent) and thematic lines. CGMW's General Assemblies are held every two years, alternatively at UNESCO Headquarters in Paris, and within the framework of the International Geological Congress. These meetings are an occasion to examine the outcome of current cartographic projects and to define the trends of future programmes.
