Since 1977 the International Association of Geomagnetism and Aeronomy (IAGA ) has invited its member organizations to provide magnetic anomaly maps and data for a World scale compilation.
Much workhas beendone on this basis, untilIUGG/IAGA 2003 in Sapporo, whereWDMAM task force was established by IAGA working group V-MOD toprepare plans tocomplete the work. Minutes of WDMAM at Sapporo
Atthe General Assembly 2004 in Florence Commission of the Geological Map of the World (CGMW )initiated co-operation of compilation.
AttheGeneral Assembly 2006 of CGMWin Parisa tentative map was presented and a resolution was given to contribute.
Working groupto produceWorld Digital Magnetic Anomaly Map (WDMAM) was established at IAGA 2005 in Toulouse. It invites all interestested to take part.

Invitation by WDMAM
WDMAM invites all organizations and scientists to submit magnetic anomaly data, provide methods, and compile a draft magnetic anomaly map.
