Mike Purucker and Terry Sabaka of Raytheon at the Planetary Geodynamics Lab are providing important contributions to the development of a World Digital Magnetic Anomaly Map (WDMAM). The project, scheduled for public unveiling in 2007, will produce a map that will outline quasi-static magnetic sources in the earth's upper lithosphere at an unprecedented level of detail (5 km grid). This will be accomplished by combining surface, aircraft and spacecraft data
At a recent meeting in Toulouse, France, a consensus was reached on how the map will be produced and evaluated and the first preliminary global maps were exhibited at a companion scientific session (see the map by Purucker, below). The WDMAM will be published by the Commission for the Geological Map of the World (CGMW), will use the same projections and scales as the Geological Map of the World, and should significantly enhance our understanding of global geology and crustal structure.
