Description
The World Digital Magnetic Anomaly Map project is an international effort to integrate all available near-surface and satellite magnetic anomaly data into a global map. Teams of researchers were invited to produce candidate maps using a common pool of data sets. This contribution is version 1.1 of the NGDC candidate, both as a grid and a map in PDF format. The official World Digital Magnetic Anomaly Map is expected to be released in July 2007 and will be available in print and on digital media from the Commission for the Geological Map of the World, 77, rue Claude-Bernard, 75005 Paris, France.

June 2009 update
