Summary

The magnetic field generated in the Earth’s lithosphere carries information on the Earth history and tectonics. It is therefore worthwhile studying, but gathering magnetic data for this purpose is a task requiring time and significant ressources. This has been the main objective of the World Digital Magnetic Anomaly Map (WDMAM) project. We recall here the main steps that led to the first and second versions of the map. We further discuss the models that have been derived from the map, and finally describe recent works to interpret these models in term of magnetisation of the crust. We see these recent developments as major steps forward for an efficient exploitation of the magnetic data collected near the surface of the Earth.
