19 lip 2024 · EMAG2 is a global map of magnetic anomalies derived from satellite, ship, and airborne data. It is used for resource exploration, navigation, and studying the lithosphere evolution. Download or access EMAG2 v3 data, maps, and metadata.
6 lip 2015 · EMAG2 is a map of the Earth's magnetic field anomalies, compiled from various sources and available in different formats. It shows the subsurface structure and composition of the crust, and can be used for geological and resource exploration.
EMAG2 is a grid of magnetic anomalies that reveals the subsurface structure and composition of the Earth's crust. Explore EMAG2 on a 3D virtual globe with different colour schemes and data sets.
1 sty 2009 · EMAG2 is a significant update of our previous candidate grid for the World Digital Magnetic Anomaly Map. The resolution has been improved from 3 arc min to 2 arc min, and the altitude has been reduced from 5 km to 4 km above the geoid.
30 lis 2017 · In EMAG2, a directional gridding algorithm was used, with larger correlation lengths along isochrons as given by an oceanic crustal age model (Müller et al., 2008). In the first WDMAM, gaps were directly filled with synthetic magnetic anomalies derived from an oceanic crustal age model.
EMAG2 is a 2-arc min resolution grid of magnetic anomalies derived from satellite, airborne, and marine measurements. It is a significant update of the World Digital Magnetic Anomaly Map and available at http://geomag.org/models/EMAG2.
