AEROMAG 1992-2013: magnetic map

The total magnetic intensity map from the AEROMAG 1992-2013 project is generated by merging grids of separately processed datasets with the grid knitting module of the software Oasis Montaj. The crustal magnetic field model MF7 https://geomag.colorado.edu/magnetic-field-model-mf7.html is used as a regional reference grid when merging the datasets. The magnetic anomaly map is IGRF corrected, but is not reduced-to-the-pole. The grid sampling is 100 x 100 m and the used coordinate system is WGS 84 / UTM zone 22N. The grid of the total magnetic anomaly map is provided in the following formats: (1) GeoTIFF Color (*.tif) (2) Geosoft Color Grid (*grd) (3) ArcView BinaryRaster grid (*flt) (4) xy ASCII data (*.xyz) In addition, presented images of AEROMAG maps on the Greenland Portal are provided as GeoTiff files.
