TellusSW airborne geophysics. Magnetic data.Derived Horizontal Gradient of the PseudoGravity of the Total Magnetic Intensity (TMI) anomaly field.

The map covers the airborne geophysical survey area of SW England. The map uses a grid cell resolution of 40x40 m.

The map shows the derived Horizontal Gradient of the PseudoGravity of the Total Magnetic Intensity (TMI) anomaly field. The colour scheme is based on an equal-area scheme such that each colour occupies an equal area on the map. Shaded relief from the NE. Further information is available from the TellusSW resource page.
