... greatly re- duced by adaptive random down-sampling of the soundings. GROUND TEM Except for the surveys using a small moving loop, the spa- tial layout of ground survey can be more complicated: (1) the transmitter loop is much larger than a magnetic dipole and can be arbitrarily shaped; (2) one transmitter...
