With the aid of a simple theoretical model, of an insulating sphere in a homogeneous conducting medium, this note discusses the relative merits of ‘longitudinal’ and ‘transverse’ passages of earth resistivity arrays over buried features. It is shown that pseudo‐sections developed from the transverse passage of Wenner and twin‐probe arrays are significantly less ambiguous than for longitudinal traverses. The practical significance of this difference in the realization of ‘true’ vertical sections is discussed briefly. © 1997 John Wiley & Sons, Ltd.
