A line of gravity readings taken over a topographic feature having appreciable relief that is not associated with density variations or structure, the object being to determine the best density factor for elevation corrections; Nettleton’s method. The most appropriate density is the one that minimizes the correlation of gravity values with elevation. Method devised by L. L. Nettleton. See triplets and Telford et al. (1990, 18).
