Gravity anomaly maps (see globe below) show how much the Earth’s actual gravity field differs from the gravity field of a uniform, featureless Earth surface. The anomalies highlight variations in the strength of the gravitational force over the surface of the Earth.

An outstanding example is the Bouguer gravity map of the United States published in 1982 by the Society of Exploration Geophysicists.
