FIG. G-7. Corrections to gravity data and the names of the resulting anomalies. The terrain correction is not always applied to free-air data. Eötvös corrections also have to be made if the meter was moving during the measurement[1].

(boo ger’ or bo gar’) 1. The value obtained after latitude correction, [[Special:MyLanguage/Dictionary:elevation correction |elevation correction]] (including both free-air and Bouguer corrections), Eötvös correction (for marine and aerogravity), and (usually) [[Special:MyLanguage/Dictionary:terrain correction |terrain correction]] have been applied to gravity data. If a terrain correction has not been made, the result is sometimes called simple Bouguer. The Bouguer gravity field is not the same as the field that would have been observed at the datum elevation, because the shape of anomalies resulting from remaining density irregularities still are appropriate to the elevation of measurement rather than to those of the datum elevation. Also called Bouguer gravity.

2. A veces se presenta una desviación en la suavidad en los contornos en un mapa que muestra los valores de Bouguer (es decir, un residual en los valores de anomalía de Bouguer). Nombrado para Pierre Bouguer (1698–1758),(1698–1758), matemático francés que intentó determinar la figura de la tierra. Véase Chapin (1996) y Figura G-7.
