Terrain, g , computed using a digital terrain model derived by combining terrain from several sources. Within the survey area,the line data were used to calculate the topography bysubtracting the altimeter data from the altitude of the aircraft above the mean sea level. Terrain data for the area outside the survey blocks were derived by combining 3 arc secondCanadian Digital Elevation Data and 30 arc second USGS

Thus Bouguer anomaly = G - g - g - g + g - g - g , where G is the calculated gravity adjusted for Eötvös effect andnormal gravity.
