Um exemplo da utilização de gradiente transversal medido no aumento da resolução de imagens aeromagnéticas em baixas latitudes magnéticas

The present work was designed to evaluate if it is possible to observe an increase on the resolution of airborne magnetometry images when using measured lateral gradient during interpolation of total magnetic field data. Images were enhanced using pseudo-line method. The used sample dataset was collected at low magnetic latitudes, specifically in the Brazilian territory. The result for the specific dataset was clear, the enhanced image has a resolution much superior than the original image. Furthermore, its resolution can be compared with a resolution of a single sensor survey with half of line spacing of the original gradiometer survey.
