Analysis of geological structures provides important information on the thicknesses, declivities, and volumes of rock removed, for example. In this paper, an alternative method of calculating approximate thicknesses and volumes of geological structures is presented through the use of smartphones and satellite technology. The method consists in taking photographs with digital wireless devices of the wall of the geological structure to study from a known position and distance. Through a program of analysis of images, photographs were dimensionally calibrated and digitally processed to get better detail. Moreover, via the applications of smartphones (Global Positioning System (GPS)), the work areas were located at GoogleTM Earth to determine their surface area, which was calculated with the transfer of images to AutoCAD software. The determination of the thickness and volume of rock and material extracted with the methodology proposed here, show simple forms of work and quite accurate, which would otherwise be extremely complex for determination.
