Taquimetría: Is the topographic technique that employing the instrument called a tachometer, manages to make a topographic or graphic representation of a field, without considering the curvature of the Earth. Also as a system that allows to determine the position of a characteristic Xpunto or fill in a Lesvantamiento, referring to a special item called station, through the measurement of its polar coordinates and its gap with that point is defined. This special is that is determined by the intersection of the vertical axis and the axis the tachometer centered on a point fixed or estacado in field forizzontal.
