Web3 jun. 2015 · I am trying to understand how a surveying total station calculates new point locations based on it's measured location, the 3d (slope) distance that it measures to a new point, and the measured horizontal and vertical angles that sight onto the new point location. Thanks, E WebFigure 1. Fundamental measurements made by a Total Station: horizontal angle, vertical angle, and slope distance. All other values returned by the total station are derived from these measurements. Horizontal Angle The horizontal angle is measured from the zero direction on the horizontal scale (or horizontal circle).
