Union Pacific has turned to aerial topography and inertial surveying for the location of a proposed line in Wyoming. The 37-mile alignment was through a territory with few reference points. The inertial survey device with its gyroscope and accelerometers can be transported by helicopter or land vehicle to produce three-dimensional coordinates and maps accurate to 1 in 20,000. The computer-processed results are automatically transformed into complete maps.
