Control Survey: Lambert Projection correct answer: An imaginary cone is placed around the earth so that the apex of the cone is on the earth's axis of rotation above the North Pole, for northern hemisphere and below the South Pole for southern hemisphere projections. East west direction is relatively free from distortion in this method. Therefore, states longer in east-west direction are projected with this system, Scale is set for 158 miles of N/S distance in this method. Transverse Merc...
