Abstract

"The first thought of establishing a triangulation system for the University of Arizona student work was conceived early in the fall of 1947, when the author first learned that he would be in charge of the advanced surveying field parties during the spring semester. These men were to be instructed in the accepted manner of conducting surveys of higher order. This would include the measuring of a base line of second or first order accuracy, the turning of horizontal angles with this same degree of accuracy, the determination of the azimuth of the lines by astronomical observations, the running of a second order line of levels for elevation determination, and the computation and correlation of the resulting data...After due consideration, an area west of Tucson known as the Tucson Mountain Park was chosen...The following discussion will deal with the methods used in conducting this particular triangulation survey. Included in the discussion, will be the reconnaissance work dealing with the selection of suitable locations for the base line and triangulation stations, together with the design of the signal towers used on each triangulation station. A description of the tests made for color selection of the best visibility will be included along with colored photographs of the signal towers. The methods used in turning the horizontal angles will be covered along with the type of instruments used. Some time will be spent on elevation control, using trigometric leveling and spirit leveling of second order accuracy. Computations will be made for distance, elevation, azimuth, latitude, longitude, and plane coordinates. The computations involving the angles and distances will be adjusted by the least squares method as practiced by the Coast and Geodetic Survey"--Introduction, page 1-3.
