# Computer Programs for Strip Aerotriangulation

*A FORTRAN IV computer program was developed for each of the following three methods of strip aerotriangulation: (1) fully-analytical; (2) instrumental; and (3) semianalytical, by independent...*

Buckling of Rigidly-Jointed Plane Trusses

*A direct method for determining the critical loading pattern of a rigidly jointed truss as a whole is presented. It was found that the equation of the critical load is independent of the...*

Geodesy and Photogrammetry in the 1960's

*The basic geodetic control network in the United States includes about 100,000 monumented first- and second-order horizontal control stations that are accurately related one to another,...*

Survey Control for Concrete Dam Construction

*The development of survey controls for Morrow Point Dam, a double-curvature, concrete-arch structure, 465 ft in height, was required through the phases of reconnaissance, site investigation,...*

Electronic Traverse Versus Triangulation

*The USC & GS in its concern over the costs of long-range, highly accurate geodetic surveys, conducted extensive tests comparing electronic traverses, using Tellurometers with triangulation....*

Snap-Through Buckling of Framed Triangulated Domes

*The elastic stability problems that develop when a concentrated load is applied to a frictionless joint of a framed triangulated dome were studied. They were found to be of two types:...*

Double Summation of Errors in Aerial Triangulation

*Data from a 100-model grid triangulation are used to demonstrate certain features associated with the double summation of errors in the transfer of scale, azimuth, and longitudinal tilt...*

Aerial Triangulation Using Independent Photo Paris

*Three different methods of determining control points with second-order photogrammetric instruments have been examined. The practical uses of these methods are illustrated and analyzed....*

Analogue Aerial Triangulation

*Analogue aerial triangulation procedures for application on the precision photogrammetric plotting machinery are dealt with in a simple way, and the mathematical basis of the procedures...*

Simultaneous Relative Orientation of Multiple Cameras

*There are two groups of solutions to the problem of analytical aerotriangulation. The first group uses a cantilever extension technique based on independent triangulation of two-photograph...*

Measuring Structural Behavior of Glen Canyon Dam

*This paper describes layouts of two systems and the methods used for measuring the deformation of Glen Canyon Dam, a large, concrete, arch structure. The deformation is caused by water...*

Cadastral Surveying in Alaska

*New methods are being used to facilitate the task of surveying public lands in Alaska. These methods include the computation of positions of corner monuments so they can be positioned...*

Strength of Figure Equation in Triangulation

*That which is termed strength of figure equation is a basic tool for analyzing a triangulation scheme in geodetic surveying. The derivation of this equation is not readily available (as...*

Aerial Traverse and Maximum Bridging Distance

*Aerial triangulation methods, a major problem in photogrammetry, require the use of first-order instruments. A method for using second-order instruments, which offers two solutionsâ€”numerical...*
