    • Surface and Underground Geodetic Control for Superconducting Super Collider 

      Gregory L. Robinson; W. J. Trevor Greening; Peter W. DeKrom; Adam Chrzanowski; Edward C. Silver; Gary C. Allen; Mike Falk (American Society of Civil Engineers, 1995)
      Stringent accuracy specifications required that particular care be taken in the provision of geodetic control for the construction of the Superconducting Super Collider. The design and implementation of the surface geodetic ...
    • Intersection of Spiral Curve with Circle 

      Olcay Öztan; Orhan Baykal; Oguz Müftüoglu; Muhammed Sahin (American Society of Civil Engineers, 1995)
      This study examines the problem of the intersection of a spiral curve with a circle, which especially occurs in the design of junctions. To achieve the requirements, an iterative method which has been programmed, is suggested ...
    • Determination of Look Angles to Geostationary Communication Satellites 

      Tomás Soler; David W. Eisemann (American Society of Civil Engineers, 1994)
      Basic geodetic theory is applied to determine the geodetic azimuth and geodetic altitude required to point dish antennas to geostationary communication satellites. The mathematical treatment presented here takes into ...
    • Survey Distance Units: A Better Way 

      Larry E. Stanfel (American Society of Civil Engineers, 1994)
      The conventional units of surveying distance, the chain and the link, have been in use for about 200 years. Yet, for an important class of survey operations, halving distances, the units become fractional after very few ...
    • Developing a National Spatial Data Infrastructure 

      John McLaughlin; Sue Nichols (American Society of Civil Engineers, 1994)
      The present paper briefly reviews the findings of a recent U.S. National Academy of Sciences report on the proposed development of a national spatial data infrastructure that will be the foundation for the evolving spatial ...
    • Reviewers of the <i>Journal of Surveying Engineering</i> 

      Unknown author (American Society of Civil Engineers, 1994)
    • Kinematic Ambiguity Resolution with High‐Precision C/A Code Receiver 

      M. E. Cannon; G. Lachapelle; G. Lu (American Society of Civil Engineers, 1993)
      On‐the‐fly resolution of carrier phase ambiguities, which is the key to centimeter‐level accuracy in differential kinematic GPS positioning, is investigated using a high‐precision, single‐frequency, 10‐channel, C/A code ...
    • Bandwidth in Joint Adjustment of Geodetic Networks Having Common Points 

      Olcay Öztan; Yunus Kalkan; Zafer Kizilsu; Ufuk Özerman (American Society of Civil Engineers, 1994)
      In this paper, a formula is presented for obtaining the bandwidth that would allow the inclusion of the normal equation coefficients differing from zero into the band, which are derived during the adjustment of several ...
    • Optimization of Horizontal Direction Observations in Triangulation or Triangulateration Networks 

      Shanlong Kuang (American Society of Civil Engineers, 1993)
      This paper deals with the modeling and solution of an optimal direction observation scheme in two‐dimensional triangulation or triangulateration networks under a given precision criterion matrix of the estimated coordinates. ...
    • Simple Numerical Method for Solving Horizontal Circular Curves 

      Said M. Easa (American Society of Civil Engineers, 1994)
      When the radius and deflection angle of a horizontal circular curve are given, the other five curve elements can be directly computed. The elements include tangent distance, external distance, middle ordinate, length of ...
    • Optimal Location of Extra Gyroscopic Azimuth in Underground Traverses 

      Janusz Martusewicz (American Society of Civil Engineers, 1993)
      In traditional underground surveying operations, where a bearing is transferred through a single shaft, only one azimuth of the underground traverse is involved. The use of gyroscopic measuring equipment, however, allows ...
    • Editorial 

      Earl F. Burkholder (American Society of Civil Engineers, 1994)
    • Blunder Detection and Data Snooping in LS and Robust Adjustments 

      Charles R. Schwarz; Johan J. Kok (American Society of Civil Engineers, 1993)
      There are many procedures for adjusting data and detecting the presence of blunders in a set of observations. Most such procedures involve examining the adjustment results for residuals whose magnitude is in some sense ...
    • Guest Editorial 

      James P. Weidener (American Society of Civil Engineers, 1994)
    • Survey and Alignment of Particle Accelerators and Transport Lines 

      Robert E. Ruland (American Society of Civil Engineers, 1994)
      The present paper summarizes the survey and alignment processes of accelerators and transport lines and discusses the propagation of errors associated with these processes. The major geodetic principles governing the survey ...
    • Quality Control with Reliability for Large GPS Networks 

      Alfred Leick; Michael B. Emmons (American Society of Civil Engineers, 1994)
      The Orange County GPS survey comprises more than 7,000 vectors linking more than 2,000 stations. The observations were made by private firms and the County of Orange Survey Division staff. Several functions are identified ...
    • ASCE Proposed Model Standard of Practice for Property Boundary Surveys 

      Unknown author (American Society of Civil Engineers, 1993)
      This proposed standard is suggested as a model for adoption by local bodies of surveyors and engineers who practice land surveying. Besides expounding and clarifying certain often‐ignored surveying principles, it recognizes ...
    • Use of Laser Targeting in Precise Machinery Surveys 

      W. F. Teskey; D. A. Bayly; H. E. Martell (American Society of Civil Engineers, 1993)
      Precise machinery surveys, incorporating laser targeting, can now be carried out in near real time using an electronic theodolite system. Within the Industrial Alignment Project, a cooperative research and development ...
