  • OPUS-RS Pair Points: Case Study

    • Journal of Surveying Engineering (ASCE), Vol. 136 No. 2
    • May 2010
    Authors: Peter Lazio

    Referencing small engineering surveys to the national spatial reference system (NSRS)presents advantages in terms of spatially coordinating infrastructure and facilitates the inclusion of the infrastructure in a geographic information system. In cases where the total station is the appropriate tool to conduct the survey, online positioning user service rapid static (OPUS-RS) can be employed to economically establish azimuth pair points to orient the survey to the NSRS. Using OPUS-RS coordinates as observations along with global positioning system (GPS) vectors and total station observations in a least-squares adjustment to establish the azimuth pair points adds robustness to the least-squares adjustment to isolate systematic errors. All the observations contribute to the least-squares adjustment but some observations contribute more than others do. Redundancy numbers can be used to identify those observations that contribute little to the adjustment results. By analyzing the results of three least-squares adjustments, it will be shown that under normal conditions total station observations contribute little to the overall adjustment. Under obstructed conditions total station observations contribute to the vertical precision of the azimuth pair points. OPUS-RS appears to be less susceptible to vertical biases than GPS vectors at obstructed sites.

  • Constraining Network Adjustments to OPUS-RS Coordinate Observations

    • Journal of Surveying Engineering (ASCE), Vol. 133, No. 3
    • August 2007
    Authors: Peter Lazio

    OPUS rapid static (OPUS-RS) was introduced to the public in August 2005 as an operational prototype. Allowing centimeter accuracy with 10-15-min observation sessions, OPUS-RS holds the promise of dramatically lessening the time needed to reference a survey to the National Spatial Reference System. (NSRS). The purpose of this paper is to compare results between networks constrained to the NSRS using multiple short OPUS-RS observation sessions and much longer OPUS observation sessions. The results of this comparison demonstrate that multiple short OPUS-RS sessions provide for significant time savings with results that agree within a centimeter of the longer OPUS sessions.

  • OPUS Observations

    • Surveying and Land Information Science (ACSM), Vol. 66 No. 3
    • September 2006
    Authors: Peter Lazio

    Although primarily a positioning service, the coordinate values provided by the National Geodetic Survey’s On Line Positioning User Service (OPUS) may also be used as observations in a least squares adjustment. This is made possible by the inclusion of the coordinate covariance matrix in the OPUS extended data report. A covariance matrix is one of the necessary components in a least squares adjustment. We will develop the other necessary component for a least squares adjustment, namely, the mathematical model, and demonstrate how commercial least squares adjustment software can be used to incorporate OPUS in a network adjustment. OPUS vectors and coordinates can be used as observations to rigorously combine multiple OPUS solutions for the same station and or they can be combined with other measurement methods in a network adjustment.

  • Advancement through Consolidation (Guest Editorial)

    • Journal of Surveying Engineering (ASCE), Vol. 132 No. 4
    • November 2006
    Authors: Peter Lazio

    The common goal of the convergence of these disparate technologies is to move surveying away from a measurement-oriented profession to a data-centric profession. As sophisticated, multitechnology tools allow the acquisition of more information, the surveyor’s role is increasingly developing to organize and direct the flow of that data. Understanding how the surveyor’s data contribute to the success of the enterprise is the indicator by which the professionalism of the surveyor will be measured in this new surveying environment.

  • GPS Geodesy and Applications (GPS-GAP) - An Internet Based Geodesy and GPS Educational Application

    • Surveying and Land Information Systems (ACSM) Vol. 65 No. 2
    • June 2005
    Authors: Peter Lazio

    Advances in GPS have outpaced the training infrastructure. To fill this void, surveyors are attending seminars or manufacturer-sponsored training courses. The courses do a satisfactory job at presenting fundamental concepts and foster basic proficiency with the particular manufacturer’s receivers and software. Seminars, on the other hand, present no more than a general overview of theory. Sound theoretical principles cannot be taught in the short period of time allocated to either form of instruction. A detailed, mathematically based course of study is not possible via training courses or seminars: mainly because of time limitations, the mathematics powering the black box is either overly simplified or ignored. The University of Maine sponsors an Internet-based program—GPS Geodesy and Application Program (GPS-GAP) which fills the need for mathematically rigorous courses of instruction for surveyors using GPS and other geodetic applications.
