Least Squares and Positional Tolerance

Approved for 1.0 NY LS/PE CE Hour

Least squares has become a standard option in surveying measurement processing due to computerization. Slowly, use of the potential of post-adjustment coordinate error estimation has entered surveying analysis. How least squares is used in positional tolerance analysis will be presented via live display of processing of survey data.


Seminar Goals and Objectives

  1. Explain least squares input and output in surveying
  2. Describe post adjustment coordinate error analysis
  3. Explain how a positional tolerance test can work

About our Speaker

Raymond J. Hintz is a professor of surveying engineering technology at the University of Maine, and is program coordinator for the B.S. program in surveying engineering technology. Prior to his present position from 1983-1987 he was an assistant professor of civil engineering at the University of Florida. He has B.S., M.S., and PhD degrees in Civil and Environmental Engineering with emphasis in surveying and photogrammetry from the University of Wisconsin. His research interests lie in automation of data collection and processing of surveying and photogrammetric information. Specific to the topic of interest, he has been responsible for development of the Cadastral Electronic Field Book (CMM). At the heart of CMM is a least squares analysis driver fro conventional survey measurements and GPS. Both products were developed for the Bureau of Land Management. Also in conjunction with the Bureau of Land Management, he has developed Geographic Measurement Management, which is the approved tool for development of their Geographic Coordinate Data Base. GMM has a least squares analysis system which is designed for record survey information. A third project was partial responsibility for he development of Florida Department of Transportation's Electronic Field Book, data processing, and topographic data modeling software system. His primary involvement in this project was the Electronic Field Book Processer (EFBP) which is the least squares analysis engine for an automated link from raw data to final coordinates. EFBP has in recent times been adapted to also accept SDMS (AASHTO) format data and various vendor raw survey data formats. He has published more than 50 articles in journal and conference proceedings, and is a registered land surveyor in the states of Maine and Florida.
