Least Squares and Positional Tolerance

MALSCE Webinar Series

Least Squares and Positional Tolerance

Thursday, April 22, 2021
12:00 PM - 1:00 PM EDT
Zoom Video Webinar*

The use of least squares is often a difficult subject in much of the surveying world because it uses math that we are not familiar with, or it is math we stared at long ago in a surveying class and worked hard to forget.  We need to become comfortable with its use and learn that it can enhance our abilities in surveying.  The seminar will start with real total station data and how it is simple to analyze a least squares report.  Next GNSS network adjustment results will be examined.  The least squares component of the 2021 ALTA/NSPS standards will next be examined as a standard most surveyors at some point need to deal with.  The concepts of relative vs. absolute error ellipses and how 95% confidence is achieved will be themes throughout the discussion using the ALTA standard as an example.  Suggestions for passing such standards will be presented.  The seminar is very question/answer oriented. 

*    Zoom Video Webinars is a widely used webinar platform. You will hear the voice of the speaker and watch a PowerPoint and live software presentation. This technology allows for questions and answers. Webinar login information will be sent to registrants the week of the webinar.

Speaker

Raymond J. Hintz, PLS, PhD, Professor, University of Maine

Raymond J. Hintz is a professor of surveying engineering technology at the University of Maine, program coordinator for the B.S. program in surveying engineering technology and graduate coordinator for the Professional Science Masters in Engineering and Business surveying engineering concentration. His research interests lie in automation of data collection and processing of surveying and photogrammetric information. Dr. Hintz has published more than 50 articles in journal and conference proceedings related to surveying, and is a registered land surveyor in the states of Maine and Florida. He is active in promoting UAS technology, with a portion of two Photogrammetry courses he teaches dedicated to surveying and mapping using UAV technology. He also conducted nine one-day seminars to various organizations on UAV’s in the last two years. In addition to his academic experience, Dr. Hintz is recognized for his role in developing several software packages including the Cadastral Electronic Field Book (CEFB), Cadastral Measurement Management (CMM) and Geographic Measurement Management (GMM). The CEFB enables automatic entry of measurement and automated field note information into CMM, a computation tool for survey and analysis of cadastral surveys. GMM was adopted as the approved tool for development of the Bureau of Land Management’s Geographic Coordinate Data Base.
