A quick look at the science and theory of surveying measurements
Friday, January 10, 2025
1:00 p.m. - 2:50 p.m.
Surveying is many things. But included in the top 5 things that surveyors are known for by the general public, is the ability to make quality measurements with a much higher degree of refinement than those who are not surveyors. What then is the expectation? And more importantly, how do we achieve it? Seldom do schools, on-the-job training and bosses tell us how to do it and why. In this course, you will learn how to take the care that is needed to ensure that what your clients expect is what they get.
In this course, some of your takeaways include:
*Analyzing your specific situation to determine how (and with what) you should measure
*Understand what the manufacturers of your instrumentation really mean when they state accuracy
*Have an understanding of surveying measurement so that you can explain to your client or a lawyer or a judge,
what it is you did, and why it is appropriate.
Some of the topics include:
*The nature and types of errors and how to include this understanding in your planning
*Executing and analyzing fieldwork
*Mistakes (blunders) and avoidance
*Adjustment of errors
*Weighting
*Standard deviation, confidence intervals, standard deviation of the mean
*Most probable values
*Evaluating performance levels of surveying systems
*Applying results of evaluations to survey practice
Depending on length of seminar and requirements of seminar attendees, topics can include: nomenclature; hands-on demonstrations using instrumentation of the students, with discussion on practical application of the results; angle-distance equivalents; discussions of traverse and other adjustments and the assumptions made; significant digits when calculating and reporting distances, directions and areas; trigonometric leveling; traversing with GPS.
