Description

There are random errors in every survey measurement, but how do surveyors manage and account for them? It all starts with understanding the sources and magnitude of those errors. Once armed with that information, surveyors can logically analyze the quality of each individual measurement and the resulting impact of those errors on the overall survey. Surveyors also expend a lot of time avoiding blunders and analyzing and accounting for random errors in their measurements. Yet the effect of random errors on a boundary determination is minuscule compared to the potential uncertainties in a boundary associated with field or record evidence of questionable lineage. As the 2016 ALTA/NSPS Standards say, "...a boundary corner or line may have a small Relative Positional Precision because the survey measurements were precise, yet still be in the wrong position (i.e. inaccurate) if it was established or retraced using faulty or improper application of boundary law principles." So, in this course, in addition to providing background and details related to the issue of measurement uncertainty on ALTA/NSPS Land Title Surveys, we will also explore the uncertainties that can impact the integrity of a boundary survey that are not related to measurements - and that are often the answer to the question "Why can't two surveyors ever agree?!"

Objectives

Random error sources

Describe the primary sources of random error in survey measurements

Measurement analysis

Explain how to analyze survey measurements and assess the magnitude of the random errors

Uncertainty calculations

Calculate the allowable measurement uncertainty on an ALTA/NSPS Land Title Survey

Interpret analysis results

Interpret the results of an analysis of the measurements on an ALTA/NSPS Land Title Survey with respect to the allowable measurement uncertainty

Achieving allowable RPP

Design an ALTA/NSPS Land Title Survey that will result in measurements that do not exceed the allowable relative positional precision

Non-measurement-related uncertainty

Outline the three sources of non-measurement related uncertainty in boundary locations

Effectively communicating information about uncertainties

Explain how to effectively communicate important information about the uncertainties in boundary location to clients, attorneys and other surveyors

Measurement uncertainty vs. non-measurement uncertainty

Describe the difference between measurement uncertainty and non-measurement uncertainty on a survey
