Course Overview
This course starts with the theory of geomatics observational errors; measures of precision and accuracy; propagation law of errors; weights and propagation of weights; statistical distributions; statistical hypothesis-testing (significance level, power of test, type I and type II errors); and confidence region estimation. It introduces the concept of least-squares adjustment and its applications, including the use of commercial least-squares adjustment software packages to perform least-squares adjustments, pre- and post-adjustment analyses, and design of survey schemes and specifications. Students learn through lectures, assignments, and labs. Co-requisites: GEOM 4060 Engineering Surveys; GEOM 4010 Field Survey Capstone

Learning Outcomes
Upon successful completion of this course, the student will be able to:
- Explain the theory of errors, precisions, accuracy, and weights of geospatial measurements.
- Apply the error and variance-covariance propagation laws to geomatics measurements.
- Relate the concepts of estimation, probability, hypothesis-testing, and statistics.
- Use statistical methods (confidence interval estimation and hypothesis-testing) to assess the magnitudes of errors in the means of surveying measurements (including the means and variances).
- Discuss criterion, concept, advantages, disadvantages, and applications of least-squares adjustment.
- Apply the principle of least-squares adjustment to adjust simple survey network measurements.
- Solve practical geomatics problems using a commercial least-squares adjustment package.
- Design and analyze survey schemes and specifications by computer simulation.
- Perform post-adjustment global and local tests to detect outliers in measurements and evaluate quality of adjustment computations.
