Analysis of Observations KGG370



Observations of many different types are central to the determination of information across the geospatial sciences. In this unit, students will gain knowledge in the theory and practical application of least squares adjustment techniques including the reduction of raw measurements; weighted adjustment of observations; detection of outliers; parameter uncertainty; network design and optimisation of observations.
The unit focuses on providing students with an appreciation of uncertainty and how it is treated and communicated within the land surveying profession. Students are introduced to a range of advanced adjustment concepts
Case studies are used to provide practical application of the material presented in the interactive lectures. Tutorial exercises provide students learning opportunities that include the use of different computational and adjustment packages used across industry.
The unit brings together the analysis of different observation types that students have used in KGG255 Surveying 1 and KGG220 Surveying 2 and extends to provide examples relevant to KGG306 GNSS: Global Navigation Satellite Systems and KGG307 Geodesy: Observing Our Changing Planet.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.
