Rationale
A reference framework for the attachment of spatial data and information is essential for most Surveying operations. Frameworks exist at global, regional and local scales as Survey Control Networks and form part of our national infrastructure. Different networks may contain different information for one, two and three dimensional use and beyond local scales the true shape of the Earth must be considered. This unit focuses on the contributions of spatial measurements (non space-based) to the creation of networks, assessment of networks and extension of networks. Space based technologies are considered in the Geodesy unit for which this unit is a prerequisite.
Aims
This unit aims to provide students the comprehensive skills to be able to establish, assess, utilize and classify survey control networks.
Objectives
By the completion of this unit you should be able to:
- Work independently on a range of computations using a reference spheroid.
- Formulate, process and assess one, two and three-dimensional networks with respect to its sensitivity to undetected errors and produce least squares estimates for means and precisions.
- Demonstrate skills to test, assess and calibrate relevant surveying measurement instrumentation.
- Engage as part of a fieldwork team to determine height differences using both precise levelling and trigonometric techniques.
- Engage as part of a fieldwork team to interpret specifications to design and establish new, high precision survey control within an existing network and classify network outcomes.
Content
- Spheroid Computations involving associated geodetic reference frames.
- Calculation skills for determining accurate geodetic positions, azimuths and distances on the ellipsoid.
- Forward and reverse problems involving coordinate transformations between reference frames.
- Functional and stochastic modelling of survey measurements including observation equations and a-priori information.
- Least Squares adjustment applied to one, two and three dimensional measurement problems.
- Precise levelling techniques, systematic testing, applications and data analysis.
- Theory and practice associated with calibration of electronic distance measuring instruments.
- Specifications and recommended field practices for establishing traditional survey control networks.
- Technical reporting and classification of survey control information.
Approaches to Teaching and Learning
You will explore the theoretical concepts that underpin the survey measurement methods in this unit through lectures and develop key analysis skills through real-world problem solving. Tutorials will utilize real-world examples providing challenges and alternative problem solving strategies. You will undertake field survey work to develop understanding and competency in applied field-survey measurements. This will also involve experiential learning approaches. Analysis and adjustment of survey measurements will predominantly use software approaches.

Academic Honesty
QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.
A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.

Risk assessment statement
Students will be required to have completed a construction site safety course (blue card) prior to engaging in the necessary off-campus fieldwork. Workplace Health and Safety requirements relevant to this unit relate particularly to fieldwork. A risk assessment for the off-campus fieldwork has identified several low impact risks including travel, slips and trips, animal bites, and animal and plant stings. You will be provided with safety guidelines prior to each trip. In addition, the faculty provides a health and safety manual detailing health, safety and emergency procedures for you to read and put into practice. We therefore require student to understand and obey all safety guidelines. Briefing sessions will be given at the beginning of each field day.
The QUT Student Rules, Policies and Procedures apply in this unit.
