Unit Outline

This is the second in a series of units developing competencies in applying survey instruments, field techniques and computational analyses to measure and solve geometric problems in natural and built environments. In this unit, you will gain a deeper understanding of measurement science and develop their ability to discern the appropriate application of precise survey methodologies for a range of real-world circumstances. This semester, you will expand on the practical instrumental and methodological skills introduced in the fundamentals of surveying unit. Precise levelling and electronic total stations will be used in practical classes to undertake surveys and implement advanced techniques to achieve a high level of precision in the resulting spatial data. Survey methodologies, instrument calibration and advanced computational analysis for precise levelling, trigonometric heighting, resection, traversing and detail survey applications will be examined both in a theoretical sense and through practical experiences. In this unit, you will also learn to use programmable hand-held calculators and specialist survey software to reduce your field observations, to create professional plans and to report outcomes of your data collection and analysis. The results of surveying projects are are often required to be referenced to a particular coordinate datum. In this unit, you will learn the concepts and methodologies required to reduce and interpret survey data referenced to various datums including the current Map Grid of Australia (MGA2020) and the Australian Height Datum (AHD).

Intended Learning Outcomes

As per the Assessment and Results Policy 1.3, your results will reflect your achievement against specified learning outcomes.

On completion of this unit, you will be able to:


1	Apply survey methodologies for the collection of spatial data.
2	Evaluate survey data using a range of computational techniques.
3	Evaluate a range of survey procedures by relating them to published standards.
4	Employ coordinate transformations in the reduction of survey data.

Teaching arrangements


ATTENDANCE MODE	TEACHING TYPE	LEARNING ACTIVITY	CONTACT HOURS	FREQUENCY
On Campus	Seminar	Two seminars per week will generally follow the structure and topics as described in the Unit Schedule. Notes/slides, recordings and required readings will be uploaded to MyLO after each seminar is completed. Active participation is encouraged during the seminars.	1	2 times per week
	Tutorial	Tutorials will be used to undertake survey calculations, reduce survey data and provide familiarity with Quickclose and Neo survey programs. A HP50 calculator/app with Quickclose installed will be needed for all tutorials. The tutorial sessions provide your primary opportunity for supported learning in the use of the HP calculators and software and are of significant benefit for learning survey computations required for the practical components of the unit and your future careers.	1	Weekly
	Practical	Practical sessions offer a means of developing the skills required to collect survey data with modern instruments, they will also provide time for data reduction and computational work. Staff will be available for support within the timetabled sessions. Practical sessions are a significant part of this unit, it is critical that students attend and participate in both the fieldwork and computational sessions.	3	Weekly

Attendance / engagement expectations

If your unit is offered On campus, it is expected that you will attend all on-campus and onsite learning activities. This is to support your own learning and the development of a learning community within the unit. If you are unable to attend regularly, please discuss the situation with your course coordinator and/or our UConnect support team.

If your unit is offered Online or includes online activities, it is expected you will engage in all those activities as indicated in the Unit Outline or MyLO, including any self-directed learning.

If you miss a learning activity for a legitimate reason (e.g., illness, carer responsibilities) teaching staff will attempt to provide alternative activities (e.g., make up readings) where it is possible.

The contentof the Seminars, Tutorials and Practicals is all linked and directly related to your assessments hance it is critical that you attend and engage with all classes during semester.

How will I be Assessed?

Task Length:

After 4 weeks of field work you will submit a short written technical report (approximately 3-4 pages of technical review, survey results & data analysis).

How your final result is determined

To pass this unit, you need to demonstrate your attainment of each of the Intended Learning Outcomes, achieve a final unit grade of 50% or greater, and pass any hurdle tasks.

Submission of assignments

Where practicable, assignments should be submitted to an assignment submission folder in MYLO. You must submit assignments by the due date or receive a penalty (unless an extension of time has been approved by the Unit Coordinator). Students submitting any assignment in hard copy, or because of a practicum finalisation, must attach a student cover sheet and signed declaration for the submission to be accepted for marking.

Academic integrity

Academic integrity is about acting responsibly, honestly, ethically, and collegially when using, producing, and communicating information with other students and staff members.

In written work, you must correctly reference the work of others to maintain academic integrity. To find out the referencing style for this unit, see the assessment information in the MyLO site, or contact your teaching staff. For more detail about Academic Integrity, see Important Guidelines & Support.

Requests for extensions

If you are unable to submit an assessment task by the due date, you should apply for an extension.

A request for an extension should first be discussed with your Unit Coordinator or teaching support team where possible. A request for an extension must be submitted by the assessment due date, except where you can provide evidence it was not possible to do so. Typically, an application for an extension will be supported by documentary evidence: however, where it is not possible for you to provide evidence please contact your Unit Coordinator.

The Unit Coordinator must notify you of the outcome of an extension request within 3 working days of receiving the request.

Late penalties

Assignments submitted after the deadline will receive a late penalty of 5% of the original available mark for each calendar day (or part day) that the assignment is late. Late submissions will not be accepted more than 10 calendar days after the due date, or after assignments have been returned to other students on a scheduled date, whichever occurs first. Further information on Late Penalties can be found on the Assessments and Results Procedure.

Review of results and appeals

You are entitled to ask for a review of the marking and grading of your assessment task if there is an irregularity in the marking standards or an error in the process for determining the outcome of an assessment. Details on how to request a review of a mark for an assignment are outlined in the Review and Appeal of Academic Decisions Procedure.
