You’ll be tasked with preparing information and resources for your field team, and undertaking a variety of calculations and analysis on their observations.
1.2. Assignment topics
This assignment focuses on content in Modules 1 to 3. Additional knowledge from prerequisite subjects will also need to be utilised.
For more information on the course topics that this assignment relates to, please see the course specification page. This is linked through the course StudyDesk. Individual courses can be searched here.
1.3. Assignment Value
Assignment 1 is a 20% (200 mark) assessment. A summary of mark distribution for the assignment is given in Table 1.3.
Task 1 30 marks
Task 2 20 marks
Task 3 60 marks

1.4. Due Date
This assignment is due on Monday 6th September 2021 at 11.59pm USQ time.
1.5. Late penalty
For each day that an assignment is late, a penalty of 5% of the total assignment marks will be deducted.
Please refer to the University Procedure for Assessment - https://policy.usq.edu.au/documents/14749PL
If you are in a situation where you believe you are going to need to request an extension for an assignment, it is advisable to get in contact with the lecturer as soon as possible – the day an assignment is due is not appropriate!
1.6. Assignment presentation guidelines
It is expected that you will submit a report style submission for this assignment – professional report writing and presentation is a skill that should be developed alongside technical knowledge throughout your university career. The USQ library has many resources about assignment structure and writing for students that can be accessed here.
At minimum, your report should contain:
• A title page indicating the course code (SVY3107), assignment number, and your name and student number
• Clearly labelled answers linking them to the relevant assignment questions
• Page numbers
Your report should be submitted in PDF file format to ensure formatting issues between different software packages is avoided.
Any published material you refer to should be properly referenced and included in a bibliography or list of references at the end of your assignment. You should use the Harvard AGPS style of referencing. See the library website for further details on referencing.
All the information required to address the assignment questions needs to be included in your report, however you are required to also submit a copy of your spreadsheet that is used to address task 2. This spreadsheet will be tested with an independent set of data by the marker, so ensure any values that are needed for answering other parts of the assignment are included in the PDF file (i.e. make sure your answers for task 3 are in your PDF not just in the spreadsheet!).
Some tips for the presentation of your spreadsheet are:
• Make sure all columns have clear headings
• Make sure rows have labels where appropriate, particularly when showing a result
• Use cell outlines and shading to make your spreadsheet easy for people to understand
• Make sure the sheets are labelled appropriately to make it clear which task it is addressing
1.7. Submission Instructions
All submissions should be digital, and made through the StudyDesk Assignment submission link.
Your assignment submission should include:
o 1 PDF file of your assignment
o 1 MS Excel compatible spreadsheet/workbook
Please ensure your name, student number (the 6001234567 number), and course code (SVY3107) appear at least once in the body of your assignment. Please also ensure that you clearly label each of your solutions with the corresponding question number (e.g. Task 1).
Use the following naming convention for your files:
o SVY3107_A1_[SurnameInitial]_[StudentNumber].pdf
o Where [SurnameInitial] is replaced by your surname and your first initial (eg Chris
McAlister would be McAlisterC); and o [StudentNumber] is replaced by your 10 digit student number (e.g. 6001234567)
o Please note the size of your files cannot exceed 100MB.
1.8. Equipment Required
You will need internet access to access the relevant software packages and assignment resources.
You will need to use a spreadsheet program, such as Google Sheets or MS excel to complete this assignment. You have access to Google Sheets through your student account online.
1.9. Further questions
If you have any questions about the assignment, please contact the course examiner Chris McAlister via the Course Slack assignments channel.
2. Assignment Body
2.1. Introduction
You have been asked by a client to examine some old traverse data between marks on a site where they will be developing significant infrastructure. While most of the original survey data has been lost, there are a number of connections between different marks that have been provided to you as shown below in Table 2.1.1, Table 2.1.2 and Table 2.1.3. All coordinates have been transformed to GDA2020.
Station number Latitude Longitude AHD Height AUSGeoid2020 (N)
Station 1 -27° 45’ 43.9192” 143° 56’ 0.0080” 137.261m To be determined
Station 2 No data available No data available No data available No data available
Station 3 -28° 05’ 43.2384” 144° 07’ 55.6608” 141.277m To be determined
Station 4 No data available No data available No data available No data available
Station 5 To be determined To be determined To be determined To be determined

2.2. Tasks (200 marks total)
Please see below for the tasks you need to complete.
You may use excel or similar to undertake the calculations, however you must ensure a copy of the results are pasted into your final report. Reports that direct the reader to refer the spreadsheet will get zero marks for that task. Also ensure all your calculations are clearly labelled and explained for the reader.
2.2.1. Task 1 – AUSGeoid (30 marks)
Using the data provided to you;
a) determine the AUSGeoid Values for Stations 1 and 3 (10 marks)
b) Briefly discuss your choice of AUSGeoid model, explaining what the main components of that model are and why it is best suited to this data (20 marks)
2.2.2. Task 2 – Survey sketch (20 marks)
Using the data provided, develop an appropriate sketch (hand drawn is ok) to show the data provided to you clearly. Ensure all the stations are clearly annotated with the data associated with them, and that provided information is clearly distinguished from calculated or determined data (20 marks)
2.2.3. Task 3 – Triangles, triangles and more triangles (60 marks)
Before looking at the larger traverse, completing some initial calculations on the closed shapes in the survey is advisable.
Using your knowledge of spherical and spheroidal triangles, for the triangle formed by Stations 2, 3 and 5, determine:
a) The geodetic internal angles (10 marks)
b) The distance between Station 2 and 3 (10 marks)
c) The excess in the triangle (10 marks)
d) The plane internal angles (10 marks)
e) Coordinates of station 2 and station 3 (20 marks)
You can assume that the skew normal and deflection of vertical corrections have already been made to the angles.
2.2.4. Task 4 – Arc to Chord to Arc to Chord… (50 marks)
You will eventually need to reduce the traverse to determine how reliable the previous survey was. As you’ll want to check the survey by running the traverse from multiple directions, you need to develop a spreadsheet that will allow you to reduce the distance measurements to the ellipsoid.
Some tips in making your spreadsheet:
• Ensure the input fields are clear and that there are appropriate instructions included so it is easy to use and understand.
• Each step should be clearly labelled, and any solutions should be clearly identified
• You may select your own input values for any variables not provided in this assignment sheet, but they must be clearly documented.
NOTE: Your spreadsheet will be validated with another dataset as part of the marking process.
2.2.5. Task 5 (40 marks)
Using the spreadsheet you developed in Task 4, and the additional data provided in the table below calculate the ellipsoid distance of the traverse lines between Stations:
a) 1-2 (10 marks)
b) 1-4 (10 marks)
c) 3-4 (10 marks)
d) 2-3 (10 marks)
2.3. Rubric/Marking guide
