Assignment Body2.1. IntroductionYou have been asked by a client to continue to provide survey information for their large development site.You have previously completed calculations using old traverse data for five main control marks on the site, Stations 1 to Station 5.Your client has asked you to continue work in this same area, primarily traversing between Station 1 and Station 3, with connection through Station 2.The following assumptions can be made:• All distances have been reduced to the ellipsoid• Skew normal and deflections have been corrected for• Various geographic observations of angles and distances, as shown in Appendix A• All coordinates are in GDA2020, unless specifically stated otherwise.• Your field team has provided a traverse for you, connecting the start point (Station 1) and end point (Station 3) through Station 2 and additional control points. These are shown in the field notes sketch shown in Appendix A. This information should be used for tasks 2, 4 and 5.• The GDA2020 coordinates for Stations 1 and 3 are given in the table below.Point name Latitude Longitude AHD Height AUSGeoid2020 (N)Start Point – Station 1 -27° 45’ 43.9192” 143° 56’ 00.0080” 137.261m 25.366mEnd point – Station 3 -28° 05’ 43.2384” 144° 07’ 55.6608” 141.277m 25.301m2.1.1. Task 1 (75 marks)Your field team has provided a traverse for you, connecting Station 1 to Station 3, through Station 2.These are shown in the field notes sketch shown in Appendix A.Your office has also recently employed a graduate who is a guru at coding, so they are being tasked to develop a small program based on your instructions for geodetic traverse reduction.You are required to provide your graduate with:• A comprehensive list of instructions detailing the steps that are required to reduce a geodetic traverse (up to but not including adjustment of linear misclose), working in geographic coordinates (on the ellipsoid). You should include expected input, units and a brief description of steps purpose and the calculation occurring.• Indications of any checks needed.• A workflow diagram for clarity.Note: you may direct your graduate to existing calculation tools, but you must indicate what these are, including links, and still explain what the calculator is undertaking in the process.2.1.2. Task 2 (25 marks)The graduate has reviewed your instructions and has requested a sample of data (called Test Case 1) to ensure their code is working correctly.Using the data from your survey, you need to test your process from Task 1 to reduce the traverse, to provide the graduate with data for Test Case 1.The worked example for Test Case 1 should be a tabulated collection of data that includes:• Links to your instructions provided in Task 1• Input values for each step of the process• Results for each step of the process• Any assumptions you have made for variables• Notes & references indicating where you have used existing calculator programs or spreadsheets to arrive at particular answers so the graduate can understand how results have been achieved.2.1.3. Task 3 (75 marks)The graduate also wants to incorporate the process for reduction of a geodetic traverse on the grid into the program they are writing.You are required to provide your graduate with:• A comprehensive list of instructions detailing the steps that are required to reduce a geodetic traverse (up to but not including adjustment of linear misclose), working on the grid. You should include expected input, units and a brief description of steps purpose and the calculation occurring.• Indications of any checks needed.• A workflow diagram for clarity.Note: you may direct your graduate to existing calculation tools, but you must indicate what these are, including links, and still explain what the calculator is undertaking in the process.2.1.4. Task 4 (25 marks)You guessed it; the graduate needs a test case to test their work!Using the data from your survey, you need to reduce the traverse, to provide the graduate with a worked example for Test Case 2.As previously, the worked example for Test Case 2 should include:• Links to your instructions provided in Task 3• Results for each step of the process• Any assumptions you have made for variables• Notes & references indicating where you have used existing calculator programs or spreadsheets to arrive at particular answers so the graduate can understand how results have been achieved.2.1.5. Task 5 (50 marks)Your client is getting ready to undertake more preparatory work on their site and has requested you peg out the mid points of the line from Station 1 to Station 2 and the line from Station 2 to Station 3.Your graduate thinks they can just code the calculations to average the end point coordinates to calculate the mid points.You are unimpressed.Using the previously calculated values from your traverse reductions, you need to:1. write instructions and2. provide the calculations supporting your instructions, which will be called ‘Test Case 3’to prove to the graduate why their technique isn’t going to cut it, while also providing the client with the information they need.You might like to consider:• The different ways the coordinates of the needed stations might be calculated.• Discussing any discrepancies between forward and reverse values and explaining why these occur.• Which zones the marks fall in and how this might impact calculations2.1.6. Task 6 (50 marks)One of the departments involved in the project need to have the coordinates for the points in Task 5 provided in MGA94.You graduate is taking a well-earned day off but will be looking into transformations on their return.You’ll need to prepare some information for them on the different types of coordinate transformations available, and you will need to make a recommendation on the type that they should implement.You might like to provide them with an indication of the different accuracies of each type, including an estimate of what the different outputs might produce from a test point.2.2.
