i. You have been asked to establish a control network at UniSQ Toowoomba Campus for topographical mapping of campus area located near the Soccer field using an Automatic Level, a Total Station and Tape measurement. The coordinates of B50 (Easting, Northing and RL) is provided. ii. List the 5 (five) fundamental spatial positioning techniques you can use to establish a control network. Describe which method or combination of methods would be most suitable? A level traverse was run and the recording was booked down the page as illustrated in Figure 1. The AHD Datum elevation (RL) was B50 (691.420m). Reduce the level traverse using the Rise and Fall Method and apply all checks as required.
