Survey donation to university grows educational capacity

September 18th, 2017, Published in Articles: PositionIT

The University of South Africa’s (UNISA) Department of Civil and Chemical Engineering recently accepted a donation of survey equipment from survey instrumentation supplier ProtSurv Geo Centre. The donation will allow more students to simultaneously participate in the surveying practical courses.

ProtSurv’s DC van der Walt and Vincent Ratshilumela handed over the donation of two Fujiyama FYT2 theodolites and three Fujiyama FYMD32 levels to Survey 1 and 2 lecturers Thabo Mosiane and Johan Wiesner on 14 September 2017. Two of the ten trig beacons on the survey training site near the university’s Florida Campus have also been renamed Sokkia and Hi-Target in recognition of the company.

Approximately 660 students enrolled in the Survey 1 and Survey 2 courses, and are required to complete five-day practicals at the site as part of their course. The donation will enable more students to be accommodated on the courses. Students are divided into six groups of four for the practical courses which start in July each year. Each group receives one level, one theodolite, two tripods and staves, two rods with supports, and a change point to carry out their assignments.

The Survey 1 practical course covers longitudinal and cross sections to calculate area and volumes, topographic surveys, plot contour plans, and traverse to fix points on the topographic survey, while Survey 2 practicals focus on triangulation fix by resection, setting out and designing a curve, levelling the longitudinal section on the curve, cross sections, traversing, and profiles.

Speaking at the handover, Van der Walt invited students to try ProtSurv’s internally-developed DuoSoft Field survey app for levelling. Students can use this Android app with its 30-day free trial to carry out final checks on their calculations. He added that his company is currently working on a total station component for the app. Ratshilumela explained how the app can be useful in calculating rise-and-fall, elevations, reduced elevations, and profile levelling among others.

Wiesner also said that the university will be looking to incorporate the app into the training programme, as this is the sort of tool surveyors would typically be using in their daily work in the industry.
