My first year I was train on Altimetry (Direct leveling and indirect leveling). Direct leveling we used leveling instrument to survey roads from which we can deduce the altitude of different points on a road from which we can draw both the traverse and longitudinal profile of the road. Here we use a leveling machince, staff, tripot. we survey the back side and the front side, the back side is considered the bench mark ( known in altitude) to calculate the rise and fall we take the back site minus the front side. then to calculate the altitude of the next point lets say B we take the rise or fall and add with altitude of A (benchmark). we also used the Total station to carry out indirect leveling. we did the survey computations and drawing of the road profile. My second year was more on planemetry survey (Cadastral surveys) which involves mapping of land into layouts for construction of settlements. We also carried out topographic surveys on plots for the purpose of a building permit and also for mapping out of roads. We went for a 5 weeks of internship at any organization or company to enable us have field experience and also to treat technician files. Lastly we where split into groups of 5 and we were given hectares of land to carry out topographic Survey using the Total station. we were given coordinates to track our area of work with the help of Garmin GPS then we used the Total station to implant the boundaries Beacons. Afterward we drew a sketch map of the area to be surveyed including all the details found in the area.( buildings, brigades, water chanteur, taps, streams, valley, road, electric poles, vegetation etc. Among 5 of us in our brigade, we splided the tasks, I was the secretary and head of the team, my other four colleagues were, instrument operator, sketch map interprinter and 2 prism holders. we carried out a perimeter survey (Surveying the Beacons we demarcated in 3D and we did double rotation of the horizontal and vertical axis of the instrument in other to minimize our errors in angles and distances). we then proceeded in surveying the details, that's the buildings, bridges, taps, streams, valley, roads, electric poles, vegetation, natural ground. lastly we connected there area we surveyed to the National Geoigetic point found in National Advanced School of Public Works Annex-Buea. At the end of our 3 days of field work, we went to the class and input all the data obtained from the field into Excel and used the Covadi/AutoCAD software to carry out computations. Lastly we drew the 3D map of the area with contours, map of the polygon surveyed, including the survey field book, sketch map, survey report and constituted a technical file which we then submitted to the department for our end of year evaluation. Lastly during this 5 weeks of internship we wrote on our internship booklet and submitted it to the department, and a topic was selected by our internship supervisors to write an end of year report.
