Surveying is the technique of determining the relative position of different features on, above or beneath the surface of the earth by means of direct or indirect measurements and finally representing them on a sheet of paper known as plan or map.
CE 262 Surveying lecture is composed by theoretical and practical work. Theoretical part is performed in the classroom while practical work part in performed via surveying land in Yeditepe’ campus area.
Traverse points established on university campus. Traverse edges and angles between them are measured by students through modern technical devices (Total Station). Coordinate of traverse points are calculated by students using surveying results. Leveling is done between traverse points. Elevation of traverse points are calculated according to see level via levelling instrument. From the plans, sections, and maps prepared by surveying, the area and volume of a particular plot of land can be calculated.
Importance of Surveying
The knowledge of surveying is advantageous in many phases of engineering. Surveying is of vital importance in any engineering project. Some of the basic importance of Surveying is discussed below.
- The first necessity in surveying is to prepare a plan and a section of an area to be covered by the project. From these prepared maps and sections the best possible alignment, amount of earthwork and other necessary details depending upon the nature of the project can be calculated.
- The planning and design of all Civil Engineering projects such as railways, highways, tunneling, irrigation, dams, reservoirs, waterworks, sewerage works, airfields, ports, massive buildings, etc. are based upon surveying measurements.
- During execution of the project of any magnitude is constructed along the lines and points established by surveying.
- The measurement of land and the fixation of its boundaries cannot be done without surveying.
- The economic feasibility of the engineering feasibility of a project cannot be properly ascertained without undertaking a survey work.
- The execution of hydrographic and oceanographic charting and mapping requires.
Surveying is used to prepare a topographic map of a land surface of the earth.
