  2. 2. infinity-project.org The Caruth Institute for Engineering Education Engineering Education for today’s classroom. M.Shanmugaraj Lec/Civil VSVN POLYTECHNIC COLLEGE., VIRUDHUNAGAR DEPARTMENT OF CIVIL ENGINEERING SURVEYING Surveying is the science and art of determining the relative positions of points above, on, or beneath the earth’s surface and locating the points in the field.
  3. 3. infinity-project.org The Caruth Institute for Engineering Education Engineering Education for today’s classroom. M.Shanmugaraj Lec/Civil VSVN POLYTECHNIC COLLEGE., VIRUDHUNAGAR DEPARTMENT OF CIVIL ENGINEERINGThe work of the surveyor consists of 5 phases 1.Decision Making–selecting method, equipment and final point locations. 2.Fieldwork & Data Collection–making measurements and recording data in the field. 3.Computing & Data Processing–preparing calculations based upon the recorded data to determine locations in a useable form. 4.Mapping or Data Representation–plotting data to produce a map, plat, or chart in the proper form. 5.Stakeout –locating and establishing monuments or stakes in the proper locations in the field.
  4. 4. infinity-project.org The Caruth Institute for Engineering Education Engineering Education for today’s classroom. M.Shanmugaraj Lec/Civil VSVN POLYTECHNIC COLLEGE., VIRUDHUNAGAR DEPARTMENT OF CIVIL ENGINEERING Categories of Surveying 1.Plane Surveying–surveying with the reference base for fieldwork and computations are assumed to be a flat horizontal surface. 2.Geodetic Surveying–surveying technique to determine relative positions of widely spaced points, lengths, and directions which require the consideration of the size and shape of the earth. (Takes the earth’s curvature into account.)
