Traverse surveys. Azimuth and coordinate computations. Area and coordinate computations. Stadia survey. Trigonometric leveling. Contour lines. Curve layout. Remote sensing and photogrammetry.

Course Objectives:
Civil engineers perform their construction and design activities on and for the surface of earth. They will need information (in form of maps, plans, digital terrain models. Geographic information systems etc.) about the location of the civil work. They will select the location of project and design the structure accordingly. The project will be laid out and constructed by methods of surveying. The cost estimation. Quantity Surveying and work planning will require information and methods of surveying. The students of civil engineers should be able; to use survey instrument, maps, plans, and computer programs; to carry out office and field operations in order to determine geometry of natural artificial features on the surface of the earth in order to prepare maps and plans; to prepare the data for lay out civil engineering structures in construction site; to communicate and use services of professionals in the field of surveying
