Principles of Engineering Survey

At the end of this course, students should be able to: 1. describe the principles and scope of surveying and geo-informatics; 2. use survey instruments to carry out basic measurements like distance, angles, heights, and coordinates; 3. acquire the skills to process field survey data for the preparation of a large-scale topographic map; and 4. interpret and analyse information on survey plans/maps for planning purpose.

Introduction to the use of basic surveying instruments: (Tapes, Theodolites, Total stations, GPS, and Levels). General principles involved in basic survey measurements: Control and accuracy checks in survey measurements. Sources and theory of errors in survey measurements. Introduction to plane rectangular coordinate systems. Basic Surveying Measurements: Linear & Angular measurements. Classical and modern methods of horizontal position establishment in surveying. Height determination by methods of spirit and reciprocal levelling. Methods of Trigonometrical, Barometric, and Hydrostatic levelling. Introduction to tacheometric surveying. Methods of obtaining field data for topographic surveys. Basic principles and uses of topographic maps. Introduction to photogrammetry.
