General principles of EDMI operation, level, theodolite, total stations. Field procedures for total stations in topographic surveys, surveying applications, and field notes.
Part 2: Measurements and Computations: Units of measurements, Methods of linear measurement, types of measurements. Horizontal angle, horizontal distance, vertical angle, vertical distance. accuracy and precision, errors and mistakes, accuracy ratio, stationing, location methods, accuracy and precision, errors and mistakes, accuracy ratio. Measure horizontal distance, Identify and use different measurements, identify equipment of horizontal measurement, Identify the sources of errors and corrective actions.
Part 3: Leveling: Definitions, types of leveling staff, leveling operations, techniques of leveling, benchmark. Leveling (vertical control survey), profile and cross-section leveling, reciprocal leveling, peg test, errors in leveling, contours and their characteristics, various methods of Contouring.
