Surveying and Geomatics Laboratory

Course Objective:

To provide hands on experience in calibration of flow meters, performance characteristics of pumps and turbines.

List of Experiments:

1.Levelling Operations: Fly levelling, check levelling, and benchmark transfer.

2.Contouring and Mapping: Grid levelling, contour mapping, and cut & fill volume estimation.

3.Theodolite Surveying: Measurement of horizontal angles by repetition and reiteration methods.

4.Total Station Surveying: Angle, distance, coordinate measurement, orientation, and resection methods.

5.Height and Distance Measurement: Determination of height using REM/trigonometric methods.

6.GPS Surveying: Navigation and feature collection using handheld GPS.

Tasks: (Perform any 2 tasks)

Task 1: Site Levelling and Earthwork Estimation: Perform levelling and contour mapping to estimate cut and fill volumes for a construction site.

Task 2: Precision Survey and Layout: Measure horizontal angles using theodolite methods and apply them for setting out a simple structure.

Task 3: Total Station Mapping: Conduct a topographic survey using Total Station and prepare contour and feature maps for planning.

Task 4: Height and GPS Survey: Determine heights using REM method and integrate GPS data for mapping infrastructure features.

Weightage: Continuous Assessment: 60%, End Semester Examinations: 40%

Methodology for Continuous Assessment: Project (30%), Assignment (10%), Practical (30%), Internal Examinations (30%)
