Course outcomes:

After a successful completion of the course, the student will be able to:

1. Posses a sound knowledge of fundamental principles Geodetics.

2. Measurement of vertical and horizontal plane, linear and angular dimensions to arrive at solutions to basic surveying problems.

3. Capture geodetic data to process and perform analysis for survey problems.

4. Analyse the obtained spatial data and compute areas and volumes. Represent 3D data on plane figures as contours.

Question paper pattern:

• The question paper will have ten full questions carrying equal marks.
• Each full question will be for 20 marks.
• There will be two full questions (with a maximum of four sub- questions) from each module.
• Each full question will have sub- question covering all the topics under a module.
• The students will have to answer five full questions, selecting one full question from each module.
