Curves – Necessity – Types, Simple curves, Elements , Designation of curves, Setting out simple curves by linear methods (numerical problems on offsets from long chord & chord produced method), Setting out curves by Rankine’s deflection angle method (numerical problems). Compound curves, Elements, Design of compound curves, Setting out of compound curves (numerical problems). Reverse curve between two parallel straights (numerical problems on Equal radius and unequal radius). Transition curves Characteristics, numerical problems on Length of Transition curve, Vertical curves –Types – (theory).
Photogrammetry and aerial survey:
Introduction, definitions, basics principles, methods, importance of scale, height, applications.

Global Positioning System:
Definition, Principles of GPS and applications. Geographical Information System: Introduction and principle of Geographical Information System, components of GIS, applications Advanced instrumentation in surveying: classification, measuring principles, Electronic theodolite, EDM, Total Station, Drones
LABORATORY EXPERIMENTS
1. Study of various instruments used for surveying, namely chain, tape, Compass,
2. Dumpy level, Auto-level, Theodolite, Tacheometer, Total station and GPS. To find the distance between two points shown in the field using method of pacing, chaining and taping.
3. To set regular geometric figures (Hexagon and Pentagon) using chain tape and accessories.
4. To set regular geometric figures (Hexagon and Pentagon) using prismatic compass, given the bearing of one line.
5. Study of use of Dumpy level and to determine the different in elevation between two points by differential levelling using Dumpy level
6. To find the true difference in elevation between two points situated far apart by using Reciprocal levelling.
7. Trigonometrical levelling: Single plane method and Double plane method
8. Measurement of horizontal angle using theodolite by: i) Method of Repetition and ii) Reiteration method.
9. Setting simple circular curve-Instrumental method,
10. Setting compound curve using theodolite
11. Plane table : Setting, orientation, radiation, intersection
12. Demo: Total station, GPS
Course outcome (Course Skill Set)
At the end of the course the student will be able to :
1. Execute survey using compass and plane table
2. Find the level of ground surface and Calculation of area and volumes
3. Operate theodolite for field execution
4. Estimate the capacity of reservoir
5. Interpret satellite imageries
Assessment Details (both CIE and SEE)
Continuous Internal Evaluation:
Three Unit Tests each of 20 Marks (duration 01 hour)
1. First test at the end of 5th week of the semester
2. Second test at the end of the 10th week of the semester
3. Third test at the end of the 15th week of the semester
Two assignments each of 10 Marks
4. First assignment at the end of 4th week of the semester
5. Second assignment at the end of 9th week of the semester
Group discussion/Seminar/quiz any one of three suitably planned to attain the COs and POs for 20 Marks (duration 01 hours)
6. At the end of the 13th week of the semester The sum of three tests, two assignments, and quiz/seminar/group discussion will be out of 100 marks and will be scaled down to 50 marks (to have less stressed CIE, the portion of the syllabus should not be common /repeated for any of the methods of the CIE. Each method of CIE should have a different syllabus portion of the course).
CIE methods /question paper is designed to attain the different levels of Bloom’s taxonomy as per the outcome defined for the course.
Semester End Examination:
Theory SEE will be conducted by University as per the scheduled timetable, with common question papers for the subject (duration 03 hours)
1. The question paper will have ten questions. Each question is set for 20 marks.
2. There will be 2 questions from each module. Each of the two questions under a module (with a maximum of 3 sub-questions), should have a mix of topics under that module.
The students have to answer 5 full questions, selecting one full question from each module
