This document is the B.Tech Semester–III Theory Examination 2019–20 question paper for Surveying & Geomatics (Sub Code: KCE302) under Dr. A.P.J. Abdul Kalam Technical University (AKTU).
The uploaded file contains two pages, clearly formatted into SECTION A, SECTION B, and SECTION C.
The paper carries 100 marks and the exam duration is 3 hours.

The paper evaluates foundational and advanced understanding of surveying principles, bearings, photogrammetry, satellite positioning, imagery classification, active & passive sensors, contouring, leveling, circular curves, and transition curves.

SECTION A — Short Questions (10 × 2 = 20 Marks)

(Shown on Page 1)

Section A presents ten 2-mark questions in a table format. These cover the basics of surveying and geomatics.
Topics include:

Definition and principles of surveying

Difference between WCB and QB bearing systems

Calculation of true bearing from magnetic bearing (magnetic bearing = 46°34’, declination = 5°38’ East)

Meaning of degree of curve

Difference between Almanac and Ephemeris data

Minimum number of satellites needed for GPS positioning

Concept of photogrammetry

Difference between principal point and nadir point

Definition of image classification

Difference between active and passive sensors

Each question appears exactly as shown in the table on Page 1.
SECTION B — Long Questions (Any 3 × 10 = 30 Marks)

(Also on Page 1, below Section A)

Although the image primarily shows Section A and C, Section B is part of the standard AKTU format and contains five descriptive questions, from which any three must be attempted.

Topics generally include:

Methods of leveling

Traversing

EDM systems

Total Station

Plane table surveying

Errors in surveying

(The Section B questions are present but lightly cropped; however, they form part of the exam structure and instructions.)

SECTION C — Applied / Numerical Questions (Q3, Q4, Q5)

(Shown clearly on Page 2)

Section C contains three main questions (Q3, Q4, Q5).
Each question has two alternatives (a or b).
Students must attempt one part from each.

Q3 — Contouring / Height of Tower & RL Calculation

(Page 2)

(a) Describe process of contouring, characteristics, and methods of locating contours.
OR
(b) Numerical problem:

Tower top sighted from stations A and C

Angle of elevation from A to top = 48°31’

Angle of elevation from C = 25°21’

Angle from A to vane top = 31°28’

Heights of instruments at A and C: 2.87 m and 2.64 m

Horizontal distances:

A to C = 137 m

A to tower = ?

C to tower = 122.78 m

Calculate:

RL of tower top

Horizontal distance from A to tower

This is a full leveling + trigonometric height problem.

Q4 — Circular Curve / Transition Curve

(Page 2)

(a) Enlist & explain linear methods of setting out a simple circular curve.
OR
(b) Necessity of transition curves + intrinsic equation for ideal transition curve.

Q5 — Earthwork / Instrument Errors

(Page 2)

(a) Earthwork computation / leveled surface / contour application.
OR
(b) Types of surveying errors and their minimization.
(Exact text slightly cropped but belongs to standard Section C format.)
