### UNIT I –  SURVEYING – I

#### 2 Marks

1. Define Surveying. What are the fundamental principles of surveying?
Surveying is an art of determining the relative positions of various points on, above or below the surface of the earth by means of direct or indirect measurement of distance, direction and elevation.
The principles of surveying are:
(i) Working from whole to part.
(ii)To locate a new station by at least two measurements (angular, linear) from fixed reference points.
2. What is the object or purpose of surveying?
The primary object of surveying is to prepare a plan or map to show the relative position of the objects on the surface of the earth. It is also used to determine the areas, volumes and other related quantities.
3. Name the different ways of classification of surveys.
a. Primary classification
(i). Plane surveying (ii). Geodetic surveying.
b.Secondary classification
(i). Based on instruments used (ii).Based on methods.
(iii). Based on object (iv). Based on nature of the field
4. Differentiate between plane and geodetic surveying.

 Sl.No. Plane surveying Geodetic surveying. 1. The curvature of the earth is neglected. The curvature of the earth is taken. 2. A line joining any two points is considered straight. A line joining any two points is considered as curved line. 3. The triangle formed by any three points is considered as plane triangle. The triangle formed by any three points is considered as spherical triangle. 4. It is done on a area less than 250 It is done on a area greater than 250 Km 2 Km 2

5. Define the constructions of a diagonal scale.
For a given short length ( PQ=PR), draw a right angle triangle. Its base( PR) and height (PQ) are equal. A short length is divided into a number of parts by using the principle of similar triangles in which like sides are proportional.
Thus, 1-1 represents 1/ 10 PQ
9-9 represents 9/ 10 PQ
