Basic principle of Surveying “working from whole to part” is: |
A) to complete the work rapidly
B) to prevent accumulation of errors
C) to avoid mistakes in work
D) All of the above
A plan drawn to a scale of 1:4000 was measured by a scale of 1:5000. The % error in the length measured will be: |
A) 10
B) 1000
C) 25
D) 1.25
‘Representative Fraction’ (RF) is defined as |
A) Length of an object in the drawing / Actual length of the object
B) Length of an object in the drawing / Isometric length of the object
C) Actual length of the object / Length of an object in the drawing
D) Isometric length of the object / Length of an object in the drawing
The plan of a map was photocopied to a reduced size such that a line originally 120 mm, measures 90 mm. The original scale of plan was 1:1000. What will be the revised scale? |

B) 1: 1232
C) 1: 1333
D) 1: 1121

B) 1/400000
C) 1/400
D) 1/16000
A Topographic survey involves measuring |
A) elevation of points
B) horizontal distances of points from a reference station or line

The process of translating the plan of a work on actual ground in exact position in three dimensions is called |
A) Tacheometry
B) planning of a work
C) setting out of work
D) plane table survey
A diagonal scale is used for measuring |
