Surveying MCQ - Group 1
Q.1. Hydrographic surveys deal with the mapping of______
Large water bodies
Traffic
Road
Land
Hydrogaphic word made from two words" Hydra + Graphic". Hydra means "Water" and graphic means drawing or mapping. Hence, hydrographic surveys deal with the mapping of large water bodies.
Q.2. Pick up the correct statement from the following:
The diaphragm plays no part in defining the line of sight
The focusing screw plays important role in defining the line of sight
The eyepiece plays no part in defining the line of sight
The optical centre of the objective plays no part in defining the line of sight
Form definition of line of sight, the imaginary line joining optical center of object glass and diaphragm is called as "Line of sight". There fore correct ans. is Option - 3.
Q.3. Principle of surveying followed to prevent accumulation fo errors is,
to work from whole to a part.
to work from part to whole.
both above.
none of the above.
This principle of surveying; work from whole to the part. If we want to make map of country the first cover boundary of country and main parts then go to the sub parts, then we will get correct map. Otherwise we start prepare map form small point to the whole country there will lots of error occurred. There fore correct answer is Option - 1.
Q.4. The curvature of earth's surface is taken into account only if the extent of survey is more than,
60 km2.
160 km2.
260 km2.
none of the above.
As we observe ground surface at normal ground level we feel that surface of ground is plane in nature. But We know that surface of earth is in curvature nature. This curvature nature is clearly observed in sea area. If we carry out survey work for small area (i.e. area < 260 km2) then this curvature will not affect on our work. But if area is greater than 260 km2 then we have to consider this effect. There fore correct answer is Option - 3.
Q.5. Geodetic survey is different form plan surveying because of
very large area is covered.
the curvature of earth is considered.
Large difference of elevations.
undulation of topography.
Basically surveying branch is divided in two parts,
1. Plane surveying
2. Geodetic surveying
1. Plane surveying is branch of surveying in which curvature of earth surface is not considered.
2. Geodetic surveying is branch of surveying in which curvature of earth surface is considered.
There fore correct answer is Option - 2.
1. Plane surveying
2. Geodetic surveying
1. Plane surveying is branch of surveying in which curvature of earth surface is not considered.
2. Geodetic surveying is branch of surveying in which curvature of earth surface is considered.
There fore correct answer is Option - 2.
Q.6. Engineering survey is carried out to
locate boundaries of fields and houses
determine quantities and for collection of data for reservoirs
lay out plots and water supply system and sewers
all of the above
In survey we carry work to collect data form field and record or plot it on paper called map. Some time we locate point form paper or map to ground.
There fore correct answer is Option - 4.
There fore correct answer is Option - 4.
Q.7. The smallest length that can be drawn on map is
1cm
0.6mm
1mm
0.2mm
If we draw a line on paper by sharp edge pencil then the thickness of that line is 0.2mm
There fore correct answer is Option - 4.
There fore correct answer is Option - 4.
Q.8. In chain survey
chainage is distance of the object long the chain line form the zero end of the chain.
oblique offsets are used to locate building corners.
both A and B.
none of the above
Q.9. Chain survey is suitable when
plan required on a large scale.
area is small.
nature of ground is fairly leveled and consist with simple details.
all of the above
Chain survey is difficult when area is not leveled like hilly areas. In city areas where lot of obstacles for ranging and chaining.
There fore correct answer is Option - 4.
There fore correct answer is Option - 4.
Q.10. The well conditioned triangle has angles not less than and more than respectively
900 and 1200.
100 and 900.
200 and 1200.
none of the above
The triangle which angles are not less than 900 and not greater than 1200 are called well conditioned triangle.
There fore correct answer is Option - 1.
There fore correct answer is Option - 1.
