1. How can surveying be defined?

Surveying may be defined as the art of making measurement of the relative positions of natural and manmade features on the Earth’s surface, and the presentation of this information either graphically or numerically.

2. How is much of the information of the survey portrayed?

Much of the information of the survey is portrayed graphically or numerically by the construction of maps, profiles, cross-section, and diagrams.

3. How many the process of surveying be divided?

The process of surveying may be divided info the field-work of talking measurements and the office-work of computing and drawing necessary to the purpose of the survey.

4. What was the purpose of the earliest surveys?

The earliest surveys known were for the purpose of establishing the boundaries of land.

5. Why must every construction project be based on surveys?

Because surveys are assistance in the conception, design, and execution of engineering works.

6. What can you say about the level line, the direction of a plumb line and the angles of polygons in plane surveying?

In plane surveying, a level line is considered as mathematically straight, the direction of the plumb line at any point within the limits of the survey is considered as parallel to the direction of the plumb line at any other point, and the angles of polygons are considered as the plane angles.

7. Where are plan surveys employed?

Plane surveys are employed for the location and construction to highways, railroads, canals, and, in general, the surveys necessary for the works of man are plane surveys, as are also the surveys made for the purpose of establishing boundaries, except state and national.

8. In plane surveying, how is the Earth’s surface assumed to be? Why?

In plane surveying, the Earth’s surface assumed to be a plane, because it’s conducted in a small area of the Earth’s surface.

9. What must be taken into account in geodesy surveying? Why?

In geodetic surveying, the curvature of the Earth must be taken into account because large areas of the Earth’s surface are involved

10. What do modern methods in geodesy surveying include?

Modern method for this task include global positional system which us transmissions from satellites to obtain the three dimensional co-ordinates of any point on the Earth’s surface to a high degree of accuracy.
