Define Survey. Classify it
Answers
Answer:
Surveying is the art to determine the relative position of object on or below the surface of the earth by measuring horizontal distance between them and prepare a map to any suitable scale. Classification of surveying- 1) Primary classification –primary surveying can be divided into two type. a) Plane surveying.
Answer:
Defination-
Surveying is the technique of determining the relative position of different features on, above or beneath the surface of the earth by means of direct or indirect measurements
Classification of survey-
PLANE SURVEYING
PLANE SURVEYING
PLANE SURVEYING PLANE SURVEYING is a process of surveying in which the portion of the earth being surveyed is considered a plane. The term is used to designate survey work in which the distances or areas involved are small enough that the curvature of the earth can be disregarded without significant error. In general, the term of limited extent. For small areas, precise results may be obtained with plane surveying methods, but the accuracy and precision of such results will decrease as the area surveyed increases in size. To make computations in plane surveying, you will use formulas of plane trigonometry, algebra, and analytical geometry.
GEODETIC SURVEYING is a process of surveying in which the shape and size of the earth are considered. This type of survey is suited for large areas and long lines and is used to find the precise location of basic points needed for establishing control for other surveys. In geodetic surveys, the stations are normally long distances apart, and more precise instruments and surveying methods are required for this type of surveying than for plane surveying.
