What is the difference between plane Survey and geodetic Survey by length?
The line joining any two points is treated as the arc of the circle. Length up to 12KM is treated as plane surveying. Length more than 12KM is treated as geodetic surveying. A triangle formed by joining three points is considered as plane triangle and angles formed are considered as trigonometry is required.
Which survey assumes the surface of earth as plane?
Geodetic Survey
All triangles formed by survey lines are considered as a plane triangle. Geodetic Survey: The surveys in which the curvature of the earth is taken into consideration are known as geodetic surveying.
What is plane surveying in geography?
– PLANE SURVEYING. This is a branch of surveying which assumes that the survey area is a flat plane. It neglects the curvature of the earth. The area measured is considered as being plane.
What is the purpose of plane surveying?
Ordinary field and topographic surveying in which Earth curvature is disregarded and all measurements are made or reduced parallel to a plane representing the surface of the Earth. The accuracy and precision of results obtained by plane surveying may decrease as the area surveyed increases in size.
What is the main principle of surveying?
Two basic principles of surveying are: • Always work from whole to the part, and • To locate a new station by at least two measurements ( Linear or angular) from fixed reference points. area is first enclosed by main stations (i.e.. Control stations) and main survey lines.
What are the objectives of plane and geodetic surveying?
They are used for the precise location of a widely distant area. Plane surveying uses normal instruments like a chain, measuring tape, theodolite, etc. Geodetic surveying uses more precise instruments and modern technology like GPS.
What is the first principle of surveying?
What is the first principle of surveying? Explanation: The first principle of surveying is to work from whole to part. Before starting the actual survey measurements, the surveying is to work from around the area to fix the best positions of survey lines and survey stations.
What are the types of geodetic survey?
Four traditional surveying techniques (1) astronomic positioning, (2) triangulation, (3) trilateration, and (4) traverse are in general use for determining the exact positions of points on the earth’s surface.

What are the uses of surveying?
Uses of Surveying
- Topographical maps showing hills, rivers, towns, villages, forests etc.
- For planning and estimating new engineering projects like water supply and irrigation schemes, mines, railroads, bridges, transmission lines, buildings etc.
What are the types of surveying?

What are the three basic principles of surveying?
Basic Principles of Surveying
- BASIC PRINCIPLES IN SURVEYING.
- PRINCIPLE OF WORKING FROM WHOLE TO PART.
- IMPORTANCE OF SCIENTIFIC HONESTY.
- CHECK ON MEASUREMENTS.
- ACCURACY AND PRECISION.
- Horizontal Distance Measurement.
Which is more accurate geodetic surveying or plane surveying?
1. Mainly, plane surveying ignores the curvature of the earth, while geodetic surveying consider it. 2. Plane surveying is suitable for small areas, whereas Geodetic surveying suits for surveying of large area. 3. Geodetic surveying is more accurate than plane surveying.
What’s the difference between plane surveying and surface surveying?
The plane surveying is that type of surveying which does not take into account the curvature of the earth, and the surface of the earth is treated as a plane surface.
Which is considered a straight line in plane surveying?
Line joining any two stations is considered to be straight The triangle formed by any three points is considered as plain Carried out for a small area of <250 km Plane surveying uses normal instruments like chain, measuring tape, theodolite etc.
How is the curvature of the earth’s surface ignored?
Plane Surveying Effect of the curvature of the earth’s surface is ignored. Geodetic Surveying Effect of the curvature of the earth’s surface is included. Length up to 12KM is treated as plane surveying. Length more than 12KM is treated as geodetic surveying. Involves smaller areas less than about 260 km 2.
