Surveying - Primary Division

Surveying is an art of determination of the relative position of the points on above or below the surface of the earth by some direct or indirect linear and angular measurements.
Leveling is a branch of surveying in which we locate the points at some given elevation or determine the elevation of the given points.

Main objective of the surveying is to prepare the maps or plan of a given area. The term map is used when we have to prepare the horizontal projection of a relatively larger area on a paper sheet.
The term 'plan' is used when the area is relatively smaller.

Primary Division of Surveying
Earth is an ellipsoid. There is difference of about 43km between the diameter of the earth along the equatorial plane and that along the polar axis. When we draw a triangular traverse on a level surface  then the triangle formed is known as a spherical triangle and the angles are known as the spherical angles.
When we draw the chord of a 12km level arc the difference in th…

Transportation Engineering

Importance  :

Transportation adds to the economic, industrial, social and cultural development of a country. Transportation is very important for the economic development of any region since every thing/commodity produced whether it is food, fruits or industrial products needs transport at all stages from production to distribution. In the production stage, transportation is required for carrying raw materials like seeds, manure, coal, steel etc. In the distribution stage, transportation is required from the production centers viz; farms and factories to the marketing centers and later to the retailers and the consumers for distribution.
The inadequate transportation facilities retard the process of social & economic development of the country. The adequacy of transportation system of a country indicated its economic and social development.

a) Economic activity and Transport:   The importance of transportation in economic activity is to be found in its effects on both human wants …

Civl Engineering - An Introduction

If you search the wikipedia then the definition of of Civil Engineering is  "Civil Engineering is a branch of Engineering which deals with the design, construction and maintenance of the physical and natural environment including works like roads, bridges, canal, dams and buildings."
In earlier times there was only one discipline and that is Military Engineering. The military people use to construct the varoius kinds of structures like bridges and bunkers etc for their own purpose.
To dinstinguish the same works done for the public from the works done by military it was named like Civil Engineering.
Civil Engineering is the oldest trade after the Military Engineering. It is sub divided into various sub-disciplines
1. Environmental Engineering
2. Geotechnical Engineering
3. Structural Engineering
4. Transportation Engineering
5. Municipal Engineering/ Urban Engineering
6. Water Resource Engineering
7. Materials Engineering
8. Surveying

Some people who got famous after doing…
