We have discussed about plane surveying and geodetic surveying before in another articles.

Plane Surveying and Geodetic Surveying
Five major differences between plane surveying and geodetic surveying are given below.

Geodetic surveying
|
- Effect of the curvature of the earth surface is ignored.
- The earth surface is assumed to be plane, i.e. two dimensional.
- Involves smaller areas less than about 260 km2.
- Lower degree of accuracy.
- Done locally by the individual organization

- Effect of the curvature of the earth surface is included.
- The earth surface is assumed to be spherical, i.e. three dimensional.
- Involves larger areas more than about 260 km2.
- Higher degree of accuracy.
- Done by the concerned state or government department.

I am a civil engineering student and i’m very glad to find this civil engineering website for basics. Keep it up man..
Keep it up man
very useful in this website for civil engineers…
Keep it up man
i am student of civil and I want to thank you for this website. It helps me understanding meanings and other things.
Thanks for the inspiration. Let me know if you have any suggestion to make this a better place for the civil engineers.
Am a mining eng student bt this site has been of great help to me…keep it up guys
Pls what are the different geodetic surfaces.?
Keep it up
im a civil engineering student keep up the good work
