Difference between Plane and Geodetic Surveying
|
Plane Surveying
|
Geodetic Surveying
|
|
Curvature of the
earth is not taken in to consideration
|
In this curvature of
earth is considered.
|
|
In plane Surveying,
line joining any two points of triangle formed by any three points is
considered as straight line and plane triangle are assumed to be plane
angles.
|
In geodetic
surveying line joining two points of triangle formed by three points is considered
as curved line of spherical triangle and angles of triangle are considered as
spherical angles.

|
This survey is done
on smaller area less than 250km2
|
This survey is done
on large area greater than 250 km2
|
|
Required accuracy is
competitively low.
|
High accuracy is
required
|
|
Simple methods and
instruments can be used as the required accuracy is low.
|
Very refined methods
and instruments are used.
