Question

Compare and contrast between plane surveying and geodetic surveying as classifications of surveying.

a) Plane surveying is used for small-scale mapping, while geodetic surveying is for large-scale mapping.

b) Plane surveying is suitable for local areas, while geodetic surveying covers large regions and considers the Earth's curvature.

c) Both plane and geodetic surveying are used interchangeably for any mapping purposes.

d) Plane surveying is more accurate than geodetic surveying.

Answer 1

Plane surveying is used for small-scale mapping, while geodetic surveying is for large-scale mapping. Plane surveying is suitable for local areas, while geodetic surveying covers large regions and considers the Earth's curvature. Geodetic surveying is more accurate over long distances.

Step-by-step explanation:

Plane surveying and geodetic surveying are two classifications of surveying that differ in their purpose and scale of mapping.

Plane surveying is used for small-scale mapping, such as mapping of local areas or land subdivisions. It assumes that the Earth's surface is flat and does not consider the curvature of the Earth. Since it does not account for the Earth's curvature, plane surveying results in lower accuracy over large distances.

Geodetic surveying is used for large-scale mapping, covering larger regions or even the entire Earth's surface. It takes into account the Earth's curvature and uses spherical trigonometry and geodesy to accurately measure distances and angles. Geodetic surveying is necessary for projects that require high accuracy, such as national boundary surveys or the construction of large infrastructure.
