As we all know, Geodetic surveying and Plane surveying comes under the primary classification of surveying.
In geodetic surveying, the curvature of the earth is taken into account while taking surveying. In this surveying conducted a larger area. Geodetic surveying is mainly conducted to determine the precise positions on the earth surface. It is also called as Trigonometrical surveying.
In-plane surveying, the curvature of the earth is ignored because surveying is conducted in small areas. The degree of accuracy is low as compared to Geodetic surveying.
