It is created by rotating an ellipse around the shorter polar axis to match the Earth's actual shape. The purpose of control surveys is to provide a uniform framework of reference for the coordination of all surveying activities within a given area. The following documents may have relevance to the application of this Guideline. It is essential to rectify the location values by arranging ground control points (GCPs) appropriately to improve the accuracy of UAV-based 3D topographic maps of earthwork sites.

Indirect Freely positioned the instrument hence every survey points should be at appropriate sight from the instrument. Method of control survey in which a network of triangles is used as in triangulation system. Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them. Closed traverses yield adequate accuracy for property boundary surveys, provided that an established control point is nearby. The methods of triangulation require a maximum number of precise angle measurements . Often, less accurate methods can be used for this work than for water-level recording stations, although the techniques are common. The shape of the triangles is important as there is a lot of inaccuracy in a long skinny triangle, but one with base . Use a minimum of three known horizontal control points and four known vertical control well disbursed throughout the network. It is essential to rectify the location values by arranging ground control points (GCPs) appropriately to improve the accuracy of UAV-based 3D topographic maps of earthwork sites. It consists in finding vertical and horizontal controls of the points which lie on the selected contour line. The horizontal control consists of reference marks of known plan position, from which salient points of designed structures may be set out. A surveyor establishes the horizontal control of that point using his instruments. Geodetic surveying is the responsibility of the national surveying and mapping organization, which undertake geodetic surveys, using precise instruments and surveying Theodolite traversing is used to compute the area of a traverse.
