Answer #1

Survey can be controlled by all of below options

1)Triangulation surveying is the tracing and measurement of a series or network of triangles to determine distances and relative positions of points spread over an area, by measuring the length of one side of each triangle and deducing its angles and length of other two sides by observation from this baseline.

2)Trilateration, method of surveying in which the lengths of the sides of a triangle are measured, usually by electronic means, and, from this information, angles are computed

3)Traverse is a method in the field of surveying to establish control networks. It is also used in geodesy. Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point.
