4. What techniques can be used in height measuring?
5. What is triangulation, trilateration and transverse survey?
6. How is the vertical control established?
7. What are the most common techniques used in surveying?

Task 4. Define whether the following statements are true or

false and translate them. Correct the false ones according to
the text.

1. Measurements of distances, directions and height can be
undertaken in surveying methods.
2. Transverse survey measures the angles of a series of

overlapping triangles, polygons, or quadrilaterals.
3. The vertical control network is established by using differential
leveling.

4. Radio compass permits the precise measurement of elevational
differences between known and unknown points on the Earth’s
surface.
5. Inertial systems is a gyro stabilized platform that starts at a

point of known position and elevation.
6. LIDAR uses stereographic pairs of photographs to indirectly

measure objects on the ground.
7. Theodolite is used for measuring angles and distances and for
calculating positions and heights.
