                        Text 1. Principles of Surveying. Measurement Technology

                        Surveying is the art and science of measuring the surface of the
                  Earth  and  its  features.  In  general,  there  are  three  types  of

                  measurements, that can be undertaken in surveying methods:
                        - Distance        measurements.            Different        instruments         and
                  technologies can be used for measuring distances: mechanical tools,

                  electronic measuring instruments (EDM), GPS, Remote Sensing (RS)
                  techniques, etc.
                        - Directions  are  measured  by  a  magnetic  compass,  theodolite,
                  gyrocompass, radio compass, RS, etc.

                        - In height measurements the following techniques can be used:
                  leveling, GPS, inertial system, RS, etc.
                        Survey measurements can be divided into two categories:

                        1. Horizontal  surveying  can  be  conducted  using  the  following
                  methods:
                                                             106
