Engineering geodesy

Geodesy is one of the oldest technical sciences. Recently, it has been experiencing extraordinary development both in science and in practice. The development of geodesy is closely related to the development of other sciences and new technologies, as well as to society's needs for quality spatial data. For this purpose, there is interdisciplinary cooperation between different professions. The field of geodesy today includes lower and higher geodesy, photogrammetry, remote sensing, satellite geodesy, geodetic records, urban and rural planning, spatial planning, geographic information systems and cartography. The name geodesy is composed of the Greek words 'geo', which means Earth, and 'desis' which means to measure. At its core, geodesy therefore deals with determining the position.

Lower geodesy mainly involves measuring individual smaller parts of the earth's surface and presenting them on plans and maps. The works of lower geodesy also include the works of engineering geodesy and cadastral surveying. Engineering geodesy is mainly concerned with the transfer of designed objects to nature (staking out objects) and monitoring objects throughout their lifetime, while cadastral surveying is concerned with determining the boundaries between ownership plots and ownership of objects.

Higher geodesy deals with the measurement of the Earth as awhole. by determining the shape and dimensions of the Earth as a celestial body, i.e. by observing geodynamic phenomena, which include movements of the earth's crust, tides and the movement of the earth's pol.

Photogrammetry and remote sensing deal with the measurement of the earth's surface, usually from the air, and the creation of graphic representations of this surface.

Cartography deals with the creation, maintenance and reproduction of maps. Locating spatial data requires their treatment in a coordinate system. For this purpose, global and national networks of geodetic points have been developed all over the Earth.

In the context of the use of geodesy in the construction industry, the textbooks mainly focus on lower geodesy; geodetic field measurements, the basics of mapping and real estate records are also described. The textbook is designed on a theoretical basis and the practical application of individual measuring methods for the needs of studying engineering geodesy in the professional construction programs of universities and is prepared in accordance with the knowledge catalog for this subject. The investor guides the student through the entire textbook, who has unsolved questions in each chapter and therefore asks them to the students. Questions of this type are marked with the symbol . Each chapter also contains additional repetition of knowledge (Repetition) and guidance to students for further deepening of the professional field (More information about this chapter can be found in), which the chapter deals with. Given that we are in the age of electronic communications, the textbook directs students to find additional resources and visual material for each topic that better clarify the content of each chapter. In doing so, the student must be able to separate the wheat from the weeds.
