The beginning
Four thousand years ago, the concepts of math were basic, yet the Egyptians were able to achieve wonders. They used the predecessors of modern surveying instruments to engineer many feats, from canals to pyramids. An ancient Egyptian survey crew used measuring ropes, plumb bobs, sighting instruments, and leveling instruments.
History
According to ancient legend pictures found in Egyptian tombs show scribes and their assistants carrying ropes tied with equally-spaced knots. Speculation is that the ropes were used to create right triangles to establish boundaries after the yearly flooding of the Nile which helped build the pyramids.
History
Civilizations developed their own surveying solutions as well as needed instruments. One of the inventions was “the groma” which was developed in Mesopotamia. This patent was mainly used by Greeks and Romans. It comprised a vertical staff with horizontal cross-pieces mounted at right angles on a bracket. Each cross piece had a plumb line hanging vertically at each end. It was used to survey straight lines and right angles, hence squares or rectangles. They were stabilized on the high ground and pointed in the direction it was going to be used.
History
Geodesy works in Lithuania began in the 16th century. during the Vlach reform1790-1800 geodetic plans of Kaunas and Vilnius were drawn up. In 1924 Lithuania joined the Geodetic Commission of the Baltic States, triangulation of Lithuania was carried out, topographic maps were made.
The present
A lot of geodetic instruments and new geodetic technologies have been created, which are fundamentally different from traditional ones. In previous years, each type of measurement had its own type of instrument: for the angular measurements, the theodolite, for high-altitude measurements - a level, for linear measurements - a tape measure and rangefinder. Each device, depending on the intended use, had its own accuracy characteristics. Over time, science...
