Royal Saxon triangulation

from Wikipedia, the free encyclopedia

The Royal Saxon Triangulation (here with the historical proper name ) is a land survey carried out in the years 1862 to 1890 on the territory of the Kingdom of Saxony with the simultaneous creation of a trigonometric network.

The aim was to precisely record the national territory scientifically and geodetically and to create the basis for the production of accurate maps by defining permanently marketed fixed points . The Grossenhainer baseline was determined as the benchmark .

Network structure

The triangulation network comprised a total of 158 first and second order stations . This made it one of the tightest and most progressive in Europe at the time. The 29 points of the 1st order had a mutual distance of 30 to 50 kilometers (on average 40 km), those of the 2nd order of around 20 km. The 1st order stations were used to measure Central European degrees , while the 2nd order stations were also used for Saxon triangulation.

The surveying network covered around 16,000 km² (today's area of ​​Saxony 18,420 km²). The longest side of the network measures 53 km, on the southern border some network diagonals of up to 60 km in length could be observed over Bohemian territory.

Extension to the meridian arc

Soon after the start of work, it was agreed with Austria-Hungary to connect the triangular network close to the border around the standard Großenhain baseline to the south with the Bohemian surveying network. Due to the Austro-Prussian War that broke out in 1866 , the project stalled for a long time, but eventually even became part of the 700 km long meridian arc Grossenhain-Kremsmünster-Pola .

calculation

general triangle

The position of the measuring points A and B is known, thus also their distance (distance c). The position of point C is to be determined. The angle between line AB and line AC is measured from position A by means of a target disk or theodolite . The angle is also measured from position B. The length of the unknown distances a and b is calculated as follows: a = c * sin / sin and b = c * sin / sin . The intersection of the circles drawn around A and B with radius b and a is position C. Of course, this measuring method requires that all points are freely visible. Many of the mountain peaks used for triangulation at that time, however, were significantly less forested than today and visual connections to other stations also had to be made possible by cutting aisles. Today many of the triangulation pillars' locations are largely overgrown.

The measurement of an angle with a theodolite is, like all optical measurement methods, always fraught with inaccuracy. One will therefore try to carry out the measurements from more than two known points and place the point sought in the middle of the results obtained.

Triangulation columns

The triangulation pillars are listed as technical monuments (totality of the Royal Saxon Triangulation ["European degree measurement in the Kingdom of Saxony"]).

1st order stations

The fixed points are each about 50–60 kilometers away from the nearest located. At the time of the measurement, at least three further stations of the same order were directly observable from each first-order station, i.e. the sightings were clearly visible.

Within the first-order triangular network consisting of 36 stations, a more closely-meshed second-order network with 122 fixed points was established at the same time. The 2nd order points are about 20 km apart.
