In this paper, the historical development context of the trigonometric network point types in Slovenia from 1810 onwards is presented. Examples of different trigonometric point types still seen in the field are shown, with regard to the institution that carried out the field marking of the specific state trigonometric network. The city trigonometric network of Ljubljana, which was established in 1955–1956, is also presented. Furthermore, triangulation and comparator bases are mentioned as well, which remain marked with permanent pillars. As examples of the oldest still-standing trigonometric points, the following are mentioned: 303 Veliki Javornik (2nd order) with the engraved year 1823 and 329 Limberk (2nd order) with the engraved year 1903.

For using urban mapping in the interwar period in European countries, a network of check points was formed applying the triangulation method, i.e. by means of the network of evenly arranged points shaping triangles. It was first designed for Kaunas in 1924 using 36 check points fixed on a locality and measured by engineer Z.Bačelis. The network used to satisfy the territories of the former areas of Vilijampolė, Aleksotas, Žaliakalnis, Naujamestis and Ž. Šančiai. When Kaunas became a temporary capital, the city grew rapidly. The ongoing triangulation did not fit in due to the following reasons: a big part of check points in the locality had not been preserved, the city expanded twice as much and due to the applied tools, the accuracy of check points remained unsatisfactory. The new network was designed so that to satisfy one check point, on average, 1 sq. km of the city area should be applied and ensure limited accuracy of 10 cm of the approved check points. The benefits of implementing the second triangulation of Kaunas city are attributed to the experts of the Measurement division of the City Municipality - the director J.Deksnys and his deputy J.Ašmonas.
