We present a study on the preservation rate of geodetic marks in national trigonometric networks. We examined the situation in the forested area of Menišija and in the area of Žužemberk, which we divided into forested and rural parts. In the Menišija area, 27 trigonometric point locations were checked in the field, and in the Žužemberk area, 92 trigonometric point locations were checked. The percentage of preserved trigonometric points of II, III and IV order and of photogrammetric reflection points (VIII order) was checked. We found that the proportion of preserved trigonometric marks is 78% in the Menišija area and 71% in the forested part of the Žužemberk area, while in the rural part of the Žužemberk area the proportion is lower, i.e. 46%.

This paper presents the results of the targeted research project V2-1924: “Permanent geodetic marks as a basis for the high-quality performance of the geodetic profession”, in which we studied permanent geodetic marks from the period of classical geodetic surveying. In order to identify interesting geodetic marks, we interviewed seven experienced professionals. A sample collection of significant geodetic marks was compiled in which the proposals were evaluated in relation to all three of the above-mentioned meanings.

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.

Participants of this project Miran Kuhar (FGG), Bojan Stopar (FGG) and Mihaela Triglav Čekada (GI) participated as the editors on the 25th meeting of the Slovenian Association for Geodesy and Geophysics (SZGG), which took place on 30 January 2020 at the Faculty of Civil Engineering and Geodesy of the University of Ljubljana. Miran Kuhar (FGG) was the main organizer of the conference and the main editor of the conference proceedings. With the organization of the SZGG conference, we are expanding the innovations from the geodesy among other professions participating in this conference. These are meteorologists, hydrologists, geographers and others.
