This research focuses on a systematic literature review of the geospatial Linked Data (LD) publication at National Mapping and Cadastral Agencies in Europe (NMCA) responsible for land administration. We analysed scientific studies published from 2014 to 2023. Our research aimed to find out the reasons for the relatively slow adoption of geospatial data publication as LD. Therefore, we searched for the most common problems, solutions, and challenges for publishing prioritised data themes in NMCAs. Applied research methodology relies on well-established approaches such as analysing Population Problems, Intervention, Comparison, Outcomes, and Circumstances (PICOC) and backward snowballing. The eligibility process is presented by Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. We analysed nineteen extracted papers and identified twelve key issues from full-text reading. Frequency analyses resulted in the overview of the most frequently published geospatial themes as LD in several European countries. We addressed five research questions and concluded that in addition to systematic support for developing vocabularies and ontologies, trust, awareness, and knowledge about best practices could influence the success of LD publication at NMCAs.

This paper presents the main characteristics of Eutric Cambisols, their productivity potential expressed as land-rating, and their spatial distribution in Slovenia. Differences in soil properties were evaluated among the six predominant groups of Eutric Cambisols; classification was based on the parent material. In addition to individual characteristics affecting soil quality (texture, soil depth, amount of plant available water, pH, base saturation, cation exchange capacity), a comparison of land-rating values between the groups was also performed. We analysed 200 profiles excavated as part of the Slovenian Soil Mapping or other soil surveys conducted by the Center for Soil and Environmental Sciences, Biotechnical Faculty, University of Ljubljana. Our results show that Eutric Cambisols cover 15.5% of the area of Slovenia. Most Eutric Cambisols are on flysch (19.3%, 600 km²), followed by Eutric Cambisols on marl (12.7%, 398 km²). Eutric Cambisols on sandy gravel alluvial sediments, an important soil for crop production, cover 295 km² (9.4%). They have a favourable loamy texture and optimal pH. The flat terrain also contributes to this soil’s highest average weighted land-rating value (70 points). The average weighted land-rating value of all Eutric Cambisols is higher than the average weighted land-rating value of all agricultural and forest land in Slovenia, which is 36 points; this must be considered in spatial planning, as this type of land has a small share and above all, it must be protected from various degradations.

The borders of the cadastral municipalities that are still valid today are, in many cases, based on much older landowners’ borders of feudal lordships. Thus, in central Slovenia, in the forests below Mount Krim, we find the old boundary marks representing today’s cadastral municipality of Preserje, based on the former border between the Carthusia Bistra and the Ig estate from 1726. The main purpose of this paper is to present the current state of the preserved boundary marks along this border. The preserved boundary marks are about 80 cm high, have carved sequential letters, the year 1726 and coats of arms of the Carthusia Bistra and the earls Engelshaus (the owners of the Ig estate at that time). In 1748, this boundary was adopted as the boundary between the Notranjska (Inner) and the Gorenjska (Upper) districts of the Carniola region in the Habsburg Monarchy. As part of the Franciscan cadastral survey in 1823, this border was used as the border of cadastral municipalities, and it has retained this role until today. On the Franciscan cadastral maps, we find eleven locations numbered with the year 1726 and the consecutive letter from B to M. Today, at these locations, we can still find two original boundary marks decorated with coats of arms and the year 1726, two destroyed original boundary marks and three probably later replaced boundary marks without inscriptions and coats of arms. We also examined locations on the even older eastern border of the Carthusia Bistra, on which today mainly only post-war trigonometric points of lower orders can be found; only on the Smrekovec hill under Rakitna did we find another older boundary mark without additional inscriptions or coats of arms.

This article describes the geodetic network of the Urbas landslide. It is the largest landslide in the Koroška Bela region, which, if triggered, can endanger human lives and damage infrastructure. In order to monitor the landslide, a geodetic network was established in the area of the Urbas landslide, on the basis of which the movements of control points can be calculated. After various analyses, only two small areas near the Urbas landslide proved to be stable, so we established four reference points there. In this research we defined the geodetic datum of the geodetic network of the Urbas landslide. The geodetic datum was defined on the basis of four measurement epochs processed with our own software.

The land-rating measures land site productivity based on natural factors, including soil characteristics, climate, relief, and special impacts. The basic unit of administering land rating is the equal land-rating area. The establishment and upgrading took place over several years in the entire territory of Slovenia. The uniform layer of the equal land-rating area of the whole state is administered by the Surveying and Mapping Authority based on the proposal of the individual or ex officio. The uniform layer of equal land-rating area and database of land-rating values are public and used for land valuation purposes and for land management measures.

The beginnings of the agricultural and woodland valuation in Slovenia date back to the time of the Austro-Hungarian state when the cadastral classification of land was established. After 1953, the conditions of land management and taxation in Slovenia changed. Expert groups and individuals prepared proposals of land valuation based on site productivity and the economics of the land management. With the publishing of the rules for soil assessment in 1984, the first professional conditions for a new land evaluation were established.

Spatial analysis of the geographic positions of photos taken by tourists enables the monitoring, presentation, and planning of tourism activities in regard to location. Most photo-sharing websites offer the possibility of geo-tagging the photos to provide geographical information. In this paper, we use the geo-coordinates of photos from the Flickr platform to identify the locations of popular tourist attractions and destinations in Slovenia and analyse the mobility patterns of visitors between them. We analysed samples of 210,643 photos taken by 11,555 different Flickr users over a twelve- year period between 2007 and 2018. The results generally show that Slovenia is not an integrated and homogeneous tourism destination than the eastern part of Slovenia, and that there are individual subsystems of destinations with strong centers.

An analysis of the present-day geodetic marks representing trigonometric points of the 2nd and 3rd order was carried out in the area of Slovenia that was part of the Kingdom of Italy between 1920 and 1947. By reviewing topographies, photographs on hribi.net and sample field surveys, we identified, among the 52 2nd order points, 16 points that had the Italian type of geodetic marks and 6 points with even older types of geodetic marks, dating back to the Austro-Hungarian Monarchy. Among the 407 3rd order points, we identified 68 Italian geodetic marks and 15 even older ones. The so-called Italian type of geodetic mark can be recognised as a concrete pillar with a square or octagonal shape, about 1 m high, with a diameter of 40 to 70 cm. The even older geodetic marks are carved from natural stone. These often have the dual function of being a trigonometric point mark and a land cadastral mark, indicating the boundary of cadastral municipalities. We also investigated the eccentric metal target signals erected in 1996, and those between 1995 and 1997, which were an additional post- consolidation of the existing granite trigonometric marks installed after the Second World War. Finally, we highlight the potential of these old geodetic marks in the design and planning of new measurements in the future.

The Sentinel-2 is a high resolution optical satellite mission, developed by the European Space Agency (ESA) for the European Commission. Currently the mission has two satellites in orbit: Sentinel-2A from 23rd June 2015, and Sentinel-2B from 7th March 2017. Revisit time for this twin constellation is five days. The twin satellites represent a very stable data source, but for the first six operational months (i.e. the second half of the 2015). From the very start of the mission, the Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU) is collecting its own archive of Sentinel-2 data for the extent of the Republic of Slovenia. The data is saved in its original processing state (Level-1C) and in four levels of processing. The archive has now been operating for six full years, which is a good milestone for a statistical overview. We analyse the archive of Sentinel-2 data of Slovenia from several aspects at the country level. A special focus is placed on cloud cover, as only cloud-free data can give an impression of the actual spatial and temporal usability of optical data.
