The sensors were built with open-source components (Raspberry PI). The software is running, and the counting data is collected and analysed via an internet portal (www.telraam.com). The Telraam sensor counts pedestrians, cyclists, cars and freight/heavy vehicles using the images provided by the device sensor and the analysis performed by the “Raspberry Pi” (a small computer on which the device is based). The sensor software uses the size and speed of the passing object to determine and classify the different vehicles. The classification is based on the average observed full value and the axis ratio of each observed object (which meets a set of criteria that helps filter out any movement in the field of view that should be associated with road users). The five traffic sensors camera is mounted directly on the inside of the window glass facing the street at varying distances from the road (from 3 to 15 meters), where they count traffic only during daylight hours, update their count every hour and separate car traffic by direction.

The Franciscan cadastral maps comprehensively cover the entire territory of the Austro-Hungarian Empire. They are a trustworthy source of historical land-use data and information regarding past urban-planning concepts, especially due to their high geometrical precision. Studying and analysing historical land use makes it possible to reconstruct the historical cultural landscape, which is itself a significant element of cultural heritage. In studying historical maps, the most widely used analytical approach is the comparative method. Matching and overlaying historical and contemporary map data makes it possible to see and analyse changes in land use. This technique has been widely adopted and is now well established, but advanced technologies like high-resolution Lidar terrain data offer new opportunities. It is postulated that especially in rural areas, unlike land use, the terrain has not changed significantly, and the combinati...

However, in most cases, the planning of terracing in practice remains experience-based, which is no longer effective from an agricultural, geological, and hydrological point of view. The usual method of building terraces, especially terraces with earth risers, is therefore outdated, and a new method must be found for planning and building terraced areas. In addition to geographical information system (GIS) tools, parametric design tools for planning terraced landscapes are now available. Based on the design approaches for a selected plot in the Gorizia Hills in Slovenia, where we used a trial-and-error method, we improved previous results by defining a model using a computer algorithm that generates a terraced landscape on a selected slope depending on various input parameters such as the height of the terrace slope, the inclination of the terrace slope, the width of the terrace platfor...

For the definition of the algorithm we used the visual program tool Grasshopper. By changing the values of the input data parameters, the algorithm was able to present combinatorial simulations through a variety of different solutions with all the corresponding statistics. With such results it is much easier to make a conscious decision on which combination of parameters is optimal to prevent landslides, plan adequate drainage, and control soil movements when building terraces. The controlled slope intervention is further optimized by the introduction of a usage index (Tx), defined as the quotient of the sum of all flat areas (terrace platforms) and the total area of the plot.

The Franciscan cadastral maps comprehensively cover the entire territory of the Austro-Hungarian Empire. They are a trustworthy source of historical land-use data and information regarding past urban-planning concepts, especially due to their high geometrical precision. Studying and analysing historical land use makes it possible to reconstruct the historical-cultural landscape, which is itself a significant element of cultural heritage. In studying historical maps, the most widely used analytical approach is the comparative method. Matching and overlaying historical and contemporary map data makes it possible to see and analyse changes in land use. This technique has been widely adopted and is now well established, but advanced technologies like high-resolution Lidar terrain data offer new opportunities. It is postulated that especially in rural areas, unlike land use, the terrain has not changed significantly, and the combination of detailed three-dimensional terrain data and historical land use can yield novel views on the man-made landscape of this era. The methodology presented can generate other interpretations of the available data. A combination of new technologies and techniques can provide an accurate virtual historical view and comparison with the same location in the present. The research presented offers fresh insights into what the cultural landscape looked like in the past and what actions can be taken to preserve it in the future.

The research goals are to present the possibility of using multiple-criteria models of evaluation in selection of spatial solutions, to implement (realise) the model in Rhino 3D environment, to test the model on the example of an actual architectural competition
and to test and compare three methods of multiple-criteria evaluation for suggested spatial solutions. To check the
hypothesis and the research questions, documentation from a closed, public, project, open, anonymous, single-stage architectural competition was selected. The selected solutions were evaluated by three methods. For all the selected multiple-criteria methods we can establish that they are highly subjective, not too accurate and as such inappropriate for the evaluation of solutions to the spatial problem. According to certain criteria, the PMI (“plus/minus/implications”) method of multiple-criteria decision making has proven to be the best or the most useful method among the analysed ones.

The boundaries of terraced areas in Slovenia cannot be clearly defined without the help of a field survey even when the configuration of the terrain makes surveys difficult. The segmentation of point cloud data into various classes of foliage, ground, buildings, and so on makes previously hidden earthwork structures (including abandoned terraces) instantly recognizable. The conceptual shift is that the LIDAR slope analysis layer is more revealing and instructive for discovering terraces areas than orthophoto images ever were. Although LIDAR data are a new tool in the search for terraced areas, orthophotos remain important but are nevertheless only a contextual aid. A quantitative comparison between the old and new methods shows no difference in three pilot areas, shows only a minor difference in two cases, and reveals major differences in three pilot areas. The quantitative differences in some of the pilot areas are compelling. However, the most significant feature of the new method is its reliability for detecting the exact boundaries of terraced areas. LOCALIZZAZIONE DI AREE TERRAZZATE IN SLOVENIA: RILEVAMENTO ATTENDIBILE CON IL LIDAR SINTESI I dati prodotti con la tecnologia LIDAR si presentano come un preciso strumento interpretativo, nuovo e senza precedenti nella localizzazione di paesaggi terrazzati. In Slovenia, l'identificazione dei confini di aree terrazzate ri-chiede sistematicamente l'aiuto di indagini sul campo, anche quando la configurazione del terreno rende tali indagi-ni difficili. Con la segmentazione dei dati a nuvola di punti nelle categorie del fogliame, suolo, edifici ecc. le strutture di terrapieno precedentemente nascoste (incluso terrazze abbandonate) risultano subito riconoscibili. L'innovazione concettuale del LIDAR sta nel fatto che il suo livello delle analisi di pendenze è più rivelatore e informativo per la localizzazione di terrazze di quanto non lo siano mai state le immagini ortofoto. Ciò non toglie che le ortofoto riman-gono un aiuto importante nella ricerca di aree terrazzate, anche se meramente contestuale. In tre delle aree pilota in cui sono stati eseguiti i rilevamenti, i risultati non hanno evidenziato nessuna differenza quantitativa tra il vecchio e il nuovo metodo, in due aree si è osservata una minima divergenza, mentre in tre aree pilota le differenze sono state notevoli, in alcuni casi straordinarie. Comunque, la funzionalità distintiva del nuovo metodo sta nell'attendibilità della localizzazione dei precisi confini di aree terrazzate.
