This paper describes in detail the applicability of the developed ground-penetrating radar (GPR) model with a kinematic GPR and self-tracking (robotic) terrestrial positioning system (TPS) surveying ...setup (GPR-TPS model) for the acquisition, processing and visualisation of underground utility infrastructure (UUI) in a real urban environment. The integration of GPR with TPS can significantly improve the accuracy of UUI positioning in a real urban environment by means of efficient control of GPR trajectories. Two areas in the urban part of Celje in Slovenia were chosen. The accuracy of the kinematic GPR-TPS model was analysed by comparing the three-dimensional (3D) position of UUI given as reference values (true 3D position) from the officially consolidated cadastre of utility infrastructure in the Republic of Slovenia and those obtained by the GPR-TPS method. To determine the reference 3D position of the GPR antenna and UUI, the same positional and height geodetic network was used. Small unmanned aerial vehicles (UAV) were used for recording to provide a better spatial display of the results of UUI obtained with the GPR-TPS method. As demonstrated by the results, the kinematic GPR-TPS model for data acquisition can achieve an accuracy of fewer than 15 centimetres in a real urban environment.
Prazgodovinski kompleks Cvinger pri Dolenjskih Toplicah leži na strateški točki na prehodu med Dolenjsko in Belo krajino. Tukaj odkrite najdbe so imele pomembno vlogo pri opredelitvi mlajšega ...halštatskega obdobja v jugovzhodnih Alpah. Prav tako pomembno je odkritje železarsko-talilniškega območja.
V zadnjih letih pa je bil Cvinger predmet interdisciplinarnih raziskav, ki so povezale sodobne tehnike daljinskega zaznavanja, kot so zračno lasersko skeniranje in geofizikalne meritve, s tradicionalnimi arheološkimi metodami. Rezultati so pripeljali do novih dognanj o celotnem kompleksu, vključno z natančnejšo datacijo talilniškega območja, pridobljeno z metodo arheomagnetnega datiranja.
This paper describes in detail the development of a ground-penetrating radar (GPR) model for the acquisition, processing and visualisation of underground utility infrastructure (UUI) in a controlled ...environment. The initiative was to simulate a subsurface urban environment through the construction of regional road, local road and pedestrian pavement in real urban field/testing pools (RUTPs). The RUTPs represented a controlled environment in which the most commonly used utilities were installed. The accuracy of the proposed kinematic GPR-TPS (terrestrial positioning system) model was analysed using all the available data about the materials, whilst taking into account the thickness of the pavement as well as the materials, dimensions and 3D position of the UUI as given reference values. To determine the reference 3D position of the UUI, a terrestrial geodetic surveying method based on the established positional and height geodetic network was used. In the first phase of the model, the geodetic network was used as a starting point for determining the 3D position of the GPR antenna with the efficient kinematic GPR surveying setup using a GPR and self-tracking (robotic) TPS. In the second phase, GPR-TPS system latency was quantified by matching radargram pairs with a set of fidelity measures based on a correlation coefficient and mean squared error. This was followed by the most important phase, where, by combining sets of “standard” processing routines of GPR signals with the support of advanced algorithms for signal processing, UUI were interpreted and visualised semi-automatically. As demonstrated by the results, the proposed GPR model with a kinematic GPR-TPS surveying setup for data acquisition is capable of achieving an accuracy of less than ten centimetres.
We applied an interdisciplinary approach to analyze the late Quaternary activity of the Sava Fault in the Slovenian Southern Alps. The Sava Fault is an active strike-slip fault, and part of the ...Periadriatic Fault System that accommodated the convergence of Adria and Europe. It is one of the longest faults in the Southern Alps. Using high-resolution digital elevation models from lidar and photogrammetric surveys, we were able to overcome the challenges of assessing fault activity in a region with intense surface processes, dense vegetation, and relatively low fault slip rates. By integrating remote sensing analysis, geomorphological mapping, structural geological investigations, and near-surface geophysics (electrical resistivity tomography and ground penetrating radar), we were able to find subtle geomorphological indicators, detect near-surface deformation, and show distributed surface deformation and a complex fault pattern. Using optically stimulated luminescence dating, we tentatively estimated a slip rate of 1.8 ± 0.4 mm/a for the last 27 ka, which exceeds previous estimates and suggests temporal variability in fault behavior. Our study highlights the importance of modern high-resolution remote sensing techniques and interdisciplinary approaches in detecting tectonic deformation in relatively low-strain rate environments with intense surface processes. We show that slip rates can vary significantly depending on the studied time window. This is a critical piece of information since slip rates are a key input parameter for seismic hazard studies.
Kuruçay Höyük can be considered a key site for our understanding of Late Prehistory in southwest Turkey and above all, the poorly known Late Chalcolithic (4200-3100 b.c.). Until now, limited research ...has been conducted on the relationship between the excavated site and its surrounding. This article discusses the Late Chalcolithic results of an integrated survey in the vicinity of Kuruçay Höyük in the Burdur Plain. Drawing upon these results, this paper illustrates that the site was far from an isolated feature during the 4th millennium b.c. The picture that emerges is one of a differentiated settlement system consisting of both larger höyük/tell settlements (like Kuruçay Höyük) and smaller sized, possibly short-lived, flat settlements. These results are further contextualized within the developments that took place in the region during the Chalcolithic, which seem to have opened the door for communities to become more complex during the Early Bronze Age.
Glaciokarst depressions are major glacigenic depocenters in the Dinaric mountain karst areas and often store important information about the timing and nature of glacial processes and paraglacial ...sediment reworking. This study focuses on Praprotna draga, which is one of the largest glaciokarst depressions in the Snežnik Mountain (Dinaric karst), with an area of ~3.4 km2 and a maximum depth of 140 m. The western slopes of the depression are characterized by undulated moraine morphology and alluvial fans are filling its entire floor. We present the results on the thickness, origin and age of the sediment infill using a complementary geomorphological, sedimentological, geophysical and dating approach. Distribution of moraines point to two glacial advances that were associated with two main alluvial fan aggradation phases recognized using the electrical resistivity tomography measurements. The youngest alluvial deposits were sampled for cosmogenic 36Cl analysis using amalgamated carbonate pebbles. The depth profile of 36Cl concentrations suggests an age of 12.3 ± 1.7 ka when assuming a likely denudation rate of 20 mm ka−1. Since the existence of the Younger Dryas glaciers in the study area is climatically difficult to explain, we tentatively propose that the youngest alluvial deposition in Praprotna draga took place after the glacier retreat during the paraglacial period. Our findings suggest that the time window of paraglacial adjustment in the Snežnik Mountain was brief and likely conditioned by quick recolonization with vegetation and inefficient surface runoff on deglaciated karst terrain.

Najdišče Kleinklein pri Großkleinu z okolico v dolini reke Solbe (Sulm) je že skoraj 175 let sinonim za eno najslavnejših najdišč iz starejše železne dobe v Evropi. Najdbe, kot so bronasta maska in ...roke, zvončasti oklepi in bronaste posode s punciranim okrasom, sodijo med najpomembnejše eksponate arheološke zbirke v Joanneumu. Leta 2010 so sodelavci Joanneuma začeli nove raziskave arheološke krajine v porečju reke Solbe (Sulm), ki obsegajo analize lidarskih posnetkov in zračnih fotografij, geofizikalne raziskave, terenske izmere ter arheološka izkopavanja z arheobotaničnimi in arheozoološkimi analizami. V okviru teh raziskav so leta 2015 ob rigolanju na južnem pobočju Burgstallkogla pri Großkleinu odkrili in raziskali zgorelo ruševino stavbe iz starejše železne dobe. S tem odkritjem so pridobili nove podatke o načinu gradnje na Burgstallkoglu. Od leta 2017 se posvečajo raziskavam okoliške krajine, še posebej na približno 4,5 km zračne črte oddaljeni utrjeni naselbini na Königsbergu pri Heimschuhu.
The hill of Panorama in Ptuj is one of the most important areas of Roman Poetovio. Chance finds and small-scale excavations in the past centuries have revealed the existence of significant ...archaeological remains that included buildings with numerous rooms and objects dedicated to a variety of deities, the remains of a sanctuary dedicated to the Nutrices, an Early Christian church, an aqueduct and a cemetery. The geophysical investigations have revealed the urban design with a rectilinear grid of streets and building plots.The first few chapters of the book present the history of archaeological research on Panorama, the analytical approaches and the geophysical investigations with the methods employed and the final results. The main chapters correlate the archaeological data of differing quality and nature (chance finds, rescue excavations, old and modern archaeological investigations, geophysical surveys) and locate them with a series of plans. The comprehensive overview is supported by a Catalogue of stone monuments that presents the basic data, descriptions, bibliography, commentary and photographs of the stone objects recovered on Panorama.
U provedenome terenskom pregledu lokaliteta Kalinovac – Hrastova greda 1 prikupljeni površinski nalazi ukazivali su da se na ovome nalazištu odvijala neka aktivnost povezana s proizvodnjom željeza, ...vjerojatno tijekom srednjega vijeka. S ciljem jasnijega definiranja karaktera samog nalazišta, pristupilo se neinvazivnim, geofizičkim istraživanjima u kojima su primijenjene dvije najrelevantnije metode za ovaj tip lokaliteta: magnetometrija i mjerenje magnetskoga susceptibiliteta. Provedenim istraživanjima, u kojima su obje metode pokazivale slične rezultate, potvrđeno je postojanje ostataka srednjovjekovnoga naselja te nekih željezarskih aktivnosti na najvišem dijelu, blagim padinama i podnožju manjega uzvišenja. Vanjske granice nalazišta sasvim su jasno definirane, dok je unutarnja raspodjela i namjena objekata ostala nejasna, pa se pretpostavlja da se arheološki ostaci u najvećoj mjeri danas nalaze u sloju humusa sa slabije očuvanim dijelovima odmah ispod razine oranja, što će biti jasnije nakon planiranih arheoloških iskopavanja.
Tijekom travnja te kolovoza 2018. godine Institut za arheologiju je u suradnji s tvrtkom Gearh d.o.o. iz Maribora proveo geofizička istraživanja na lokalitetu Hlebine – Svetinjski breg. Lokalitet je ...snimljen georadarskom, magnetnom i metodom geoelektrične tomografije. Provedenim istraživanjima ustanovljen je točan položaj crkve i groblja te njihova ogradna zida. Osim sakralnog kompleksa uočeni su i tragovi drugih arheoloških struktura te je potvrđen potencijal nalazišta i prikupljeni su svi potrebni podaci za buduća ciljana arheološka istraživanja.
