In the last years, there was great interest in the development of tools for an effective evaluation of road transport pollutant-related emissions, especially in the urban areas. This paper represents an innovative approach for identifying criticalities about pollutant emissions associated with road traffic and for defining effective policies in order to decrease pollutant emissions. The proposed tool concerns the development of an emission indicator, a proxy measure, which is useful for the assessment of emission problems, based on the use of GPS (Global Positioning System) instantaneous vehicle speed data. The tool can be considered an innovative and adequate solution in many cases in which the development of a valid and robust traffic simulation model, especially DTA (dynamic traffic assignment) is not available in the medium- and short-term horizon. The methodological process concerns the monitoring of road traffic conditions using GPS data from probe vehicles in combination with the use of GIS (Geographic Information System) for the estimation of an emission indicator. The tool has been tested on a real case study in the city of Cluj in Romania for the NOx emissions. The results show the utility of the tool in supporting policy and decision making, due to its ease of application and consistency, especially in defining critical areas.

“…The resolution of all rasters used for modeling was 15 m, most of which were generated by geoprocessing from the digital terrain elevation model. The following data sources were exploited through digitization and geoprocessing [21,22]: Topographic map at scale 1 : 25,000 Geological map Landslides were incorporated into the model as a set of points representing the centroid of the mapped landslide polygons. After mapping the sample that represents the dependent variable, the data necessary for the geoprocessing of the explanatory variables was acquired.…”

Landslides are a major natural hazard. One of the main causes of landslides is deforestation, doubled by water infiltration caused by heavy rains, torrents, floods, sudden melting of snow. In turn, these latter phenomena are also caused by climate change. Landslides are mostly associated with the downward movement of soil, rocks and organic materials under the direct influence of gravity, which causes instability. The authors investigated the numerous landslides produced on the slopes or at the foot of the Solovan Hill, where Sighetu Marmației Municipality is located. Around 120 locations have been identified, which present these instability phenomena. The paper shows how geomatics and geoinformatics technologies can be effectively used in analyzing the evolution of landslides (initiation, development, accentuation, presence of a danger which is triggered suddenly). These analyzes were carried out during the three years of research, respectively, 2020 - 2022. The paper presents a case study for one of the most serious situations, in which a landslide on Valea Cufundoasă street, on the slope belonging to the Solovan Hill, produced the complete destruction of a household in the year 2000.

Landslides are a significant geological phenomenon with the potential for catastrophic consequences. There are numerous potential causes of landslides, including both natural and man-made ones. Their growing frequency raises alarm due to the often catastrophic consequences of these events. The monitoring of regions prone to landslides is a multifaceted undertaking that involves the use of several technologies and approaches, such as geospatial technology and modeling. The primary objective of this work is to construct a spatial analysis model for a region in north-western Romania that is susceptible to landslides. A case study was conducted to estimate the susceptibility of landslides in a monitored region located near Sighetu Marmației, Romania. To achieve this objective, a combination of several technologies and approaches were used, such as remote sensing, land surveying, aerial photogrammetry, geographic information systems, and spatial modeling. The research region underwent landslide susceptibility evaluation by processing geo-information data using Geographic Information Systems (GIS) and developing a prediction model based on the MaxEnt (Maximum Entropy) approach. The research’s distinctive contribution is integrating geo-information data acquired from the hazardous site utilizing geomatics methods into a novel geo-monitoring system. The research offers valuable insights into the monitoring of landslides, adding to the current body of literature by introducing an expanded paradigm. The study’s theoretical and practical implications might be valuable for professionals, local authorities, emergency response agencies, and other parties involved in mitigating the danger of landslides.
