Analysis of Shading in the Preselection Process of Lands for the Construction of Photovoltaic Parks

Author(s): Tudor Borșan,George Emanuel Voicu / Language(s): English Issue: 34/2023

Through this paper, we aim to showcase the ways in which we can harness elevation models for studying shading within the GIS environment. This goal is tied to the project in which my colleague, George Emanuel Voicu, and I have participated, a project involving the acquisition of topographic data and spatial analyses to highlight shading studies – crucial aspects in selecting the most suitable areas for constructing a photovoltaic park. The initial phase involves gathering precise topographic and geospatial information, including climate data and celestial positioning. These acquired data are then integrated into Geographic Information Systems (GIS) to provide a comprehensive view of the terrain and environmental factors that could influence shading. The subsequent step involves using advanced simulation and modeling technologies to analyze the behavior of solar radiation under various conditions and at different time intervals. This stage is pivotal in generating accurate shading models that delineate critical areas with shading potential and their effects on solar panels.

Improving Human Living Using Bathymetric Methods

Author(s): Lavinia Ramona Chișbac,Silvia Alexandra Dreghici / Language(s): English Issue: 34/2023

The continuous technological improvement in bathymetric equipment, positioning capacity, data processing, as well as the development of new ways of depth determinations and exploring the submerged relief, have been noticed in recent years. There are multiple techniques, more or less precise, used for depth surveying. Among these, acoustic and radio bathymetry are most widely used. Survey systems can be autonomous or mounted on various platforms and also can provide different accuracies. If GNSS data is correlated with the bathymetric survey systems, the results have improved accuracy. Additionally, optical methods (based on active or passive sensors) can be used for depth surveys. Comparing to topography, even despite the multiple bathymetric methods and their usage, underwater still remains uncertain or unknown. Though, administrative decisions based on bathymetric data include maritime or nautical navigation safety, coastal spatial planning, environmental protection, underwater exploration, research and monitoring, and not least underwater resources exploitation. A better knowledge and understanding of the underwater relief could lead human to reduce water pollution, and therefore, to a better life.

Geoinformation modeling of radioactive contamination of territories on the example of mines of the “ShidGSK” mining and processing plant

Author(s): N. Neposhyvailenko,V. Gulyaev,Y. Gritsan,O. Huba / Language(s): English Issue: 1/2024

The aim of the study was to model the territorial distribution and statistical assessment of migration through the trophic chain of naturally occurring radionuclides released into the environment as a result of uranium ore mining. Statistical, geoinformation and experimental research methods were used in the study. Interpolation of the results of volumetric activity of natural radionuclides in environmental components and development of spatial models of their territorial distribution were performed using the ArcGIS software; statistical processing of modelling results and development of mathematical models of migration of natural radionuclides between environmental components were performed using ArcGIS Geostatistical Analyst software. The paper substantiates the choice of the method of geostatistical modelling of the territorial distribution of volumetric activity of natural radionuclides 234U, 238U, 210Po, 210Pb, 226Ra in soils and plants, which allows modelling the values of probabilistic indicators of radioecological contamination in the absence of a sufficient array of initial actual research results. Based on the analysis of the data obtained, the methodology of mathematical modelling of migration of natural radionuclides between soil and plant parts was further developed, which will facilitate consideration of the specifics of migration of natural radionuclides through the trophic chain and help in determining the level of radioecological hazard to the environment. The developed territorial models allow one to obtain stochastic data for their further analytical processing and visualizing radioecological hazard zones. Based on the developed models, zones of increased radioecological hazard within the existing sources of radioactive contamination were identified.
