THE ROLE GIS IN THE ASSESMENT OF ELECTROMAGNETIC RADIATION ON THE EXAMPLE OF A RESIDENTAL AREA

Today, one of the important tasks that is set before environmental monitoring is to continuously obtain the necessary data on the state of the environment through the use of remote sensing techniques. It should be noted that remote sensing (hereinafter – RS) is used in the technogenic environment of mankind, which directly creates unfavorable conditions, increasing the statistics of the origin of various types of carcinogenic risks. The growing consumption of electric energy leads to the construction and commissioning of new energy facilities, as well as to the construction of high-voltage power lines in the residential environment. An important task in this direction is the establishment of sanitary protection zones, taking into account environmental restrictions, which is aimed at reducing social tension among the population located in the zone of active exposure to the electromagnetic field. Given that low-frequency energy objects, like other man-made objects, are characterized by dynamic characteristics and require constant monitoring of the course of changes in continuous processes, which directly affects the change in the intensity of the electromagnetic field. In turn, the modern information platform allows you to simultaneously conduct environmental surveys to identify carcinogenic risks in the selected area at a specific time by entering the necessary data, which are the main factors in setting the maximum permissible conditions. The development of digital maps based on Arc GIS application programs has a simulation characteristic and allows you to visually assess the dynamics of environmental changes with different variations.

The primary aim of project highlight was to E&M a universally-applicable suite of elements and techniques that allow remote sensing techniques to the E&M-environmental changes and human interventions and the impact of disaster management systems for the period (2010-2015). The framework allows evaluators to monitor changes in a manner that is rapid, independent and reliable. Such a pattern is required to promote contribution and transparency towards a more systematic understanding of the process of E&M. The factors are based on the use of Very High-Resolution Optical Satellite Imagery and have been developed to fit existing change approaches, such as the In-Disaster Needs Assessment-IDNA, and the Affected Cluster Framework. The elements encompass a range of environmental, climate, economic, health, physical and social factors, which can be analysed to provide a holistic representation of the E&M changes process. The paper begins by addressing the need for a E&M framework and by reviewing current guidelines and systems. Which are continuously developed in this case study. Recommendations are made on: 1- How to use disaster management systems; 2- Which elements should be monitored; and 3- How they can be evaluated, drawing on the experience of environmental scientific researcher, and feedback by the evaluators’ academics.

High Voltage Power Lines

Energy objects, installations of high and ultra-high voltage, are considered man-made, dangerous objects in terms of the intensity of the electric and magnetic field distribution, which create ion shells in high-altitude zones and spread a certain radius on the territory of a residential area. In this regard, during the construction and commissioning of low-frequency power facilities, it is necessary to conduct a specific environmental analysis on the selected territory. One of the main sanitary and epidemiological requirements for the construction and commissioning of high – voltage power lines is to take into account changes in the daily and seasonal distribution of electrical loads along high-voltage power lines, which have a continuous dynamic characteristic that increases the level of electric and magnetic field strength. In turn, the development of information support for environmental problems of the territory based on GIS technologies makes it possible to record information about the ecological state of the territory at a specific time and present this state with a set of thematic environmental maps of various territorial or district entities. It should be noted that the above characteristics increase the advantage of geoinformation technologies as an information platform of the database, which will make it possible to obtain data for processing operational analyses and conclusions about the state of the environment around high-voltage power lines.

Ice-free areas cover a small percentage of the land in the South Shetland Islands. However, they are significant as they contain ecosystems highly sensitive to environmental changes and are located within a region affected by global warming. These areas are dominated by periglacial, glacial, fluvial, and coastal processes and landforms, where permafrost is often present. Soil development is observed although vegetation cover is sparse and closely related to the geomorphology. The mapping and monitoring of ice-free areas is important as they are highly sensitive to climate change. The objective of this study was to characterize and map surface landforms in ice-free areas using traditional mapping methods as well as advanced remote sensing techniques. Geomorphological and topographical maps were initially obtained through field measurements and observations, and complemented with existing aerial photography at scales between 1:2000 and 1:25000. Thereafter, satellite-borne data became available and were included in the methodology to further determine the distribution of the landforms. In the Antarctic environment, Synthetic Aperture Radar (SAR) provides the most reliable images as data can be obtained in any weather conditions as well as during the day and night. Fully polarimetric SAR RADARSAT-2 were used to determine seven different terrain classes representing surface landforms in ice-free areas around Maxwell Bay (King George Island). The SAR remote sensing techniques were successfully applied to identify different periglacial, fluvial, glacial, coastal, as well as lithological landforms. Field data from Fildes Peninsula were used to train a supervised classifier to map further areas around Maxwell Bay. In this case, the ice-free areas around Maxwell Bay clearly show the dominance of periglacial landforms and processes. Therefore, these techniques can be used to compare past and future results and to monitor areas affected by changing environmental factors and increasing human activities.

Abstract. With the further acceleration of the new urbanization process, China's urbanization construction has entered a new stage of more standardized and scientific development, which puts forward higher requirements for national land and space monitoring. In view of the rapid changes in looks of our cities, the periodic monitoring methods such as personnel patrolling inspection, public reporting or satellite remote sensing are difficult to meet the needs of full-range, dynamic and precise monitoring. Therefore, it is urgent to establish a new spatial monitoring system to make up for the deficiencies of current urban spatial monitoring. In the article, the authors provide an implementation idea of a space-aerial-ground integrated remote sensing monitoring method system, which integrates various remote sensing techniques and information platform to meet the needs of large-scale urban change cycle monitoring and continuous monitoring of key construction areas Space monitoring provides modern technical support. Some of the techniques in the method system described here have been applied in some regions, which provides a basic platform for regional city monitoring, and have further research and application prospects.

AbstractIllegal extraction of gold has grown to be a problem in many countries, causing the degradation of the environment. The main purpose of this paper is to investigate changes in tree cover and surface pollution. The development of a mine site has been observed and analysed with images acquired from Landsat and the Sentinel missions. The results of the study showed changes in the state of the environment, strongly suggesting the possibility of ongoing pyrite weathering processes and the transportation of clay materials down watercourses, which can cause not only the further deterioration of the environment but also slow down the natural regeneration of the forest. In addition, research has found disturbing changes in vegetation, showing a loss of tree cover in the Amazon Rainforest as high as 17%. The validity of using remote sensing methods to observe the development of individual mining sites and their characteristics was confirmed.
