Документ Green areas state assessment within the urban territories(Scientific Route OÜ, 2022) Shestopalov, Oleksii; Tykhomyrova, Tetyana; Lebedev, Volodymyr; Stadnik, VeronikaThe urbanized environment is a complex heterogeneous system that is constantly changing. In large cities, there is a complex stress effect on living organisms. Different areas of the city may be permanently or temporarily dominated by a cer tain stress factor. Vegetation is a component of urban landscapes, which are natural and artificial objects of various functional purposes. The ecological functions of green spaces include: environmental protection, environmental regulation and aesthetic functions. All these functions play an important role within residential buildings, especially in children’s playgrounds. Various types of damage to green spaces negatively affect their main functions. The susceptibility to damage of woody plants by insects depends on anthropogenic factors of the environment, which lead to the weakening of plants and to the loss of resistance to these types of negative influences. The resistance of plants to diseases often decreases under the influence of transport and industrial pollution in the external environment. The purpose of the study is phytopathological analysis of the green areas state on children’s playgrounds in Kharkiv. Green plantations state assessment methods of urban areas using various technical means are analyzed. Green plantings condition and morbidity analysis using one of the offered methods is carried out. Accord ing to the results of phytopathological analysis, it was determined that 100 % of the species Aesculus hippocastanum L., which grow on playgrounds in Kharkiv, are affected by Cameraria ohridella. Among the bushes, Syringa vulgaris L. and Spiraea L. are the most affected by diseases and pests.Документ Investigation of the observation conditions on the terrain of war operation using GIS technology(НТУ "ХПІ", 2017) Hashimov, Elshan Giyas oğlu; Bayramov, Azad Agalar oğluThe modern geoinformation systems (GIS) have been widely applied in Armed Forces for preparation and control of battle operations, for information providing of tactic activities, for improvement of topographic maps etc. In real situations during war activity the Geography information about situation on the terrain can be ofthen changed. So, in this cause the application of usual maps isn’t effective. Only the modern automated control systems can provide fast changing information documenting. The observation condition is one of the terrain features for providing information about enemy troops position and facilities. This feature helps to detemine the distance of sight between any observation points, the invisibility factors of terrain. It is depended on nature of relief plant cover, human settlements and other objects, also meteorological conditions, influencing on the visibility. As result of correct organization of observation, the obtained data help commander to estimate completely the military operation area and adopt a reasonable deсision. In paper the observation conditions between two points of mountain terrain during battle operation have been investigated using GIS technology. The experiments for estimation of observation situation in mountain terrain has been carried out for one of the chosen region of the Caucasus. The visible and invisible areas have been revealed on the line of sight between two selected oversight points. The invisibility factors have been calculated and studied in depended on camera platform height. The visible and invisivle areas are determined under 0-180° angle in range 17941.16 m. The height profile between observations points and the digital heights model of investigated terrain have been constructed and analysed. At the various heights of camera observation platform the 3D heights models of the visible and invisivle areas have been constructed The invisibility factors between two delected viewpoints have been calculated. It is determined that if the heght of camera platform is increased above-ground level then the invisible area is decreased. ArcGIS software has been used for development and calculation measured results.
