Preparation of the archive photodocumentation data is an important step in information processing for numerous scientific and non-scientific research. For scientific research it can be exploration of phenomena such as: soil erosion, landslide, forest changes and vegetation cover, urban changes related to settlements, etc. Further data analysis can provide information about nature and trend of the problem, as well as conclusions for taking preventive and corrective measures. This paper emphasizes presentation of data preparation method from the Military Geographical Institute photodocumentation archive of aerial photogrammetrical images. The paper also contains the part conected with spatial database model of aerial films.
The paper presents geoecological evaluation of the city of Loznica for the purposes of sports and recreational tourism based on quantitative method of diversity, V-Wert Method. Using the GIS tool by the quantitative method, the criteria of natural components (relief, forest, water surface and climate) are evaluated for the analyzed area. In the proposed method, the climate factor was supplemented by the analysis of the bioclimatic index Universal Thermal Climate Index (UTCI). When the evaluation was completed, the final results were obtained based on which the degrees of convenience of different parts of the analyzed area have been presented. Out of the total analyzed surface, which amounts to 705 km 2 , favorable surfaces comprise 21 km 2 (2.98%), and very favorable surfaces comprise 33 km 2 , i.e. 4.68% of the territory. The largest area consists of conditionally favorable terrains-333 km 2 (47.23%). Since one of the basic strategic priorities of the City of Loznica is improvement and development of sports and recreational tourism, the aim of this analysis is to emphasize the potential of the mentioned area in terms of general suitability of the terrain for the development of this type of tourism.
The urban microclimate is gradually changing due to climate change, extreme weather conditions, urbanization, and the heat island effect. In such an altered environment, outdoor thermal comfort can have a strong impact on public health and quality of life in urban areas. In this study, three main urban areas in Serbia were selected: Belgrade (Central Serbia), Novi Sad (Northern Serbia), and Niš (Southern Serbia). The focus was on the temporal assessment of OTC, using the UTCI over a period of 20 years (1999–2018) during different seasons. The main aim is the general estimation of the OTC of Belgrade, Novi Sad, and Niš, in order to gain better insight into the bioclimatic condition, current trends and anomalies that have occurred. The analysis was conducted based on an hourly (7 h, 14 h, and 21 h CET) and “day by day” meteorological data set. Findings show the presence of a growing trend in seasonal UTCI anomalies, especially during summer and spring. In addition, there is a notable increase in the number of days above the defined UTCI thresholds for each season. Average annual UTCIs values also show a positive, rising trend, ranging from 0.50 °C to 1.33 °C. The most significant deviations from the average UTCI values, both seasonal and annual, were recorded in 2000, 2007, 2012, 2015, 2017, and 2018.
This paper presents a general framework for environmental risk assessment for the project "Jadar" -exploitation and processing of minerals "Jadarit". Conceptually, the paper is set up to provide insight into the applicability of a given model of environmental risk assessment. This model is based on a scientific and proven methodology. The paper emphasizes the complexity of assessment and the need for a broad scientific approach. This environmental risk assessment is based on three potential sources of risk: mining activities, production-industrial activities and the generation of industrial waste.As a possibility of negative impacts on the territory of the "Jadar" project, it is assumed that ecosystems, habitats and the environment would suffer consequences in general. The paper is expected to stimulate discussion and offer a proposal for solving this issue -the problem.
