The Geographical Information Systems technology is used in many fields where the spatial information is very important and relevant, that means in all fields that use a system for saving, analyzing and representing the data which are processed. The aim of this paper is using modern technology for monitoring the environment. Geographical Information System together with remote sensing have a very important role in decision process regarding the environment. Integration of remote sensing images in a Geographical Information System which enables complex spatial analysis is a useful and modern solution for environmental management and decision-making process. Satellite images contain various information that can support environmental monitoring, images that can be analyzed and interpreted in various ways by using the Geographical Information System tools.
Czyste środowisko jest niezbędne dla zdrowia ludzi i jakości życia. Rozwijające się sektory, które pomagają zaspokoić potrzeby i kom-fort, mają negatywny wpływ na jakość środowiska, w którym żyjemy. Wykorzystywanie zasobów naturalnych bez troski o potrzeby ludzi prowadzi do niszczenia środowiska. Zmiany klimatu, erozja, zwiększenie ilości dwutlenku węgla w powietrzu, którym oddychamy, są wynikiem zaspokojenia innych potrzeb, takich jak jedzenie, ciepło, transport, komfort w naszym domu.
A thematic map contains a spatial database that allows the user to add new information to that database. The ability to combine a variety of datasets in a variety of ways makes any GIS a useful tool for almost any field of knowledge. From routinely performing work-related tasks to scientifically exploring the complexity of our world, GIS offers people the geographic advantage of becoming more productive, more aware, and more receptive to the planet Earth. A GIS can be defined as a system designed to capture, store, manipulate, analyze, and visualize geographically referenced data. Thematic maps are the result of spatial analysis sets made in GIS programs. Spatial analysis includes the techniques by which the relationships between entities are studied, from a topological, geometric or geographical point of view. Depending on the requirements and the existing data in the database, the maps may have different thematic results: demographic, social, economic, analysis, prediction, evaluation, anticipation maps, etc., depending on what you want to do analyze.
Coal is a macromolecular compound. At high temperatures, by coal pyrogenesis, coke and volatile products will result.The volatile products from coal form the coke gas and coke tar from which a very large number of aromatic compounds can be extracted.The aromatic compounds extracted from domestic and foreign coal tar were compared in this paper, together with their effects overthe human and animal health.
Raport oceniający grunt może obejmować ocenę nieulepszonych gruntów (gruntów zagospodarowanych pod cele rolnicze lub rozwojowe), gruntów stanowiących teren (gruntów utworzonych i gotowych do wykorzystania w określonym celu) lub części gruntuzabudowanego własność. W każdym z tych przypadków Valuer musi opisać i przeanalizować dany grunt. Opis gruntu lub terenu toszczegółowa lista, która obejmuje: opis prawny, inne tytuły i informacje o fizycznych cechach gruntu. W analizie terenu lub terenuinformacje te są dokładnie badane w odniesieniu do cech sąsiedztwa, które wpływają na użyteczność i trwałość gruntu lub terenu, sąprzydatne w określaniu najlepszego wykorzystania (uznanego za bezpłatne) i szacowaniu wartości terenu.
The aim of the study was to evaluate the phenomenon of land tilting and the tilting distance as a secondary effect of surface coal mining in the Jiu Valley area, Romania. To evaluate the tilting phenomenon, through the two considered elements (inclination – Lt, tilting distance – Td) 16 control points (CP1 to CP16) were used whose coordinates were measured in the Stereographic 1970 projection system, the 1975 Black Sea elevation system at an initial moment (t0) and at the current moment (t1). The static method was used by GPS technology to measure the elevations of the control points. Through descriptive statistical analysis, a general characterization of the set of recorded values was obtained, and the ANOVA test confirmed the safety of the data and the presence of variance in the data set. From the analysis of the recorded values, a Spline type model was obtained that described the variation of Lt in relation to Td, under conditions of statistical safety ( ɛ¯ = 0.137302). Regression analysis facilitated the obtaining of equation-type models, which described the variation of Lt and Td in relation to the X, Y and Z coordinates of the control points (t0, t1), under conditions of statistical certainty (R2 = 0.697, p=0.014 for Td variation according to Z0 and Z1; R2 = 0.722, p=0.0094 for Td in relation to X0 and Z0). According to PCA, PC1 explained 61.303% of variance, and PC2 explained 38.697% of variance. The cluster analysis facilitated the obtaining of a dendrogram based on Euclidean distances, regarding the grouping based on the similarity of the control points in relation to the studied phenomenon, under conditions of statistical safety (Coph. corr.=0.957).
For the correct substantiation of many managerial decisions, the costs provided by the calculations are not sufficient. Because of itscomplexity, managerial decision may require consideration of costs other than accounting. Under these circumstances, the management of the mining enterprise is subject to the requirement of an economic (net different from the accounting, based on the result ofcalculations) approach of the decisional situation, which implies the ability to identify and quantify the costs of opportunity, implicitcosts, relevant costs, influenced, the costs "sunk".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
