    Opis:
    The conducted review presents the possibility of using artificial neural networks in sectors related to environmental protection, agriculture, forestry, land uses, groundwater and bathymetric. Today there is a lot of research in these areas with different research methodologies. The result is the improvement of decision-making processes, design, and prediction of certain events that, with appropriate intervention, can prevent severe consequences for society. The review shows the capabilities to optimize and automate the processes of modeling urban and land dynamics. It examines the forecasts of assessment of the damage caused by natural phenomena. Detection of environmental changes via the analysis of certain time intervals and classification of objects on the basis of different images is presented. The practical aspects of this work include the ability to choose the correct artificial neural network model depending on the complexity of the problem. This factor is a novel element since previously reviewed articles did not encounter a study of the correlation between the chosen model or algorithm, depending on the use case or area of the problem. This article seeks to outline the reason for the interest in artificial intelligence. Its purpose is to find answers to the following questions: How can artificial neural networks be used for spatial analysis? What does the implementation of detailed algorithms depend on? It is proved that an artificial intelligence approach can be an effective and powerful tool in various domains where spatial aspects are important.

    Opis:
    Ignacy Domeyko was born on July 31, 1802 in Niedźwiadka, Novogrodek district. After attending the Piarist College in Szczuczyn he studied at the Vilna University and got the M. Sc. degree in 1822. As member of the illegal Philomat Society was interned till 1829. In 1831 as participant of anti-Russian insurrection had to escape to Prussia, from where moved to Saxony and France. In the years 1832-1838 Domeyko was studying exact and geosciences at Sorbonne and École des Mines. Invited by the Government of Chile was teaching physico-chemical and geo-sciences in the Coquimbo College in La Serena in the years 1838-1846, carrying out large-scale geological and ethnographic field studies as well as chemical-mineralogical investigations. In the years 1846-1884 Domeyko was very active as academic teacher and in the period 1867-1883 as rector of the Chile University in Santiago, continuing research works and reforming local education system. His many-sided activity contributed significantly to economic and educational progress of Chile. In the final stage of his life (1884-1888) Domeyko, as already world-wide known scientist, could visit his homeland and other European countries, as well as Holy Land, but on the way back felt ill and on January 23, 1889 died in Santiago admired and venerated by Chileans as their apostle of science and education. The present paper deals with essential Domeyko's achievements in geosciences. Already during his stay in Paris the results of his observations on sinking of the area of East Prussia in historic times were published and Domeyko has prepared the geographic atlas of the territory of the native Polish-Lithuanian Commonwealth but only its part could be printed. In Chile, apart from didactic activity, accented by edition of handbooks on mineralogy and assaying, Domeyko was carrying out large-scale geological, mining and mineralogical investigations of Andes showing predilection to chemical analyses of collected materials. As follows from the inspection of archival materials, he is the author of at least 160 analyses of various, often chemically very complicated, minerals (including meteorites) and about 60 analyses of waters. This resulted in the discovery of several new minerals which were announced in renowned European periodicals. One of them - copper arsenide - was named by W. Haidinger domeykite. Besides, several Andean fossils sent by Domeyko to France were by A. d'Orbigny and other French palaeontolo- gists named after their discoverer. Following several minor papers on regional geology, including detailed studies of volcanic phenomena, he published in 1878 in Polish a monograph on Chilean Cordilleras and ore deposits, comparing some their fragments with similar horizons in the Polish Carpathians. These and other problems treated by Domeyko in numerous publications are discussed in the present paper. Domeyko's achievements were highly appreciated by several European and American scientific societies and universities by conferring him memberships and honorary doctorates. Moreover, due to his exceptional personality and spirituality, expressed in deeply Christian virtues realized in private and social life, Domeyko is a candidate for beatification. Geoscientists of Poland, Lithuania, Chile, Belorussia, France and other countries are celebrating 200th anniversary of his birth, paying homage to this eminent citizen of the world.

    Opis:
    The demandfor important raw materials for the Chinese economy achieved the scale about the half of the world's demand. Investment decisions taken in this matter enable a complete identification of mineral deposits, which is significant for both domestic and foreign investments. Geological studies and prospecting for useful ore mineral deposits have been conducted by special research institutions that prepare information about their reserves and output profitability. The University of Geological Studies in Beijing, with about 40,000 students, plays a key role in this activity. For example, a development of both reforms in extracting bituminous coal and gold deposits was discussed.

    Opis:
    As early as at the beginning of the 20th century, outstanding Polish geologists associated with the Academy of Arts and Sciences, operating in the Austrian Partition, developed concepts for the development of geology in independent Poland. As soon as independence became a fact, the Polish Geological Institute was established, and a little later - the Polish Geological Society. The specific goals of these institutions were different, but the overriding goal - the development of Polish geology and the geological community - was common. PGI and PGS interacted very closely with each other. PGI employees for many years played an important role in the Society's structure, including the function of the President. They initiated the establishment of regional branches, and were always scientifically active, presenting a significant percentage of scientific lectures prepared a spart of PGS activities. They were the organizers or co-organizers o fa significant part of the PGS Congresses, and in most cases of the post-war history, PGI was the publisher of the Congress Guides. The symbiosis of these two important institutions served both themselves and Polish geology as a whole.

    Opis:
    The paper is part of a debate on the correctness and validity of the concept of creating the Polish Geological Agency.With a purpose to draw attention to thes upranational perspective, it indicates the international and EU requirements set for the Polish geological survey. Next, it presents the functioning of the German geological survey as the respective body that in the Opinion of the Legislative Council of 26 January 2018 on the draft act on the Polish Geological Agency can be considered as an example of a modern and well-functioning geological survey. The research problem, which is the issue of the necessity to conduct institutional amendments in the subject area, is based on the following assumptions: 1) the role of geological surveys changes in response to current challenges faced by the national, organizational and global community; 2) legal and organizational tasks and forms of state geological surveys undergoing changes, which is a consequence of changes in the role of these surveys in the national, organizational and world communities.
