Wraz z postępem technicznym i technologicznym sprostanie wymaganiom dzisiejszych czasów skłoniły człowieka do wynajdowania nowych sposobów i metod pozyskiwania danych przestrzennych z wymaganą dokładnością. Do takich danych należy zaliczyć dane satelitarne. Stanowią one niezwykle cenne źródło informacji, wykorzystywane do wykonywania badań i analiz z zakresu obserwacji powierzchni Ziemi, zjawisk geofizycznych jak i meteorologicznych. Tematyka niniejszego artykułu skupia się na wykorzystaniu danych teledetekcyjnych, jako źródeł umożliwiających ocenę zmian sposobu użytkowania gruntów. W tym celu przedstawiono główne programy umożliwiające pozyskiwanie danych przestrzennych, tj. program Landsat i Copernicus. Nie sposób zapomnieć również o systemie ISOK (Informatycznym Systemie Ochrony Kraju). Jego znaczenie w sektorze społecznym i ekonomicznym pomaga wykrywać wczesne stadia zagrożeń i katastrof naturalnych. W odniesieniu do okresowości wykonywanych pomiarów w ramach wymienionych programów i systemów, jest to nieodłączny element przeprowadzanych badań obranych obszarów. Bowiem obserwacje zmian w czasie dają doskonałe rezultaty, ponieważ dynamika stref przyrodniczych jak i urbanistycznych jest niebagatelna.

Along with technical and detailed progress, meeting the requirements of time prompted man to invent new ways and methods of spatial acquisition with the required participation. Whether such data must come from regional data. They are extremely valuable sources of information that are used to perform research and analyze the range of observations of the Earth's surface, geophysical and meteorological phenomena. The subject matter of the article focuses on the acquisition of remote sensing data as sources enabling the assessment of changes in land use after land consolidation works. For this purpose, the main programs for acquiring spatial data, i.e. Landsat and Copernicus, were used. It is also impossible to forget about the ISOK system (IT System for Country Protection). Its recognition in legal and economic proceedings helps to detect early stages and natural circumstances. In order to examine the period of taking measurements under specific tools and systems, it is an integral part of the research of the selected areas. Because I know that observations of changes over time give excellent results, because the dynamics of natural and urban zones is considerable.

Niniejszy artykuł skupia się na skontrastowaniu dwóch źródeł danych umożliwiających ocenę zmian sposobu użytkowania gruntów. W artykule przedstawiono ideę Informatycznego Systemu Ochrony Kraju (ISOK). W nawiązaniu do wspomnianego projektu, omówiono rodzaj danych jaki jest wykorzystywany do jego realizacji. Mowa tutaj o danych LiDAR, czyli danych w postaci chmur punktów, charakteryzujących się wysoką dokładnością i komfortem pozyskiwania. Kolejnym zasobem, będącym elementem rozważań są satelitarne zdjęcia CIR, które w przeciwieństwie do standardowych kompozycji barwnych RGB niosą znacznie więcej informacji, ponieważ oprócz reprezentacji sytuacyjnej danego obszaru, uwypuklają procesy i zjawiska, których nie można dostrzec na podkładach. Na podstawie tych dwóch odmiennych źródeł danych wykonano analizy pozwalające określać zmiany w sposobie użytkowania gruntów.

High-resolution aeromagnetic and Landsat-8 data were utilized for the structural investigation of the Igarra Schist Belt located where the Precambrian crystalline basement is unconformably overlain by the late-Cretaceous Anambra Basin fill. Analysis of the Landsat-8 data exhibits major lineaments that trend in E–W, ENE–WSW, NNW–SSE and N–S directions. Results from the analysis of total field anomaly data using total gradient amplitude and tilt angle of the horizontal gradient also show these same lineament trends. The superimposition of Landsat-8 and aeromagnetic data-derived lineaments resulted in the mapping of the regional lineaments, which provide clues to structurally controlled gold mineralization in the Igarra Schist Belt region. Details mapped from the remote sensing data show surface contacts that correspond to the boundary between the Igarra Schist Belt and Anambra Basin mapped from aeromagnetic data. The source parameter imaging of the aeromagnetic data provides depth estimates of the magnetic basement of the Igarra Schist Belt and Anambra Basin, which varies from 50 to above 650 m. The integration of the remote sensing and aeromagnetic lineaments with the 3-D Euler deconvolution results reveals that the locations of cluster solutions alignment with lineaments are target areas for gold mineralization, which is correlative to gold occurrences in the region.

The shoreline is an important geographical zone, and knowledge of its accurate location can be crucial for coastal management and mapping. The ever-increasing number of aerial and satellite sensors is leading to research related to the development of new methods for the automatic extraction of the shoreline. Currently, there is a lot of research in this area with different research methodologies. In this paper, an analysis of shoreline extraction methods was carried out. Based on the analysis undertaken, current research processes in this field can be verified. This enabled the further evaluation of the research methodologies studied, including the identification of basic assessment elements for shoreline extraction accuracy. Practical aspects of this work include the ability to establish the correct methods to assess the accuracy of extracted shorelines for both research and production processes related to data extracted from remotely sensed images.

Based on the results of regular monitoring and remote sensing data the patterns of water temperature and ice regime of the Dnipro River within Kyiv, as affected by global warming and a hydropower plant, were identified. The characteristic features of this stretch of the river are increasing water temperature, and the decreasing thickness and duration of ice cover. The largest water temperature increase is in summer, with a somewhat smaller increase in autumn. The increase of water temperature in spring is much less than the increase in air temperature. In summer, the gradient of water temperature increase is a little bit less than that of air temperature. In autumn, the gradient of water temperature increase is larger than the gradient of air temperature increase. From April to August the lowest water temperature is usually observed near the Kyivska hydropower plant (HPP), which is located upstream. During this period the water temperature downstream from HPP increases. The uneven daily operation of HPP causes the alternation of areas with different temperature along the Dnipro River. In the cold season the water temperature in the Dnipro River is usually higher than in other nearby urban water bodies. Freezing of the water area usually starts from the small and shallow lakes and ponds. The main branch of the Dnipro River freezes last. On the whole, the sequence of ice melting on the waterbodies is the reverse of the freezing process. The longest ice cover duration in spring is observed in the bays with small water exchange, mainly located at a large distance from Kyivska HPP.

A three-dimensional numerical model was applied to simulate the Black Sea Water (BSW) outflux and spreading over the North Aegean Sea, and its impact on circulation and stratification–mixing dynamics. Model results were validated against satellite-derived sea surface temperature and in-situ temperature and salinity profiles. Further, the model results were post-processed in terms of the potential energy anomaly, ϕ, analyzing the factors contributing to its change. It occurs that BSW contributes significantly on the Thracian Sea water column stratification, but its signal reduces in the rest of the North Aegean Sea. The BSW buoyancy flux contributed to the change of ϕ in the Thracian Sea by 1.23 × 10-3 W m-3 in the winter and 7.9 × 10-4 W m-3 in the summer, significantly higher than the corresponding solar heat flux contribution (1.41 × 10-5 W m-3 and 7.4 × 10-5 W m-3, respectively). Quantification of the ϕ-advective term crossing the north-western BSW branch (to the north of Lemnos Island), depicted a strong non-linear relation to the relative vorticity of Samothraki Anticyclone. Similar analysis for the south-western branch illustrated a relationship between the ϕ-advective term sign and the relative vorticity in the Sporades system. The ϕ-mixing term increases its significance under strong winds (> 15 m s-1), tending to destroy surface meso-scale eddies.

Based on the survey records on netz-phytoplankton (>76 μm) collected in the South China Sea (SCS) during the cruise from the 21st August to the 18th October, 2012, the species composition, biodiversity and its spatial distribution were studied. The identified 326 phytoplankton species belonged to 75 genera and 4 phyla. Thalassionema nitzschioides was the most dominant species accounting for 33.24% of the total cell abundance, followed by Bacteriastrum furcatum − 8.69%. Whereas the phytoplankton cell abundance (cells l-1) was the highest in the Zhubi Reef (1106.45 ± 2475.38), the southern SCS (396.84 ± 969.87), the western SCS (90.82 ± 144.66) and the northern SCS (66.48 ± 70.89) in order. The distribution of phytoplankton appears to be affected by the Mekong river discharge and particles derived in Sumatra and Kalimantan from biomass burning, nutrient concentrations, the South China Sea Warm Current (SCSWC). The evaluation of biodiversity indices indicated the high level of species richness, evenness and biodiversity in the survey area.

Mimo niepodważalnej atrakcyjności wysokorozdzielczych obrazów satelitarnych, wzrastają oczekiwania co do podwyższenia ich użyteczności w wielkoskalowych zastosowaniach tematycznych. W celu podniesienia użyteczności obrazów, amerykańskie konsorcjum DigitalGlobe umieściło na orbicie najnowszego satelitę z serii WorldView. Względem swoich poprzedników, QuickBirda i WorldView-1, a także konkurencyjnych Ikonosa i GeoEye-1, wyróżnia się on zwiększeniem rozdzielczości spektralnej i precyzji lokalizacji obrazów. Nowe kanały spektralne mają służyć nowym oczekiwaniom dzięki lepszym zdolnościom interpretacyjnym. Niniejsza praca jest próbą oceny potencjalnych możliwości interpretacyjnych obrazów WorldView-2. Przykładowe fragmenty ocenianego obrazu obejmują część miasta Poznania, którą zarejestrowano 10.05.2010 r. Możliwość pozyskania tak interesującego obrazu otwiera też pole do poszukiwania rozwiązań, w jak najlepszym stopniu spełniających zapotrzebowania praktyczne.

Despite the indisputable attractiveness of VHRS images, expectations of their usefulness in large-scale thematic applications increase. In order to improve the usefulness of very high resolution images, American consortium DigitalGlobe has put new satellite in orbit - the latest of a series of WorldView Relative to its predecessors - QuickBird and WorldView-1, as well as competitive IKONOS and GeoEye-1, it is distinguished by an increase in spectral resolution and precision of the location of the images. New spectral bands should serve the new demands with better interpretative skills. This paper is an attempt to assess interpretational potential of WorldView-2 images. Examples include parts of the rated image of the city of Poznan, registered on May 10 this year. The possibility of obtaining such an interesting image opens a field to search for solutions, which in the best possible extent meet the practical demand.
