Opis:: Global Navigation Satellite Systems (GNSS) are increasingly used as the main source of Positioning, Navigation and Timing (PNT) information for inland water navigation. In order to enable automated driving and facilitate driver assistant functions, it becomes of crucial importance to ensure high reliability and accuracy of the GNSS-based navigation solution, especially in challenging environments. One challenging phase of inland waterway navigation is bridge passing which leads to non-line-of-sight (NLOS) effects such as multipath and loss of tracking. This work presents a Precise Point Positioning (PPP) based algorithm in a two-antenna system where one antenna is at the bow and the other is at the stern. Additionally, gyroscope data from an IMU is used. In contrast to a separated position calculation of the two antennas, only one antenna position is estimated and the other is derived from the baseline between the antennas. This allows for accurate positioning even if one antenna does not receive any GNSS measurements. The presented scheme is evaluated using real measurement data from an inland water scenario with multiple bridges. In comparison with a standard PPP scheme as well as an RTK algorithm, the presented approach shows clear advantages in challenging scenarios.

Opis:: An accurate short-term global solar irradiation (GHI) forecast is essential for integrating the photovoltaic systems into the electricity grid by reducing some of the problems caused by the intermittency of solar energy, including rapid fluctuations in energy, management storage, and the high costs of electricity. In this paper, the authors proposed a new hybrid approach to forecast hourly GHI for the Al-Hoceima city, Morocco. For this purpose, a deep long short-term memory network is trained on a combination of the hourly GHI ground measurements from the meteorological station of Al-Hoceima and the satellite-derived GHI from the neighbouring pixels of the point of interest. Xgboost, Random Forest, and Recursive Feature Elimination with cross-validation were used to select the most relevant features, the lagged satellite-derived GHI around the point of interest, as input to the proposed model where the best forecasting model is selected using the Grid Search algorithm. The simulation and results showed that the proposed approach gives high performance and outperformed other benchmark approaches.

Opis:: A statistical analysis of Baltic Sea upwelling has been carried out to cover, for the first time, the entire sea area for the period 1990–2009. Weekly composite SST maps based on NOAA/AVHRR satellite data were used to evaluate the location and frequency of upwelling. The results obtained were analysed and compared with earlier studies with excellent agreement. Our study enables the most intense upwelling areas in the entire Baltic Sea to be evaluated. According to the analysis of 443 SST maps, the most common upwelling regions are found off the Swedish south and east coasts (frequency 10–25%), the Swedish coast of the Bothnian Bay (16%), the southern tip of Gotland (up to 15%), and the Finnish coast of the Gulf of Finland (up to 15%). Pronounced upwelling also occurs off the Estonian coast and the Baltic east coast (up to 15%), the Polish coast and the west coast of Rugen (10–15%); otherwise the upwelling frequency was between 5 and 10%. Additionally, simulated SST distributions derived from a Baltic Sea numerical model were analysed for the same period. Furthermore, at specific positions close to the coastline, surface winds based on the SMHI meteorological data base were analysed for the same 20-year period. Wind components parallel to the coast were discriminated into favourable and unfavourable winds forcing upwelling. The obtained frequencies of upwelling-favourable winds fit very well the observed upwelling frequencies derived from satellite SST maps. A positive trend of upwelling frequencies along the Swedish east coast and the Finnish coast of the Gulf of Finland was calculated for the period 1990–2009.

Opis:: The water regime is the main factor contributing to the formation of landscapes in the river deltas of arid zones, any fluctuations in which lead to a change in the integral hydromorphic landscape. After the construction of the Kapshagai reservoir, the anthropogenic load on the ecosystem of the Ili River delta increased, as a result of which degradation processes, such as drying out and salinization, intensified. In the short term, this phenomenon may lead to the desertification of about 1 million ha of land in the modern river delta. In this regard, the main goal of this study is to look at the processes of desertification in the modern delta of the Ili River, using remote sensing data, which allows for quick identification of the long-term dynamics of degradation processes. For this, the authors used satellite data from Landsat 1–5 MSSS and Landsat 8OLI satellites for 1979 and 2019 and soil analysis data obtained through the ground (field) surveys. Using regression analysis of space and soil data, predictors for interpreting space images were identified and maps of landscape drying and soil salinization were compiled, reflecting the changes that have occurred over the past 40 years. As a result, it was found that in 2019, compared to 1979, the area of landscapes covered with vegetation had decreased by 12% and there was a transformation of hydromorphic landscapes into salt marshes and solonetzes. Over the past 40 years, the volume of non-saline soils has decreased by 41.3% and the volume of saline soils has increased to varying degrees. That is, at present, on the territory of the modern delta, a difficult land improvement situation has developed associated with the cessation of spring and summer floods due to the intensive water use at the Chinese and Kazakh sides.

Opis:: Mediterranean regions have experienced significant soil degradation over the past decades. In this context, careful land observation using satellite data is crucial for understanding the long-term usage patterns of natural resources and facilitating their sustainable management to monitor and evaluate the potential degradation. Given the environmental and political interest on this problem, there is urgent need for a centralized repository and mechanism to share geospatial data, information and maps of land change. Geospatial data collecting is one of the most important task for many users because there are significant barriers in accessing and using data. This limit could be overcome by implementing a WebGIS through a combination of existing free and open source software for geographic information systems (FOSS4G). In this paper we preliminary discuss methods for collecting raster data in a geodatabase by processing open multi-temporal and multi-scale satellite data aimed at retrieving indicators for land degradation phenomenon (i.e. land cover/land use analysis, vegetation indices, trend analysis, etc.). Then we describe a methodology for designing a WebGIS framework in order to disseminate information through maps for territory monitoring. Basic WebGIS functions were extended with the help of POSTGIS database and OpenLayers libraries. Geoserver was customized to set up and enhance the website functions developing various advanced queries using PostgreSQL and innovative tools to carry out efficiently multi-layer overlay analysis. The end-product is a simple system that provides the opportunity not only to consult interactively but also download processed remote sensing data.

Opis:: The paper presents the campaigns of mobile satellite measurements, carried out in 2009-2015 on the railway and tram lines. The accuracy of the measurement method has been analysed on the basis of the results obtained in both horizontal and vertical planes. The track axis deviation from the defined geometric shape has been analysed in the areas clearly defined in terms of geometry, i.e. on the straight sections and sections with constant longitudinal inclination. The values of measurement errors have been estimated on the basis of signals subjected to appropriate processes of filtration. The paper attempts to evaluate the changing possibilities of using the GNSS techniques to determine the shape of the railway track axis from 2009 to 2015. The determined average value of the measurement error now equals a few millimetres. This achievement is very promising for the prospects of mobile satellite measurements in railway engineering.

Opis:: In this paper, authors present results of accuracy verification of the Trimble RTX technology. The GNSS receiver Spectra Precision SP60 was used in Cyprus (Kato Paphos Archaeological Park). To evaluate the accuracy of the receiver, two measuring test networks (consisting of 30 and 55 control points) were established. All points were determined in four measuring cycles. Additionally, in order to make more advanced analysis of the data, the bases were also measured by using another GNSS receiver - Geomax-Zenith 25. The point positions, in this case, were conducted in the local coordinate system of Kato Paphos Archaeological Park by using RTK positioning technology. To make a comparison, it was necessary to transform the coordinates based on different groups of fitting points. Analysis allowed to conclude that the Spectra Precision SP60 receiver and the RTX Trimble technology guarantee repeatable results (on the level of 4 cm) of point positioning measurements.
W artykule autorzy przedstawiają wyniki analizy dokładności technologii Trimble RTX. Odbiornik GNSS Spectra Precision SP60 wykorzystano podczas badań na Cyprze (Park Archeologiczny Kato Pafos). Aby ocenić dokładność odbiornika, ustalono dwie bazy testowe (składające się z 30 i 55 punktów kontrolnych). Wszystkie punkty zostały określone w czterech cyklach pomiarowych. Dodatkowo, w celu bardziej zaawansowanej analizy danych, pomiary zostały również wykonane przy użyciu innego odbiornika GNSS - Geomax-Zenith 25. Pozycjonowanie w tym przypadku, zostało przeprowadzone w lokalnym układzie współrzędnych parku archeologicznego Kato Pafos z wykorzystaniem technologii pozycjonowania RTK. W celu porównania wyników badań konieczne było przetransformowanie współrzędnych do jednego układu. Transformację wykonano na podstawie różnych grup punktów dostosowania. Analiza otrzymanych wyników pozwoliła stwierdzić, że odbiornik Spectra Precision SP60 i technologia RTX Trimble gwarantują porównywalne wyniki pozycjonowania (na poziomie 4 cm).

Opis:: The objective of the study was to compare the sum of actual sunshine duration in Poland, based on satellite and ground-based measurements during the period of 1983-2015. Results from the first group of data were derived from sunshine duration measurements from 44 surface synoptic stations belonging to the Polish Institute of Meteorology and Water Management (IMGW-PIB). The second group of data includes values from observations of Meteosat geostationary satellites (SARAH-2 climate data record), provided by the EUMETSAT Satellite Application Facility on Climate Monitoring (CM SAF). The study showed that in Poland, values of linear correlation coefficients (r) between both datasets are high, and range between 0.80 and 0.95. Differences in daily sums of sunshine duration are low, with the prevalence of positive deviations, i.e. slightly higher values for satellite data. The largest positive deviations were found in Tarnów, Zielona Góra, and Racibórz (+0.3 h), with equivalent negative deviations in Warsaw and on Kasprowy Wierch (−0.4 h). Moreover, minor discrepancies were found for the long-term variability of the mean annual sums of actual sunshine duration. However, after 1995, the deviations were insignificant, and averaged 4 hours. Differences between both data series are caused by several factors, including an underestimation of aerosols optical depth (AOD), as well as the failure to consider the type of clouds covering the Sun’s disc. With its high spatial resolution (0.05° × 0.05°), the satellite data can be a valuable source of information, particularly in regional studies of the spatial variation of sunshine duration.

Opis:: Autorzy artykułu, poszukując alternatywnych dla zdjęć lotniczych źródeł danych obrazowych, określili stopień przydatności panchromatycznych zobrazowań QuickBird w procesie generowania true ortho. W badaniach metodycznych wykorzystano sceny pozyskane przy różnych kątach wychylenia sensora satelity od nadiru, obejmujące swym zasięgiem centrum Warszawy. Elementy orientacji zewnętrznej poszczególnych scen wyznaczono z dokładnością na poziomie ½ piksela obrazu źródłowego. Do procesu ortorektyfikacji panchromatycznych obrazów QuickBird włączono zbiór punktów zapisanych w regularnej siatce o oczku 20 m, których dokładność położenia wysokościowego wynosiła 0.6 m. Podstawowy materiał badawczy stanowiły ortoobrazy wygenerowane z pikselem 1m, przy kątach wychylenia sensora satelity od nadiru wynoszących 5°, 11° oraz 18°. Stwierdzono, że dokładność ortoobrazów wygenerowanych na podstawie tak skonfigurowanych danych wejściowych nie zależy zasadniczo od kąta wychylenia sensora satelity i wynosi m P = 0.56 m. Główny etap badań dotyczył określenia wpływu wychylenia sensora obrazującego satelity na dokładność odwzorowania na ortofotomapie przestrzennych obiektów terenowych. Na podstawie porównania na ortoobrazach oraz mapie numerycznej w skali 1:10 000 wartości współrzędnych płaskich, odwzorowanych obiektów terenowych o wysokości nie przekraczającej 30 m, stwierdzono, że względny błąd średni położenia tych obiektów nie przekracza m P = 2.4 m, w przypadku, gdy sensor obrazujący systemu QuickBird jest wychylony od nadiru nie więcej niż 5°. Wykazano, że wartość tego błędu wzrasta do m P = 5.8 m przy wzroście kąta wychylenia sensora do 11° oraz do m P = 9.7 m przy kącie wychylenia sensora wynoszącym 18°. Stwierdzono, że ortofotomapy w skali 1:10 000, wygenerowane z panchromatycznych scen QuickBird, pozyskanych przy wychyleniu sensora nie większym od 5°, stanowią dla większości obiektów terenowych produkt true ortho.
Alternative satellite data were studied for use in the generation of a true ortho of urban areas. The methodology of the generation of true ortho was elaborated using QuickBird Pan data of the Warsaw area. QuickBird data with different angle of acquisition was tested. The orientation of the scenes was done using RPC data and an additional 9 GCPs and Toutin’s model. The accuracy of the orientation of each scene was checked on 64 independent check points (ICPs). The accuracy on GCPs was less than 0.5 pixel of orientation of the QuickBird Pan data. RMSE on ICPs was less then 0.45 m. Orthorectification of the scenes was performed with the use of a DEM with a 20×20 m grid and RMSE (Z) < 0.6 m. RMSE (XY) = 0.56 m was achieved on the generated orthophotomaps with an output pixel size of 1×1 m for different collection angles of the image data. The main investigation was done for assessment of the planimetric accuracy of high buildings on the generated orthophotomaps. Digital topographic maps on a scale of 1:10 000 were used for planimetric accuracy assessment. RMSE (XY) < 2.4m for the acquisition angle less then 5° from nadir was achieved. The acquisition angle was 11° from nadir RMSE (XY) = 5.8 m and for 18° RMSE (XY) = 9.7 m . These results have been achieved only for spatial structures less than 30 m high. Panchromatic QuickBird data acquired close to the nadir angle could be used for elaborating the “true ortho” of an urban area.

Opis:: The aim of the study was to diagnose the main trends of changes in land cover in selected communes of Polish metropolitan areas. Detailed studies were conducted in deliberately selected housing estates located in the core of metropolitan area (at least one housing estate) and communes located directly at the border of cities and located on the outskirts of metropolitan areas. The examined communes also differed in the quality of natural conditions of agricultural production. The study used LANDSAT 5 TM and RapidEye satellite images from three limited-time registrations (1996/1999, 2011, 2016/2017). On the basis of remote sensing data, changes in land use were specified by presenting them in a graphic form as compilation of numerical maps. The analyses were performed on processed images (colour compositions), which were subjected to supervised classification using the maximum-likelihood technique. The quality control of supervised classification showed accuracy of 89.3% for LANDSAT 5 TM scene analyses and 91.8% for RapidEye images. Kappa coefficient for the discussed classification was: 0.84 (LANDSAT TM) and 0.89 (Rapid Eye). The results obtained for individual metropolitan areas allow to identify the directions of changes (Land Use Change Cover) taking place in them, with consideration to specificity of each of them.

Opis:: The operational limitations are discussed at the IMO as a part of the second generation intact stability criteria. Since it is a first attempt to introduce operational efforts into safety regulations, comprehensive discussions are necessary to realize practically acceptable ones. Therefore this study investigates actual navigation routes of container ships and pure car carriers in the trans-North Pacific Ocean in winter, because they are prone to suffer significant parametric roll which is one of stability failure modes. Firstly, interviews are made to shipmasters who have experiences to have operated the subject ships to identify major elements for route selection in the North Pacific Ocean. Secondly, sufficient number of actual navigation records is collected from Satellite AIS data to derive the weather criteria for the route selection in severe weather condition. Finally, shipmaster’s on-board decision-making criteria are discussed by analysing the ship tracking data and weather data.

Opis:: The probabilistic Ant Colony Optimization (ACO) approach is presented to solve the problem of designing an optimal trajectory for a mobile data acquisition platform. An ACO algorithm optimizes an objective function defined in terms of the value of the acquired data samples subject to different sets of constraints depending on the current data acquisition strategy. The analysis presented in this paper focuses on an environment monitoring system, which acquires in-situ data for precise calibration of a water quality monitoring system. The value of the sample is determined based on the concentration of the water pollutant, which in turn is obtained through processing of multi-spectral satellite imagery. Since our problem is defined in a continuous space of coordinates, and in some strategies each point is able to connect to any other point in the space, we adopted a hybrid model that involves a connection graph and also a spatial grid.
