Opis:
Due to growing demand for ground-truth in deep learning-based remote sensing satellite image fusion, numerous approaches have been presented. Of these approaches, Wald’s protocol is the most commonly used. In this paper, a new workflow is proposed consisting of two main parts. The first part targets obtaining the ground-truth images using the results of a pre-designed and well-tested hybrid traditional fusion method. This method combines the Gram–Schmidt and curvelet transform techniques to generate accurate and reliable fusion results. The second part focuses on the training of a proposed deep learning model using rich and informative data provided by the first stage to improve the fusion performance. The demonstrated deep learning model relies on a series of residual dense blocks to enhance network depth and facilitate the effective feature learning process. These blocks are designed to capture both low-level and high-level information, enabling the model to extract intricate details and meaningful features from the input data. The performance evaluation of the proposed model is carried out using seven metrics such as peak-signal-to-noise-ratio and quality without reference. The experimental results demonstrate that the proposed approach outperforms state-of-the-art methods in terms of image quality. It also exhibits the robustness and powerful nature of the proposed approach which has the potential to be applied to many remote sensing applications in agriculture, environmental monitoring, and change detection.

Opis:
Development of the geodetic and remote sensing techniques in the last decade makes it possible to carry out detailed geomorphological studies and acquire a high quality geospatially accurate data. One of the latest technologies available for collecting topography data is Light Detection and Ranging (LiDAR) which uses fast-firing laser to measure distances from small aircraft to the surface of the earth (Bowen et al. 2002). The study area occupies the Middle Latvia lowland. Previous studies of the River Ogre valley has been made in 1970s (Eberkhard 1972). Recent studies have been carried to supplement information of the distribution of river terraces. Riverbed of the River Ogre valley in Middle Latvia lowland is mostly straight or meandering, with individual branched stages. Valley width mostly ranging from 250 m to 500 m, while in some stages width is only 100 m, while in others reaches up to 1400 m. For this study, classified LiDAR data in ASCII format have been acquired from Latvian Geospatial Information Agency. Digital elevation model (DEM) with raster cell size 1×1 m has been made using Global Mapper v15software. DEMs with raster cell size 0.5×0.5 m and 2×2 m have been also made, however DEM with raster cell size 1×1 m was assessed as optimal, because the amount of data and information processing time, as well as terrain data quality is sufficient to achieve the objective. Such a choice of raster cell size is also based on other studies (Wheaton et al. 2010, Brasington et al. 2012). Longitudinal profile of the River Ogre has been made using DEM and is based on more than 400 valley cross profiles. The longitudinal profile consists of all of detected fragments of terraces, floodplain and elevation of valley margins.To ensure that the DEM is accurate, field observations were carried out and several terraces and shorelines of Quaternary palaeolakes were detected. For example, Zemgale palaeolake shoreline associated with River Ogre valley Ranka spectrum IV terrace, which is visible in the nature and clearly traced on elevation model. The obtained results show that six different terrace levels of Ranka spectrum were detected. I, II, and III terraces are related to levels of the River Daugava terraces, IV terrace is related to Zemgale paleolake but V and VI terrace is linked to various water levels of Daudzeva paleolake.

Opis:
Air pollution (especially near industrial enterprises that are located mainly in densely populated regions) is one of the most significant problems of modern ecology. The purpose of this research is to study nitrogen dioxide air pollution over Ukraine, which has a negative impact on human health. As part of the research over the territory of Ukraine, the real planar distribution of nitrogen dioxide (NO2) as well as its local emissions (which make the main contribution to this distribution) were revealed using the materials of the remote sensing of the Earth from the AURA satellite. The results were calculated for the multi-year period of 2005 through 2021 and separately for 2022, which characterized the full-scale war in Ukraine and which made it possible to identify priority polluters; namely, industrial enterprises (thermal power plants, heavy metallurgy enterprises, etc.). For 17 years, the average value of NO2 was 160.78 · 102 molecules/mm2; in 2022, its concentration decreased to 126.93·109 molecules/mm2. The war manifested itself due to the shutdown of industrial enterprises, which were (and remain) priority polluters in Ukraine (particularly in large cities).

Opis:
The interaction of Deep Learning (DL) methods with Geographical Information System (GIS) provides the opportunity to obtain new insights into environmental processes through the spatial, temporal and spectral resolutions as well as data integration. The two technologies may be connected to form a dynamic system that is incredibly well adapted to the evaluation of environmental conditions through the interrelationships of texture, size, pattern, and process. This perspective has acquired popularity in multiple disciplines. GIS is significantly dependant on processors, particularly for 3D calculations, map rendering, and route calculation whereas DL can process huge amounts of data. DL has received a lot of attention recently as a technology with a plethora of promising results. Furthermore, the growing use of DL methods in a variety of disciplines, including GIS, is evident. This study tries to provide a brief overview of the use of DL methods in GIS. This paper introduces the essential DL concepts relevant to GIS, the majority of which have been published in recent years. This research explores remote sensing applications and technologies in areas such as mapping, hydrological modelling, disaster management, and transportation route planning. Finally, conclusions on contemporary framework methodologies and suggestions for further studies are provided.

Aeromagnetic data was processed in order to delineate structural trends which may be indicative of potential gold mineral traps in the Watari hill gold prospect located between longitude 5°8''and 5°16'', and latitude 11°24'' and 11°30'' in Garin Hawal district, northwest Nigeria. Landsat-8 OLI data was processed to produce colour composite, band ratio and minimum noise fraction images that mapped the hydrothermal alteration zone in the study area. The multispectral images which were displayed in Red-Green-Blue colours were subsequently pan-sharpened to display a greater image resolution of the area. The application of enhancement algorithms such as an analytic signal to the aeromagnetic data over the alteration zone helped in mapping the mafic metavolcanics, felsic metasediments and intruding granitoid complexes. Further reductions using the second vertical derivative and tilt angle derivative filters aided in delineating fracture/faults and the contact zones of the formations, especially the metasediments-metavolcanic boundary that delineates the shear zone. This study showed that the low-angle geologic structure between the metasediments and metavolcanics where hydrothermal alteration is present is likely to accommodate veins of gold mineralization in the study area.

Opis:
This article presents the problem of climate warming and the effect of melting ice caps. The problem of climate warming is discussed in two stages. In the first stage, the factors affecting global warming are discussed in detail and the effects and risks of ablation extensively described. Analyses were conducted on data available online from NASA and Carbon Dioxide Information Analysis Center. The Greenland area (Jakobshavn Glacier) was selected to visualize glacier calving front changes. The analysis of changes was performed on the selected satellite images covering the summer period (June to September) provided by the Landsat program. Then, the changes in the position of the calving front of the Jakobshavn Glacier were visualized for the period 1985–2020, with a repeatability of every 5 years. Thus, our results addressed the challenges of environmental changes to remote sensing data processing. In addition to the visualization, a surface summary of these changes was presented in the study. The results were discussed in the context of climate change data processed by means of the GIS method. Furthermore, an analysis of the effects of greenhouse gases on glacier surface changes was performed. In summary, the results reveal that satellite imagery is an excellent source of data on which to visualize glacier calving rates, comparing individual layers showing the position of the glacier calving front and calculating the area of calved ice.

Opis:
Polityka Unii Europejskiej musi się opierać na spójnych i aktualnych informacjach przestrzennych niezbędnych zarówno do nakreślenia polityki Wspólnoty Europejskiej, jak i realizacji postanowień wynikających z dyrektyw Wspólnoty. Dwa programy Unii Europejskiej wychodzą naprzeciw tym oczekiwaniom, a mianowicie program INSPIRE oraz program GMES. W artykule omówiono te programy ze szczególnym uwzględnieniem roli fotogrametrii i teledetekcji. Prace nad projektem programu INSPIRE dotyczącym Europejskiej Infrastruktury Danych Przestrzennych rozpoczęto pod koniec lat 90. W wyniku działania Grupy Ekspertów programu INSPIRE i prac kilku Grup Roboczych opracowano wstępne założenia programu INSPIRE. Wynikiem tych prac było opracowanie projektu dyrektywy INSPIRE, który 23 lipca 2004 roku został przekazany do Parlamentu i Rady Unii Europejskiej celem przeprowadzenia procesu legislacyjnego. W wyniku prac prowadzonych w obu tych ciałach powstał dokument prezentujący wspólne stanowisko Rady, który miał być poddany głosowaniu w czerwcu 2006 roku na posiedzeniu plenarnym Parlamentu Europejskiego. Zgodnie z tym dokumentem podstawowe źródło informacji o terenie stanowić mają ortofotomapy satelitarne bądź lotnicze. Program GMES (Global Monitoring of Environment and Security) realizowany przez Komisję Europejską i Europejską Agencję Kosmiczną dotyczy permanentnego monitorowania naszego kontynentu, a głównie użytkowania Ziemi i dużych aglomeracji miejskich. Główne źródło informacji w tym programie stanowić będą średnio- i wysokorozdzielcze zdjęcia satelitarne.
The policy of the European Union must be based on condense and up-to date spatial information, necessary both to create the policy of the European Union as well as to implement and monitor the resolutions resulting from the directives of the Union. Two programmes of the European Union meet these expectations. These are INSPIRE and GMES programme. This article presents these programmes, focussing of the role of photogrammetry and remote sensing. The work on the project of the INSPIRE programme, referring to the European Infrastructure of Spatial Data started at the end of 1990s. As the result of the activities of the Group of Experts of programme INSPIRE and several Working Groups, preliminary premises for the INSPIRE programme were made. The result of this work was making the project of the Directive INSPIRE, which, on 23rd July 2004 was submitted to the Parliament and Council of the European Union for the legislation process. As the result of the work done in both these bodies, a document was issued. The title of the document was: Common Statement of the Council. The term of voting is June 2006, at the plenary session of the European Parliament. According to this document, the basic source of terrain information should be satellite or airborne orthophotomaps. Programme GMES (Global Monitoring of Environment and Security) realized by the European Commission and European Space Agency refers to permanent monitoring of our continent and mainly the use of Earth and large city agglomerations. Main source of information in this programme will be medium and high resolution satellite images.

Opis:
The understanding of the spatial and temporal dynamics of farmland processes is essential to ensure the proper crop monitoring and early decision making needed to support efficient resource management in agriculture. By creating appropriate crop management strategies, one can increase harvest efficiency while reducing costs, waste, chemical spraying, and inhibiting the impact of biotic and abiotic factors on crop stress. Only reliable spatial information makes it possible to comprehend the influence of various factors on the environment. The main objective of the research presented in the paper was to assess the possibility of using maps of vegetation and soil indices, such as NDVI, SAVI, IRECI, CIred-edge, PSRI and HMSSI, calculated on the basis of images from the Sentinel-2 satellite, to qualitatively determine the increased amount of heavy metals in the soil in the areas of small agricultural plots around the Barania Góra nature reserve in Poland. The conducted pilot project shows that the spectral indices: NDVI, SAVI, IRECI, CIred-edge, PSRI, and HMSSI, calculated on the basis of images from Sentinel-2, have the potential to assess the content of nickel zinc, chromium and cobalt in the soil on agricultural plots. However, the confirmation of the obtained results requires continuation of the research.

The mafic-ultramafic terrain of the Bhavani complex in southern India is considered for lithological mapping. The Landsat-8 OLI satellite data was used for the interpretation of different rock types in the study area. The satellite data were digitally processed using ENVI 5.6 image processing software. In the OLI data, excluding bands 8 and 9, the remaining seven bands were used for the generation of colour composite images, band ratios, principal component analysis and SVM classification. Reflectance spectral measurements were carried out in laboratory conditions for five rock samples collected from the study area. The XRF analysis was carried out to estimate the composition of major oxides present in the rock samples. The results obtained from XRF analysis were compared with the rock spectra in characterizing the spectral features of the rock types. The colour composite images (B543, B567, B456, and B457), PCA composite image (PC312 and PC456), band ratios (BR5/5 and BR4/3), colour composite images from band ratios, and SVM classified output are useful in delineation various rock types in the terrain.

The present study aims to delineate the groundwater potential zones (GWPZ) in the Boudinar Basin using geospatial techniques and through an analytical hierarchal process (AHP) method. For multi criteria decision analysis, fifteen thematic layers were integrated into a geographic information system (GIS) environment. In this analysis, each thematic layer is calculated for normalized weights. Furthermore, the consistency index and consistency ratio were calculated to ensure that the result was significant and reliable. The GWPZ map has been categorized into three classes: poor (50.82%), moderate (49.06%), and good (<1.00%). To compare the result, we used four other scenarios of the GWPZ. Two of them are the most similar to our result. Finally, predictive groundwater production and management strategies that ensure long-term sustainability are highly needed.

Opis:
The high global numbers of road accidents due to bad roads and the failure of other engineering structures have necessitated this study, particularly as road transport accounts for a higher percentage of cargo movement in African countries. The geophysical investigation was carried out on six failed and two stable sections along the Ibadan-Iwo-Osogbo highway to examine the geological factors responsible for highway failure in the area. A Landsat ETM+ (Enhanced Thematic Mapper Plus) imagery of the study area and its environs was acquired and processed for lineaments analyses. Magnetic, Very Low Frequency Electromagnetic (VLF-EM) and electrical resistivity methods involving Schlumberger Vertical Electrical Sounding (VES) and 2-D imaging using a dipole-dipole array were utilized. Lineaments were identified across failed localities. Lateral magnetic variations in the near-surface geological materials characterized the study area. The 2-D VLF-EM models generated showed conductive zones corresponding to fractured zones of conductive clay materials within the basement rocks. Subgrade soils below the highway pavement along the failed sections are typical of incompetent clayey and sandy clay/clayey sand formations with resistivity values between 20–475 Ω∙m. In comparison, the subgrade soil beneath the stable sections has moderate to high resistivity values of 196–616 Ω∙m. 2-D resistivity structures across the failed segments identified low resistivity water-absorbing clay and lithological contacts. Water absorbing, clay enriched subgrade soils and the identified near-surface linear conductive features are the major geologic factors, and poor drainage network resulted in the highway failure. Remote sensing and geophysical investigations of the geological sequence and structures underlying the highway should be carried out before construction to effectively complement the routine geotechnical studies to ensure the sustainability of road infrastructure.

Opis:
Agricultural land use and land cover dynamics were investigated in the Araban district of Turkey during the periods 1984–2019 by the use of Remote Sensing and Geographic Information Systems (GIS). Landsat TM and Landsat TIRS / OLI satellite imageries were used to determine land use and land cover changes. Using unsupervised classification method of ERDAS 8.3 software, three main agricultural activities were identified namely irrigated farming, dry farming, and horticultural / garden farming. The analysis has revealed that during the last three decades dry farming has decreased significantly by 14.69% (3802.14 ha) whereas horticultural/garden crops and irrigated farming lands have increased by 11.32% (667.19 ha) and 2.51% (2929.41 ha) respectively. Araban has been under intensive agricultural use due to its fertile soil and preference for horticultural crops such as pistachio, grapes and olives that provide more profit over dry farming crops such as wheat and barley has changed land use. Decrease in dry farming in a semi arid climate where Araban is located, has a potential ecological consequence, including a rapid drop of groundwater level, drying of wetlands and the disappearance of the biodiversity, thus, a necessary measures should be taken to implement an environmentally friendly, sustainable agriculture and settlement plan.

Opis:
Flooding, often triggered by heavy rainfall, is a common natural disaster in Indonesia, and is the third most common type of disaster in Sumedang Regency. Hence, flood-susceptibility mapping is essential for flood management. The primary challenge in this lies in the complex, non-linear relationships between indices and risk levels. To address this, the application of random forest (RF) and frequency ratio (FR) methods has been explored. Ten flood-conditioning factors were determined from the references: the distance from a river, elevation, geology, geomorphology, lithology, land use/land cover, rainfall, slope, soil type, and topographic wetness index (TWI). The 35 flood locations from the flood-inventory map were selected, and the remaining 18 flood locations were used for justifying the outcomes. The flooded areas from the RF model were 28.39%; the rest (71.61%) were non-flooded areas. Also, the flooded areas from the FR method were 8.02%, and the non-flooded areas were 91.98%. The AUC for both methods was a similar value – 83.0%. This result is quite accurate and can be used by policymakers to prevent and manage future flooding in the Sumedang area. These results can also be used as materials for updating existing flood-susceptibility maps.
