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:
The structure of geoinformatics can be understood in many ways, what can be seen from the more or the less complex schemas published in various articles. Geoinformatics creates new possibilities for the precise analysis of spatial phenomena, such as for following their dynamics or defining the associations existing between their components. The use of remote sensing data in such research, takes to another level those areas of knowledge, in which there nevertheless still is a scarcity of reliable materials. It also enables the current monitoring of those phenomena which can't be investigated and estimated in any other way, as well as the modeling of spatial (geographical) phenomena. Since 1996, many studies have been performed at the Laboratory of Remote Sensing of the Environment at the University of Warsaw, in which remote sensing data were integrated with data obtained by other means.

Opis:
Ship motion affects quality of acoustic data collected by various acoustic remote sensing systems used for bottom and fisheries surveying. The angular position of an acoustic beam changes in time from its nominal position vertical to sea surface. This motion affects the acoustic returns from the bottom and other targets by changing their intensity and arrival times. In this paper we illustrate these effects on bottom returns obtained using single beam sonar.

Opis:
Aerial photographs are a source of geological information that may be unobtainable elsewhere. If the fullest use is to be made of this information for the purpose of geological mapping, there must be a planned integration of the photogeological work with the field and laboratory investigations. The appearance of the first satellites for civil purposes on the beginning of the 1970s (such as ERTS – Landsat series), of most land areas of the Earth has provided new opportunity for photogeologists. Many areas can now be studied and mapped geologically for which neither adequate maps nor vertical aerial photograps were available. The advantages of the present satellite systems and examples of their application by specialists of the Polish Geological Institute are presented in this paper. Nowadays, it is practically impossible to imagine performing geological mapping without application of remote sensing data and analysis. Development of new technologies is very fast and new borne techniques are coming like permanent scatter interferometry, laser scanning etc. However, we should always remember, that they are only very useful tools to help geologists in their field mapping art and practise.

Opis:
The Remote Sensing Section of the Committee on Space Research of the Board of the Polish Academy of Sciences (PAS) prepared a report on the state of remote sensing in Poland in the period 2011-2014. The report discusses issues related to the training of specialists in the field of Remote Sensing in first, second and third cycle programmes of study and also major research programmes implemented by the leading Polish research and academic centres. The report was prepared on the basis of contributions provided by members of the Remote Sensing Section PAS: prof. dr hab. Katarzyna Dąbrowska-Zielińska (IGiK), prof. dr hab. Adam Krężel (University of Gdansk), dr hab. inż. Stanisław Lewiński (CBK PAN), dr Marek Ostrowski, dr Piotr Struzik (IMGW-Kraków), and researchers from higher education institutions: dr hab. inż. Kazimierz Bęcek (Wrocław University of Technology), dr hab. inż. Krzysztof Będkowski, (Warsaw Agricultural University, University of Łódz), prof. dr hab. Kazimierz Furmańczyk (University of Szczecin), prof. dr hab. Jacek Kozak (Jagiellonian University), dr hab. Zenon Kozieł (Nicolaus Copernicus University), dr hab. inż. Katarzyna Osińska--Skotak (Warsaw University of Technology), prof. dr hab. inż. Krystian Pyka (Academy of Mining and Metallurgy in Kraków), mgr inż. Paweł Szymański (Warsaw Agricultural University, University of Łódź), dr inż. Piotr Walczykowski (Military University of Technology), dr hab. inż. Piotr Wężyk (University of Agriculture in Kraków), dr hab. Bogdan Zagajewski (University of Warsaw). Prof. dr hab. Jan R. Olędzki, Chair of the Remote Sensing Section during the 2011-2014 term, member of the Committee on Space Research of the Presidium of the Polish Academy of Sciences, handled the editorial work and provided the necessary additions. According to the findings of the Remote Sensing Section, 34 different research institutions and organisations in Poland tackled remote sensing issues in the years 2011-2014. Among them were renowned universities with established traditions in remote sensing studies and those whose history in that regard is slightly shorter, in addition to research institutions, social organisations and commercial companies specialising in conducting various types of scientific and application research. They are listed in alphabetical order below, together with their addresses and websites. Since not all of the institutions submitted their reports, information on their activities can be obtained directly from their websites. Information about remote sensing activities was obtained from 30% of the institutions and organisations involved in this area of study. It should be noted, however, that these institutions are the most notable in the field in Poland. The submitted information reveals that at least 215 people were directly involved in remote sensing activities or collaborated with remote sensing teams. They implemented 128 research projects and published a total of 404 studies at home and abroad. In addition, 154 graduates were awarded MA degrees, 17 - PhD degrees; 6 were awarded postdoctoral degrees (doktor habilitowany) and one was awarded the title of professor. Tables 1 and 2 below show a summary of achievements of academic and research institutions. In the next part, the report presents detailed data on the institutions from which information was obtained: universities, research establishments, business organisations and NGOs.

Opis:
Drought is a natural phenomenon as it often occurs in the area of Yasothon province, northeastern of Thailand. It causes effects on vegetation condition in the area. Drought information might be useful for local government to prepare for prevention and mitigation plan in the future. For this reason, the primary objective of the research was to conduct the examination of this province to find severe drought years. Firstly, the researcher needed to find Normalized Differences Vegetation Index (NDVI) and Vegetation Condition Index (VCI) by analyzing monthly Landsat data acquired at different periods of time from January to December 2014, 2015, and 2016, covering 4,096 km2. Then, the researcher needed to find relationship between VCI and monthly rainfall represented in term of space and time. As results, VCI and its relationship with monthly rainfall were congruent. VCI showed that the drought area was 33.87% or 1,387.32 km2 of studied area in 2014, 16.24% or 665.19 km2 of studied area in 2015 and 27.95% or 1,144.83 km2 of studied area in 2016. Therefore, the most and the least severe drought years were 2014, 2016, and 2015 respectively.
