![The schematic diagram of robust height mean (adapted from [16]).](publication/358206449/figure/fig5/AS:11431281212464871@1702641798375/The-schematic-diagram-of-robust-height-mean-adapted-from-16_Q320.jpg)
Building change detection using remote sensing images is significant to urban planning and city monitoring. The height information extracted from very high resolution (VHR) satellite stereo images provides valuable information for the detection of 3D changes in urban buildings. However, most existing 3D change detection algorithms are based on the...

... The rapid development of remote sensing allows aerial and satellite images, including orthoimagery, to be used in order to monitor changes in the area of lakes and artificial water bodies [46][47][48]. In studies of transformations of aquatic environments, including studies of lakes and other bodies of water, aerial photographs and satellite imagery have become a primary source of data on the functioning of these ecosystems and the impact of human pressures on the aquatic environment [49][50][51][52][53]. Studies based on the interpretation of aerial photographs or satellite imagery are often conducted with respect to environments where field surveys are not feasible due to the difficulty of accessing the studied objects or the high cost of conducting in situ work. ...
The Silesian Upland in southern Poland is known as a place where subsidence processes induced by mining activities occur in an area of nearly 1500 square kilometres, with many water bodies that formed in subsidence basins. This study concerned the dynamics of changes in the occurrence, boundaries and area of water bodies in subsidence basins (using orthoimagery from 1996 to 2023), as well as the assessment of the factors underlying the morphogenetic and hydrogenetic transformations of these basins. Within the subsidence basins covered by the study, water bodies occupied a total area that changed from 9.22 hectares in 1996 to 48.43 hectares in 2003, with a maximum of 52.30 hectares in 2009. The obtained figures testify to the extremely dynamic changes taking place in subsidence basins, which are unprecedented within such short time intervals in the case of other morphogenetic types of lakes and anthropogenic water bodies (for instance, from 1996 to 2003, the basin of the Brantka water body in Bytom underwent a more than two-fold change in its area, with RA values in the range of 54.4% to 131.9). A reflection of the dynamics of short-term changes in the water bodies in question in the period from 1996 to 2023 is the increase in the water area of the three studied water bodies, which was projected by linear regression to range from 0.09 hectares/year to 0.56 hectares/year. The area change trends, as determined by polynomial regression, suggest a slight decrease in the water table within the last few years, as well as within the next few years, for each of the studied basins.
... The use of archival and contemporary aerial photography is a method offering valuable information on past or baseline landscape conditions, making them useful for mapping, understanding, and monitoring change over time [80][81][82]. Images of this type have been used for many decades in scientific research in a variety of approaches, including, but not limited to, observations of the transformation of urban structures [83][84][85], including on the basis of comparisons of historical and contemporary images [86], land use and land cover transformations [64,87,88], and landscape ecology and transformation [80,[89][90][91][92][93]. Significantly, there is a publication presenting the results of a land cover structure study based on aerial photographs for Gorlice. ...
... It is sometimes the case that the format, scale, and extent of the images vary from one series of so-called air raids to another, presenting smaller or much more extensive sections of the photographed space. The assembling of these photographs into all-encompassing images, taking into account minor shifts due to the changing position of the aircraft as well as the curvature of the globe, is fraught with the risk of certain inaccuracies, as pointed out by many other researchers [79,88,126]. Older photographs tend to be in black and white, with later photographs in colour. ...
The article presents the spatial-functional transformations of a medium-sized post-industrial city in the context of the decline in the industrial function which used to occupy a prominent position in the city. The research attempts to answer the following questions: (1) What has been reflected in the spatial and functional development of the city and its landscape by the dynamic transformations in the industrial sector that have taken place since the 1970s, playing out in the broad context of the specific political and socio-economic conditions? and (2) how is the city dealing with post-industrial sites—are we dealing with a ‘post-industrial scar’ or a process of their adaptation to the needs of the present? Analyses were initiated to identify differences in spatial and landscape structure from 1966 to the present. To this end, a land cover analysis was carried out based on available sets of aerial photographs taken in four selected years within the study period, as well as a calculation of the index of variation. Graphical and GIS software (QGIS 3.28.4 version) and methods of statistical data analysis were used. To come up with a full picture of transformations in the second half of the 20th century, an outline of the historical spatial development of Gorlice and the local oil and engineering industry was presented. The results of the research confirm the relationship between the functional and spatial development of the city and the transformation and condition of its industrial function.
... During the creation of orthophoto maps, standard activities were carried out, according to known and adopted methods such as preprocessing of historical aerial images (scanning, cleaning and improving the quality), determination of missing parameters of internal and external orientation (flight height, overlap, flight direction, fiducial marks), triangulation of aerial images, terrain extraction, orthophoto mosaicking, 3D-feature collection and GIS analysis [11,12]. Geological mapping for each of the mentioned epochs was carried out through the processes of 3D photogrammetric processing using dedicated software and standard methods and approaches, as well as modern trends such as alignment of scanned images, camera calibration, dense point cloud generation and classification, building DEM and orthomosaic generation and finally building a stereo 3D model for use in content mapping [13][14][15][16]. ...
... Scanned images in their original state could not be used as a measurement base due to deformations caused by the central projection, the nonverticality of the image and the different heights of the terrain and features on it [12]. Therefore, it was necessary to perform orthorectification of each individual image [1,16]. ...
... The applied methods can be categorized as manual, semiautomatic and automatic, based on the extent of the necessary intervention of the analyzing process [15]. In the next step, the method of primary processing of images, i.e., photogrammetric processing and analysis of the subject images, was applied, as it is in the case of the Bovan lake study, where historical aerial photographs were used for monitoring environmental changes [16]. At this stage, numerous problems arose. ...
The application of remote sensing methods provides useful information that can be used for numerous research. Thus, spatial changes in soil, vegetation, hydrography and such can be analyzed. By analyzing the data obtained by remote sensing methods, high-quality and important data can be obtained for monitoring changes in soil movement caused by landslides. This method provides the possibility of determining the state of the observed space over a longer period of time. Historical aerial imagery has a high level of spatial detail analysis. Comparative analysis of the aerial imagery from the past, recent ones and other surveys can certainly provide information on the trend of ground movement, as well as lead to conclusions for taking specific measures. The present paper gives an example of the analysis of the particular area of the “Umka” landslide based on historical surveys. The “Umka” landslide is located along the right bank of the Sava River near the city of Belgrade, which, with its long-term activity, jeopardizes residential buildings, infrastructure facilities and the population that still lives on it.
