About the problem of identifying rural of the same name in russian documents of the XVI–XX centuries and the tools to research it
Authors: Krassowski Anton
Published: December 2024

The historical cases of the existence of jointly accounted rural with the same names in settlements are considered, and the reasons that led to a change in the number of such rural areas are also revealed. The historically used methods of resolving the ambiguity of identifying rural settlements with the same names are analysed. It is shown that this was achieved by taking them into account among smaller accounting units, by indicating their locations relative to local objects of natural or anthropogenic origin as well as indicating their other specific features. It was found that the methods of identification of rural with the same names used in the materials compiled by various departments could be different. Identification could be provided by: grouping objects by accounting units, indicating their distinctive features and locations relative to local objects, as well as by forming unique names for rural settlements that were previously of the same name. Cases have been identified in which certain identification methods could be used. It is shown that this could depend on the department in which the documents and cartographic materials were compiled (secular or spiritual; metropolitan, provincial or county); on the circle of persons who compiled the documents (their profession and type of activity); on the form of existence of the materials (hand-written or printed); on the number of settlements simultaneously taken into account in them (several tens or several thousand); depending on the number of copies of documents (several units or whole copies) and other circumstances. Based on the performed analysis, recommendations have been developed for finding places to store information about rural settlements in problematic cases. The research was performed using the Big Data tool on the example of 8 rural settlements of the Ruzsky district that had the same names at different time intervals of the XVI–XX centuries. It is shown that the use of the Big Data tool makes it possible to carry out research in this direction. The results of the presented research may be in demand by specialists searching for information about rural settlements of the XVIII–XX centuries in historical sources, researching the history of the Ruzsky and adjacent counties, as well as working in the fields of the history of surveying and the history of cartography.
The spread of christianity in Abkhazia according to the spatial analysis of monuments in GIS in the late antique and medieval periods
Authors: Trebeleva Galina , Sakania Suram
Published: December 2024

The article is devoted to the analysis of the spatial location of temples in Abkhazia and reconstruction based on the results of the ways of penetration and spread of Christianity in different chronological stages: the period of late antiquity and the first penetration of Christianity into the territory of Colchis (IV–V centuries); the period of maximum Byzantine influence in the era of Justinian the Great and the period that following it (VI–VII centuries)—the period traditionally considered the stages of the official adoption of Christianity in Abkhazia; and the period of the maximum flourishing of the Abkhazian kingdom. The analysis is carried out on the basis of a GIS created by the authors, according to field surveys, including 149 temples. The conducted spatial analysis allowed us to answer the questions of how quickly Christianity began to spread across the territory of Abkhazia, which areas turned out to be the most susceptible to the new religion. It was traditionally believed that Christianity entered Abkhazia with the Roman military, through the fortresses of the Pontic Limes, built along the coast. However, the analysis showed that the trade caravan routes were also an important way of spreading Christianity. For the same reason, we see several hotbeds both in the west of the republic and in the east. But in the center, where the Bzyb ridge blocks access to the main passageways, traditional religion has been preserved for longer, almost two centuries. This factor influenced the spread of Christianity in the subsequent period. In general, the Justinian period was characterized by a significant increase in the number of churches, on the one hand, the standardization of its external form, on the other, and on the third, the complication of the liturgical service, which was reflected in the more complex organization of the internal space of churches. In the subsequent period, these trends are intensifying. Separate architectural schools are emerging. Thus, the spatial analysis of both the location of temples and the distribution of certain architectural features in space reflect the processes of Christianization and development of the Church, which was not reflected in written sources.

Published: December 2024

In 2023 there was a severe forest fire on the territory of the Semipalatinsk Forest. More than 60 thousand ha were burned. This resulted in high environmental costs, destroying trees, real estate, recreational and even human lives. One of the most pressing issues was the determination of the origin and spread of forest fires. In such cases, remote sensing data is a spatial and temporal measure to obtain fast and accurate data to prevent the further spread of the fire and to neutralize this natural disaster. Using such geospatial information, it is possible to prioritize preventive measures to reduce the risk of forest fires and identify mitigating factors to increase the likelihood of immediate fire suppression in threatened areas. This work proposes to assess the fire potential and to determine the hazard potential. This is done by analyzing and mapping the area of the fire that has occurred. The mapping of the fire potential was approached from a remote sensing point of view by estimating and mapping the total vegetation cover using Landsat-8–9 OLI/TIRS DATA and the geographic information systems QGIS, SAGAGIS. A morphometric, spatial analysis of conditions was also conducted, taking into account many factors affecting fire potential—land exposure, aspect, wind direction, fire statistics, population density, climatic characteristics, etc. As a result, an attempt was made to create indices RBR, RdNBR, dNDVI, dGNDI, GEMI and BAI, which could be the basis for the determination of fire potential. These indices are based on the type of tree, the vegetation and the topographic features. These characteristics make it possible, after the classification of the Landsat images, to evaluate the reliability of the information obtained by determining the area of the fire through the Object Based Image Analysis segmentation method and by assessing the accuracy of the detected data. The index values identified were consistent with reliable information for identifying fire locations and monitoring estimated fire risk. They could be used to map fire potential from regional to local scales.
Remote sensing data analysis of geological environment components for the purposes of karst hazard assessment in the territory of the Mezmai–Lagonaki road construction site (Krasnodar region)

Published: December 2024

During carrying out comprehensive survey at the construction site of the road connecting Mezmay village with the existing road Lagonaki plateau–Dakhovskaya village (Krasnodar region), satellite images from the Google Earth program having sufficiently high resolution were used, which made it possible to assess the risk and danger of karst processes at the pre-design stage. The purpose of the research is to make design decisions for the normal construction process in the territory with developing karst processes. The article clearly shows how the use of satellite imagery, laser scanning data and maps of the road construction site provides for identification of the most important components of geological environment and factors contributing to development and activation of karst processes. Using LIDAR scanning of the study area it was possible to “remove” the upper forest layer (cover) and expose the relief of the site, determining size, shape and number of karst manifestations. This allowed performing preliminary assessment of the mechanism of the karst process that formed numerous depressions. These landforms are primarily formed not by sinkholes, but by corrosionerosion processes. That is, the development of karst funnels on this section of the projected road does not fall under the “standard” methodology for assessing karst hazard described in the SP. The reconnaissance of the road route and the inspection of karst funnels on the spot fully confirmed the above assumption. Indeed, all studied depressions in limestones of the Jurassic age had a corrosion-erosion origin. Thus, on the basis of the conducted engineering survey and karstological studies, the conclusion is formulated that during the construction and reconstruction of the road anti-karst measures are not required. A set of anti-erosion measures and monitoring of the state of the road is required instead.

Authors: Kartsan Igor , Zhukov Aleksandr , Skripachev Vladimir
Published: December 2024

In full accordance with the observed intensive growth of the global market for products and services based on space-based information provided by space-based Earth observation assets, satellite missions and space-based Earth remote sensing technologies are currently undergoing rapid development. Space images are important for monitoring emergency situations: floods and inundations, forest fires and earthquakes. A wide range of Earth remote sensing satellites equipped with many types of target equipment are used to obtain all that information. In the course of developing the design of a space-based operational data transmission system, which is based on a heterogeneous orbital constellation using a network of relay satellites, it is necessary to model the ballistic structure of the Earth remote sensing orbital constellation. The efficiency of Earth remote sensing information delivery to consumers should be considered under various options of building a network of relay satellites, taking into account the characteristics of existing and prospective high-speed radio lines of satellites. During modeling it is also necessary to take into account that in the case of a single repeater satellite the best picture on the minimum times of information delivery efficiency from the Earth remote sensing satellite is observed for a low-orbit repeater satellite, and the best picture on the maximum times of information delivery efficiency from the Earth remote sensing satellite is observed for a geostationary repeater satellite. An algorithm for model formation of an orbital constellation of different types of satellites with given initial ballistic characteristics is created. The presented algorithm consists in sequential calculation of initial conditions of reference satellites for each plane, and then, according to the initial conditions of the reference satellite, calculation of initial conditions of other satellites of the given plane.

Published: December 2024

The article discusses the use of GIS technologies in the study of avalanche activity in the East Kazakhstan Region. The research results presented in the article were obtained at the first stage of the survey of the territory of the region according to various factors and criteria that may be important for the level of avalanche activity in the region. Earth remote sensing (ERS) data is necessary for the development of avalanche hazard monitoring systems and scientific substantiation of the placement of sensors of the system on avalanche-prone slopes. The first step in this research is to build a digital elevation model (DEM) using SRTM data. The paper then provides an overview of the atmospheric precipitation identification methods used in the research. These methods are based on the use of optical remote sensing data, which includes the assessment of special indicators and indices. The following indicators were considered: the NDSI index for assessing the coverage of the Earth’s surface with snow or glaciers; the CHIRPS and GSMaP dataset for assessing climatic hazards associated with precipitation; data from the ERA5 reanalysis of the European Center for Medium-Range Weather Forecasts ECMWF to assess the climate and weather over the past few decades in the East Kazakhstan Region. In addition, to understand the characteristics of the underlying surface affecting spontaneous avalanches in particular, the NDWI index to assess the moisture content of the studied area. Based on the results of historical satellite data from Sentinel-2 images, various digital models were built for the East Kazakhstan Region based on the above-mentioned indicators. These models were used at the first stage of assessing the territory of the region by climatic characteristics to further create higher-resolution digital models for the most problematic avalanche-prone areas.
Comparative dynamics of individual glaciers of the latitudinal transect (Kodar–Himalayas)
Authors: Kitov Aleksandr , Plyusnin Viktor
Published: December 2024

Landsat remote sensing data make it possible to analyze the state of nival-glacial objects in various areas of modern glaciation with a periodicity of up to 5 years. One of the indicative and well-decipherable characteristics of such objects is the open area of the glacier. The latitudinal transect from the northern glaciation regions of Southern Siberia to the Himalayas makes it possible to present the dynamics of glaciers on the example of individual glaciers of key regions from this perspective with a five-year periodicity. Along the transect, the dynamics of glaciers in the mountains is shown: Kodar, Barguzinsky Range, Baikal Range, Eastern Sayan (Topografov Peak and Munku-Sardyk massifs), Mongolian Altai, Tien Shan, Himalayas. An analysis of changes in the open part of the glaciers of some representatives of these mountains is given. Throughout the transect, glaciers shrink, but to varying degrees. There is a decrease in glaciers and an increase in the intensity of surface moraine armor to a greater extent in the northern part of the transect. Based on the data of remote sensing of the Earth (Landsat), a comparison of the dynamics of the selected glaciers Azarova (No. 20, Kodar), Urel-Amutis (Barguzinsky Ridge), Chersky (Baikal Range), Peretolchina (No. 31, Munku-Sardyk), Topografov (No. 18, Okinsky Ridge), Tsast-Ula (No. 8, Tsambagarav), Karlygtag (Tien Shan), Altyntag (No. 3, Kunlun) and Yubra (No. 30, Langtang) was carried out. From the mid-1970s, when Landsat imagery began, to the present day, glaciers have shrunk in area from 17 to 63 percent. The glaciers of the northern part of the transect are shrinking more smoothly compared to the southern part. In the southern part, there is a reduction and slowdown, and sometimes an increase in the open part of the glaciers with a periodicity of about 10 years. The Himalayan glacier has the most uneven dynamics. The rate of glacier shrinkage decreases from south to north of the transect. The Azarova glacier is shrinking at a rate of 0.007 km2/year, the Urel-Amutis glacier is shrinking at a rate of 0.005, the Chersky glacier is shrinking at a rate of 0.002, the Peretolchina glacier is shrinking at a rate of 0.012, the Topografov glacier is shrinking at a rate of 0.002, the Tsast-Ula glacier is shrinking at a rate of 0.056, the Altyntag glacier is shrinking at a rate of 0.013, the Karlyktag glacier is shrinking at a rate of 0.07, and the Yubra glacier is shrinking at a rate of 0.085.
Mapping of forest disturbance from winds of extratropical cyclones in the southern part of Sakhalin by remote sensing data
Authors: Melkiy Vyacheslav , Verkhoturov Alexey
Published: December 2024

Deforestation was named one of the global environmental problems by the close of the 20th century. Tropical cyclones, which operate in the Northern-West Pacific during the summer and autumn and sometimes go far north, transforming into extratropical cyclones, are the main cause of damage for forest areas in Southern Sakhalin. In central parts of tropical cyclones, during their maximum development, pressure reaches 895 mbar, stable winds arising in atmospheric vortex can have speed up to 50 m/s, and gusts have speed up to 78 m/s. Storm winds with gusts have speed over 35 m/s, which are capable of knocking down free-standing trees, as well as causing significant damage to the forests. In October 2015, in the southern-west part of Sakhalin during the passage of typhoon Choi-wan, significantly forested areas were disrupted by winds. The purpose of the work was to investigate the extent and nature of damage to the forest, caused by winds during passage of extratropical cyclones over territory of the South-West of Sakhalin Island. Images of the research area were classified by “with training” method. The training sample was made up of a set of pixels representing images of sample plots, where geobotanical research was performed. It was revealed that total area of windthrows in the territory of Kholmsky and Nevelsky districts in south-west part of Sakhalin Island was 22 735 ha. To analyze character of windblow damages in researched area, the Normalized Difference Vegetation Index was calculated and areas with varying degrees of damage were identified in terms of content of phytomass, presented in form of green trees and clumps, as well as preserved underscrub and undergrowth. At the same time, it was revealed that among the affected stands, one can distinguish completely dead (occupy 19.85 % of the territory), partially damaged (41.85 %) and slightly damaged (38.29 %). Mapping forest disturbance from winds by remote sensing data after passing over territory of tropical cyclones makes it possible to quickly assess the disaster scale, as well as adjust reforestation plans for the coming few years. If using geoinformation technologies for processing data, time of work is significantly reduced.
Assessment of the accuracy of the sea surface temperature of the Baltic sea
Authors: Zakharova Ekaterina , Fomin Vladimir
Published: December 2024

The paper presents the results of a comparison of satellite sea surface temperature (SST) processing level L3S (SST L3S) and L4 (SST L4) with contact measurement data from 41 stations located in the coastal part of the Baltic Sea. Mean absolute deviation (MAD) of SST L4 and L3S, respectively, varies from 0.6 and 0.59°C in March to 2.0 and 2.17°C in May, and the whole year average MAD is 1.27 and 1.37°C. The SST L4 and L3S bias overall year is -0.08 and -0.09°C, however, consideration of the monthly average values allows us to trace significant variability during 2018. The SST L4 and L3S bias, respectively, varies from -0.85 and -1.11°C in May to 0.84 and 1.1°C in December, bias has a pronounced seasonal variation and heterogeneity over space. SST is underestimated from February to June and overestimated from July to December near the coastline of the Baltic Sea. The largest MAD in all seasons of the year are observed at stations on the eastern coast of the Gulf of Bothnia, at the entrance of the Gulf of Finland, near the island of Saaremaa and in the Gulf of Riga. The SST L4 data has higher accuracy compared to the SST L3S data, while the SST difference is negligible and in both arrays the largest bias and MAD are observed in the coastal zone.

Published: December 2024

This work presents experience in the combined use of high-precision positioning methods and standard post-processing programs. This is necessary to provide geodetic support for aerial photo-geodetic work during engineering surveys in the oil and gas sector—to determine the coordinates and heights of control points using the example of an extended linear structure located in difficult physical and geographical conditions in the area of the Baikal-Amur Mainline. To solve the problem of refining the standard geoid model, based on the values of the normal heights of the starting points, using geoinformation technologies in GIS with open object code QGIS, a local spatial geoinformation correction model was created. This is a model of the surface of the difference between the normal and ellipsoidal heights of the starting points, obtained in the coordinate systems of the work object for the entire site. Analysis of the results of the work showed that modern GIS with their mathematical apparatus and geographic information technologies make it possible to create local geoid models that fully correspond to the characteristics of the work area. They are necessary because the post-processing programs used contain a standard geoid model that does not take into account local factors of geoid change for specific territories. The use of the proposed method can significantly simplify logistics processes when performing geodetic work, without reducing their accuracy at the same time. At all stages of the work, the capabilities and tools of modern geographic information systems and technologies were used, allowing for the effective comparison of engineering survey data and assessment of the accuracy of topographic and geodetic work.
Assessment of change in vegetation cover of the territory of Greater Moscow over twenty years using satellite images
Authors: Markova Olga , Gunya Alexey , Purekhovskii Andrey
Published: December 2024

The article presents the results of a study of the dynamics of woody vegetation in the territory of Greater Moscow over twenty years (2000–2020). Using Landsat ARD remote sensing data and geoinformation technologies, a series of maps of growth and loss of woody vegetation were constructed based on reflectivity values, brightness temperature, and vegetation indices. When calculating the areas of forests and fields, it was found that over 20 years their area has slightly increased overall. It was found that the increase in woody vegetation in Old Moscow is characteristic mainly of residential areas close to the Moscow Ring Road. In TiNAO, the maximum increases in woody vegetation are evenly distributed across the districts. In nature protected areas, as a rule, there is no significant increase. Losses of woody vegetation in protected areas are associated with their landscape transformation and construction of various structures. The greatest forest losses are observed in the residential areas of Old Moscow, not directly adjacent to the Moscow Ring Road. In New Moscow, there are lines of transport arteries and areas oriented towards development. Of the specially protected natural areas, the greatest forest losses are typical for the Losiny Ostrov National Park. Of the natural and historical parks, Izmailovo, Kuzminki-Lyublino, Tsaritsyno, and Moskvoretsky Park suffered the most. The territories of the specially protected natural areas are mainly characterized by the stability of their tree stands, not distinguished by either strong growth or large losses. An assessment was made of changes in the areas of forest growth and loss in the city as a whole by tree height categories, which found that the greatest growth is typical for categories 5, 7, 9–13 m, and the greatest losses are for categories 12, 18, 19, and 21 m. The territories where the tree height did not change also have a small share in the city area (about 1.5 %). The data obtained can be recommended for studying the history of the city, developing urban planning and environmental protection measures.

As in every developing country,
Madagascar is still fighting against the tuberculosis
(TB), the second leading cause of death from a
communicable infectious disease. Its incidence
remains high, exacerbated by limited medical
infrastructure and unequal distribution of health
resources. Several researches were conducted to
automatically diagnosis disease to greatly lowering
the total expenses. Deep learning approaches
demonstrated its high effectiveness in the domain
using chest x-ray images (CXR) that are the most
cost-effective and widely utilized imaging
technology to classify TB. Some preprocessing was
necessary for getting better features from the
images. Using a more lightweight model inspired
by SSD Lite X, this work achieves the highest
accuracy (training, validation and testing), recall,
F1-Score and specificity of 100% each, making this
model the most effective one in the state-of-the-art.
It could be deployed in a low-resource
environments, enabling automated diagnosis in
every region of Madagascar and other developing

A Deep Neural Network Approach for Optimizing Economic Load Dispatch in Power Systems
Authors: Gihare Sonam , Pachori Prof. Arun
Published: December 2024

To ensure minimization of power
losses as well as economic feasibility of electrical
power generation, economic load dispatch happens
to be one of the most challenging optimization
problems which is faced in electrical engineering.
With the advent of distributed power systems, an
interconnection of power systems generating from
different sources have come into consideration.
However, all sources do not operate in the same
manner and hence the generation cost for different
sources varies significantly. Economic Load
Dispatch (ELD) can be defined as a technique to
schedule the power generator outputs with respect
to the load demands, and to operate the power
system in the most economical way. This paper
presents a neural network model for implementing
economic load dispatch for a three as well as six
generation system. The load is also varied for both
the 3 and 6 generations systems. The results clearly
indicate that the cost of generation increases with
the increase in load, which is also intuitive and
hence gets tested. Thus the proposed model can be
used to implement an optimized economic load
dispatch mechanism for multi-unit power systems
which is a typical characteristic of distributed
power systems.
Impact of Chikoko Calcination Temperature on the Compressive Strength Properties of Blended Concrete
Authors: Overo K.E Overo K.E , Gilbert Damini Righteous
Published: December 2024

The environmental impact of the cement industry
necessitates the exploration of sustainable
alternatives, such as supplementary cementitious
materials (SCMs). Chikoko, a clay material from
the Niger Delta, has shown potential as an SCM
when calcined. This study investigates the impact
of calcination temperature on the compressive
strength of concrete blended with Chikoko. A total
of 375 Samples were prepared with Chikoko
calcined at temperatures ranging from 0°C to
800°C and cured for 7,14,21,28, 56 and 120 days.
The results reveal that higher calcination
temperatures significantly enhance compressive
strength across various curing ages. At 200°C,
concrete incorporating 10% Chikoko shows a
60.82% strength increase. At 400°C, the strength
improvement reaches 93.51% at 7 days, indicating
robust early strength development. Calcination at
600°C further enhances strength, with a 4.59%
increase at 120 days. The highest improvements are
observed at 800°C, with a 10.46% increase at 28
days and 7.39% at 120 days. Optimal Chikoko
concentration consistently falls around 10%. The
study concludes that higher calcination
temperatures and longer curing times significantly
boost compressive strength, providing valuable
insights for optimizing the mechanical properties of
Chikoko blended concrete in construction
applications.
Mechanical Performance of Concrete with Partial Fine Aggregate Replacement Using Pulverized Waste Glass Bottles: A Comparative Study of Mix Grades
Authors: Awanu Timothy Omotoyosi , Righteous Gilbert Damini
Published: December 2024

This study investigates the mechanical performance
of concrete incorporating pulverized waste glass
(PWG) as a partial replacement for fine aggregates
in two distinct mix ratios: 1:1.5:3, representing
higher-grade concrete, and 1:2:4, representing
lower-grade concrete. Compressive strength tests
were conducted at 7, 14, and 28 days on concrete
samples with PWG replacement levels of 0%, 10%,
20%, 50%, 75%, and 100%. The results reveal that
higher-grade concrete, with a greater reliance on
aggregate interlocking and matrix bonding, is more
sensitive to PWG content, showing significant
reductions in compressive strength at a 100%
replacement level. However, moderate replacement
levels, specifically up to 75%, did not substantially
affect long-term compressive strength, suggesting a
tolerance for partial substitution in higher-grade
mixes. In contrast, lower-grade concrete exhibited a
notably positive response to PWG replacement,
particularly at 75%, where compressive strength
reached a peak of 32.15 N/mm². This outcome
indicates that PWG can enhance the packing
density of lower-grade mixes, compensating for its
lack of angularity and bonding characteristics
compared to natural aggregates. These findings
underscore the potential of PWG as a sustainable
and effective alternative to fine aggregates,
particularly suited to applications in lower-grade
concrete, while maintaining mechanical
performance standards.
