Assessment of flood susceptibility utilizing remote sensing and geographic information systems: A case study of Mpazi sub-catchment in the city of Kigali
type: item
description: The Mpazi sub-catchment has been facing recurring floods, which pose significant threats to the community and environment. However, GIS technology has proven to be a valuable tool in assessing flood risks and vulnerability in the region. By analyzing spatial data such as land use, elevation, and rainfall patterns, detailed flood maps can be generated to simulate flood scenarios and develop effective management plans. The study conducted in this region revealed that there is a high susceptibility to flood hazards, particularly during the rainy season. The study identified the most vulnerable areas in the region and categorized them as follows: very high risk (39.74%), high risk (13.02%), moderate risk (30.22%), low risk (5.12%), and very low risk (11.9%). It is important to note that floods not only impact the environment but also infrastructure, such as residential and commercial buildings. The insights provided by this study are invaluable for stakeholders in developing effective flood management strategies to mitigate. Hence, all concerned government departments and citizens should collaborate actively to alleviate the ongoing rise in flooding and its impact. Adherence to land use and zoning regulations is crucial in this regard to address the issue effectively.

A geo-spatial analysis of precipitation distribution and its impacts on vegetation in Rwanda
type: item
description: Rwanda is home to a diverse and picturesque landscape that encompasses a range of ecosystems, including rainforests, savannas, and agricultural regions. The intricate relationship between rainfall patterns and vegetation types shapes these varied landscapes, which are crucial for supporting biodiversity and agricultural productivity across the country. Our comprehensive geospatial analysis employs advanced geographical information systems (GIS) techniques and remote sensing data to assess spatial and temporal variations in precipitation across distinct regions of the country. Utilizing historical precipitation data and satellite-derived vegetation indices, our analysis spans extensive periods, incorporating annual and monthly rainfall records from 1990 to 2020 and MODIS/Terra Vegetation Indices spanning 2000 to 2020. Advanced remote sensing methodologies are employed to investigate the correlations between precipitation patterns and vegetation dynamics. The study reveals discernible spatial variations in Rwanda's precipitation distribution, elucidating marked seasonal fluctuations. Identified regions experiencing notable changes in precipitation levels exhibit a direct impact on vegetation health and density. Recorded annual rainfall data illustrates variations across different years, indicating fluctuating levels such as 1160.1 mm (1990), 1078.2 mm (2000), 1402.4 mm (2010), and 1391.1 mm (2020). Corroborating NDVI imagery demonstrates increased vegetation cover in 2010 and 2020, aligning with higher recorded rainfall during these years. The research underscores the significance of these findings in understanding the intricate interplay between precipitation distribution and vegetation dynamics and offers actionable insights essential for sustainable land management, optimized resource allocation, and the formulation of resilience-building strategies. These insights are particularly crucial in the context of adapting to and mitigating the effects of climate change.

Land use and land cover classes affected by the possible sea level rise in Mersin city center (Türkiye)
type: item
description: In this study, a sea level rise (SLR) investigation was carried out in an area representing the Mersin city center located in the south of Türkiye. The study area covers an area of ca. 385 km2. Future projections provided by the Intergovernmental Panel on Climate Change (IPCC) were used for the SLR assessment. These projections are for the years 2100, 2200, 2300, 2400, and 2500 and the SLR for these periods are 0.83 m, 2.03 m, 3.59 m, 5.17 m, and 6.63 m, respectively. It is aimed to determine the areas affected by the SLR that will occur according to these projections. In this context, land use and land cover (LULC) data were obtained from the CORINE 2018 dataset. The data obtained were adapted within the boundaries of the study area and processesed using various GIS analyses. The results have shown that all LULC classes are greatly affected by the SLR, but in varying degrees. Land losses as a result of SLR are as follows: 0.4% at 0.83 m SLR, 9.8% at 2.03 m SLR, 16.7% at 3.59 m SLR, 21.6% at 5.17 m SLR, and 25% at 6.63 m SLR.

Comparative evaluation of the performance of different regression models in land valuation
type: item
description: Lands can play a dominant role in the real estate market, especially due to their legal zoning rights. These properties are preferred investment options compared to financial instruments due to factors such as high returns and long-term reliability. Today, Machine Learning (ML) algorithms are used to accurately determine the land value. Regression models, capable of handling complex relationships, integrating Geographic Information System (GIS), and providing a comparative approach, lead the way among these algorithms. In this study, Lasso, Elastic-Net, ML.Net, and Ordinary Least Squares (OLS) regression models were employed to predict land values in the central neighborhoods of Konya's Selçuklu, Meram, and Karatay districts. The datasets containing legal, physical, spatial, and local criteria of 440 lands were obtained, and GIS analyses were conducted to prepare the spatial data. Based on the modeling results, it can be observed that ML.Net exhibited successful performance with metric values of MAE=0.043, MSE=0.005, RMSE=0.060, and R2=0.82. Comparatively, ML.Net's 9% superior performance compared to the commonly encountered OLS in the literature is of significant importance. The results demonstrated the usability of various regression models for land valuation and highlighted that ML.Net can yield improved outcomes, particularly in modeling high-market-value lands.

Wildfire hazard and risk assessment: The case of Gabala district
type: item
description: As one of the main natural resources for humans, protection of forest resources is one of the main ecological problems of the world. Forests are a source of oxygen, as well as they have some features that can ensure ecological balance. For example, forests are one of the major factors that prevent landslides, erosion processes, flood events, as well as protecting land resources, hydrological resources and optimization micro climatic condition. Decreasing of forest stock affects the fauna directly. There are some factors that impact decreasing of forest resources, for example, settlements, industry and forest supply and etcetera. Forest fires occurring in different parts of the world every year eradicated acres of forest stock. The formation of forest fires is influenced by factors such as climate, anthropogenic and topological effects. Research area is district of Gabala, which is situated at south slopes of Greater Caucasus. Gabala is distinguished by the abundance of forest resources in the territory of Azerbaijan, which is poorly provided with forest reserves. 32405.15 hectares of this district are covered with forests. Taking into account that 40% of the fire incidents that occurred on the southern slope of the Greater Caucasus in 2021 and 2022 took place here, this place was taken as a research area. Wildfire hazard and risk assessment and fire risk zonation, anthropogenic and topological effects are considered in this article and mapping had been done. The resulting values were classified according to the risk group and the results were compared with the fire area data. As a result of the comparison, was not found fire process in the categories of no risk or low risk. 90% of fire incidents could be classified as medium risk, high risk and critic high-risk categories. Consequently, this is an indicator of the validity of the selected parameters and the conducted assessment.

Determining temporal and spatial changes in air quality in the city of Nevşehir
type: item
description: Air pollution, which has notably surged from the Industrial Revolution onwards, has had adverse effects on all forms of life, primarily humans. Factors such as urbanization, intensified industrial activities, growing production and consumption, and the proliferation of vehicular traffic have significantly contributed to the escalating impact of air pollution. This study aimed to evaluate the levels of particulate matter 2.5, particulate matter 10, and carbon dioxide across diverse locations within Nevşehir city center. Sampling was conducted at ten distinct points, utilizing the CEM DT-9880 device for particulate matter and the EXTECH Easyview 80 CO2 Analyzer device for carbon dioxide. Measurements were taken during both morning and evening hours to discern daily fluctuations, as well as in both summer and winter to identify seasonal variations. Data collected were input into QGIS software and interpolated to delineate the distribution of pollution throughout the city. The findings reveal that pollution levels are significantly elevated across the city, particularly in industrial zones, organized industrial districts, and densely populated residential regions, as well as in areas where coal is extensively utilized for heating. Conversely, parks and green spaces exhibit the lowest levels of particulate matter and carbon dioxide pollution. While complete eradication of pollutants may be unattainable, it is crucial to mitigate pollutant levels to ensure smooth urban living. To achieve this, installing filters on industrial chimneys, expanding natural gas infrastructure, and promoting the use of natural gas in non-infrastructure areas is essential. Should coal be employed for heating, selecting high-quality, low-soot Siberian coals with high energy content is advisable. Enhancing the city's green areas and parks, as well as expanding afforestation initiatives, holds merit. Efforts to curtail vehicular numbers, encourage public transportation, and prioritize carbon emiss…

type: item
description: With the help of information technologies, which are developing day by day, it has become easier to perform agricultural analyzes. Positional analyses can be performed with the help of Geographical Information Systems by gathering Climate, Soil, Topography and İrrigation data related to Agriculture. These analyses enables to generate analyses for agricultural investment maps, areas of agricultural conformity, plant pattern determination, etc. The purpose of this study is to prepare "Product Based Agricultural Risk Analysis Maps". Climate, Soil, Topography and Irrigation data, which are important in the growing of agricultural products are collected, severity and prospects for risk analysis are determined separately and risk values are established for each risk factor. The total risk value was calculated by prioritizing risk factors using the Analytical Hierarchy Process (AHP), one of the multi-criteria decision-making methods. Thanks to AHP, a methodology for calculating scenario-based risk values has been developed taking into account different probabilities. With the developed model, risk maps were created for climate, soil, topography and water constraints. The total risk map was obtained by combining the risk maps created with AHP. In this study, a model was established by taking the Peach and Fig product of Manisa and as a result of the model, Total Risk values were divided into classes such as "High Risk Areas", "Medium Risk Areas", "Low Risk Areas" and "Strictly Not Recommended Areas" according to the scores they received positional.

Assessing hydrological modeling approaches: a review of the soil conservation service curve number and the soil and water assessment tool
type: item
description: This article reviews two hydrological modeling tools, the Soil Conservation Service Curve Number (SCS-CN) model and the Soil and Water Assessment Tool (SWAT), and the Analytic Hierarchy Process (AHP) method used for estimating surface runoff and evaluating the impacts of land use changes on watershed responses. The SCS-CN model has been widely used for estimating surface runoff from rainfall, and its integration with GIS and remote sensing has improved its accuracy and precision. The SWAT model has also been effective in assessing the impact of land cover and land use changes on hydrologic response. The AHP method has been used to suggest the best locations for rainfall water harvesting in arid regions. However, these models also have limitations that should be considered when applying them to different watersheds. Proper calibration and validation of the models' input parameters are crucial to ensure accurate results, and the models' performance can be affected by uncertainties in the input data and model parameterization. Despite these limitations, these tools remain useful for evaluating surface runoff and its impact on water resource management, flood control, erosion prevention, and sustainable land and water management practices. In conclusion, the SCS-CN model, SWAT model, and AHP method are important approaches to evaluate surface runoff and its impacts, but their limitations and suitability for different watersheds should be carefully considered.

description: In this study spatial assessment of forest cover in Azad Kashmir was carried out. The study is based on secondary data. Satellite imageries of the past 20 years having temporal extent of five years were utilized for assessment of changes in vegetation covers. Supervised image classification and Normalized Difference Vegetation Index (NDVI) techniques were used to achieve objective of the study. The results indicated that forest cover is declining leading to different environmental problems. Increase in population acted as booster for the factors such as deforestation, conversion of forest land into agriculture and built-up land. These anthropogenic activities put pressure on the forest of the study region. After 2005 disastrous earthquake, rapid development of built-up environment was the leading factor behind clearing of forest. It was found from the analysis that forest cover has significantly declined in the last two decades and affected ecosystem services. Location specific management strategies are highly recommended to reduce the rapid decline in forest cover. Strategy must also consider the population growth and traditional forest conservation strategies. Alongside, keeping in view the agricultural activities and infrastructural development in the dense forest cover areas are also recommended.

Spatio-temporal analysis and trend prediction of land cover changes using markov chain model in Islamabad, Pakistan
type: item
description: Rapid urbanization is changing the landscapes of urban areas and affecting the quality of life and environment. One of the most dynamic components of urban environment is land cover, which have been changing remarkably since after the industrial revolution at various scales and population growth. Frequent monitoring and land cover change detection provides a better understanding of functions and health of urban environment. Remote sensing and Geographical Information System (GIS) are advanced techniques to visualize these dynamics in the digital map. Therefore, this study aims to analyze the existing spatial extent of different land cover classes and predict the future trend in Islamabad; Capital city of Pakistan, by applying Cellular Automata (CA)-Markov model. For this aim, three consecutive-year Landsat imagery (i.e. 200, 2010, 2020) were classified using the Maximum Likelihood Classifier. From the classification, three LULC maps with four class (Barren Land, Vegetation, Water Body, built up were generated, and then change-detection analysis was executed. Using remote sensing data, we simulated Spatio-temporal dynamics of land use and land cover changes Simulation results reveal that the landscape of Islamabad city has changed considerably during the study period and the change trend is predicted to continue into 2030. The study observed a significant increase in built-up area from 2000 (9.53%) to 2020 (28.2%), followed by an increase in the cover of bare ground. On the contrary, vegetation cover declined drastically 2000 (28.61%) to 2020 (25.08%). Rapid population growth triggered by rural urban migration coupled with hasty socio-economic development post democracy are the main drivers of these changes. Under the business as usual scenario, prediction analysis for the year 2025 and 2030 show that built up area will consume almost all of the city area (47.04%) to (57.25%) with vegetation significantly reduced to patches making up only about (17.23%) to (14.4%) of…

Heat maps of U-Th enrichments in open source coded geographical information systems (GIS); Arıklı (Çanakkale, Turkey) district
type: item
description: Uranium (U) and Thorium (Th) are both strategically important elements in the world. For this reason, it is exceedingly significant to explore for these elements, which are enriched in many geological environments. U-Th enrichments in Turkey were usually discovered in the Western Anatolian geography. U-Th anomalies were still observed in the Arıklı region in the south of Çanakkale. Remote sensing (RS) and geographic information systems (GIS) are platforms for the map-based evaluation of geological structures. In this study, RS and GIS were utilized in the QGIS program to carry out the geochemical data obtained in the field more understandable. GIS and remote sensing methods have been widely used to analyse the formation, origins, and processes of geochemical characters in ore deposits. U-Th values, which show high values in the fault zones in the Arıklı region, are immediately related to the CaO values. As in many geological studies, remote sensing and GIS studies suggest the opportunity to check out field data with a significant quality in the exploration of ore deposits.

Geochemical heat maps in complex geological structures via using QGIS: Maden (Elazığ) district
type: item
description: Geochemical analysis results are one of the most significant indicators that reveal the characteristics of the geological structures in a region. In particular, the differences in the composition of complex geological structures can be evident in field and Geographic Information Systems (GIS) studies. Turkey includes a character consisting of quite complex features with its geological structure. The Maden (Elazığ) complex has also attracted the attention of many researchers with its complex structure. The Maden Complex also contains basalts, basaltic andesite, andesite, dacite, diabase, and pyroclastic rocks, which are intercalated and lateral-vertical transitive with all these sedimentary successions. Mapping and lithological differentiation of the Maden Complex, which has a very complex structure, is difficult. The geochemical analysis of the samples taken from the field was transferred to the GIS environment with their coordinates. Thematic maps are created to make the geological interpretations in this region cleaner and the field data more predictable. These maps also allow the correlation of major oxides and trace elements. In this study, the geochemical data obtained in the Maden Complex were analyzed in the QGIS program. The geochemistry of the region has been made more understandable and interpreted with heat maps. The diversification of thematic maps, which gives a new perspective to geochemical data, will provide more support to geological studies.

A geographical information systems (GIS) perspective on European green deal and sustainability
type: item
description: The European Union (EU), known for its sensitivity to environmental and social sustainability issues, especially on topics such as combating climate change, reducing greenhouse gas emissions, and using renewable energy since the 1990s, took these sensitivities one step further in November 2019. In November 2019, it took these sensitivities one step further and presented a package of initiatives, a commitment by the Union to take firm and ambitious steps in environmental and sustainability issues: The European Green Deal. The Memorandum aroused significant repercussions for all state, international organisations and private sector players that have economic, political and geographical connections with the EU, because the Consensus, which consists of the standards set by the EU for its member states, also has the potential to affect the relations of EU countries with third parties. This situation has revealed the necessity of a good understanding of the Agreement by everyone, given the wide commercial and diplomatic ties of the EU. In the geographic data infrastructure designed within the scope of this study, a total of 26 intermediate criteria grouped in 5 main criteria were used. Within the scope of the study, we aim to test the analysis to be made with the availability of quantitative data and topographic data by the European Green Reconciliation. By making use of these data used in the continuation of our study, expert opinions, surveys, etc. can be weighted with AHP or TOPSIS method, and positions, companies, etc. that are important for the Green Reconciliation can be determined.

Automatic construction of a knowledge base for transport networks
type: item
description: Abundant spatial transport data is accessible from governmental institutions or internet sources contributed from all over the world. This kind of data obtained from various sources exists in different structures and prevents interoperability. The aim of the research, in this paper, is to develop an ontology compatible with specifications of transport networks of Infrastructure for Spatial Information in the European Community (INSPIRE) and to obtain a knowledge base of transportation data from non-semantic data sources automatically. In the first stage, ontological classes and relations in the transport network are explained. Then, defining algorithms in three main phases, non-semantic spatial data is transformed into the ontological structure. Some ontological queries are implemented to retrieve information from a knowledge base that is produced because of the transformation algorithms. As a result of the study, the transportation datasets in the relational database have been successfully converted into a semantic data format. The functionality of the obtained knowledge base was validated with queries that allow semantic reasoning.

type: item
description: It is seen that there is a parallelism between the economic power of the countries and the development of the logistics sector of their sustainable competition. According to the free market economy in the Keynesian economic system, the logistics sector has an important function. With the globalization of the world, the logistics sector gains importance and this makes railway logistics gain importance. The development of railways allows the development of the economy. Since it positively affects the cost-benefit analysis of public institutions and organizations and the private sector, the railway route should be chosen in the most appropriate way. In the determination of the route Geographic Information System (GIS) applications are used with the developing technology in recent years. Geographic Information Systems applications, on the other hand, play a major role in collecting data analytically, obtaining results and using the results thanks to computer technologies and software systems. The Analytical Hierarchy Process (AHP) method, which is used together with Geographic Information System (GIS) applications, makes it possible to provide the most appropriate and maximum benefit in line with certain parameters by comparing the alternatives in the decision-making process in the most appropriate way. These parameters considered include slope, aspect, stream, building, small water flow and transportation. Taking these parameters into account, the conditions affecting the railway line were evaluated using the AHP method.
