Exploring geomasking methods for geoprivacy: a pilot study in an environment with built features.

This study discusses the ethical use of geographical information systems (GIS) data with a focus on geomasking for upholding locational privacy. As part of a pilot study in Jeddah City, Saudi Arabia, we used open-source geomasking methods to ensure geoprivacy while examining built environment features that determine the quality of life among individuals with type-II diabetes. We employed the open-source algorithms Maskmy.XYZ and NRand-k for geomasking 329 data points. The results showed no differences between global and city-level spatial patterns, but significant variations were observed with respect to local patterns. These findings indicate the promising potential of the chosen geomasking technologies with respect to ensuring locational privacy but it was noted that further improvements are needed. We recommend developing enhanced algorithms and conducting additional studies to minimize any negative impact of geomasking in spatial analysis with the overall aim of achieving a better understanding of ethical considerations in GIS sciences. In conclusion, application of geomasking is straightforward and can lead to enhanced use for privacy protection in geospatial data analysis.

Spatio‐temporal availability of renewable energy sources for Western Paraná

AbstractThe hydroelectric crisis is fomenting studies that seek the decentralization of electric energy generation in Brazil. Due to the climatic dependence on alternative sources, knowing their intermittent behavior is the best way to ensure supply. This article presents an analysis of energy complementarity based on the occurrences of climate variables with precipitation for hydroelectric power, irradiation for photovoltaic, and wind speed for wind power. We aimed to analyze and spatialize the availability of renewable energy sources in western Paraná through historical series (2011 to 2020), statistical analysis (monthly and seasonal), and the use of Geographic Information System (GIS). Daily data records were made available by the Paraná Meteorological Institute (SIMEPAR), referring to eight weather stations throughout the mesoregion. The results identified spatial complementarity for the mesoregion West Paraná. Cascavel city stood out for temporal complementarity, recording the highest values for precipitation in spring and wind speed in winter. In addition, irradiation data excelled in summer for the city of Santa Helena when compared to the other municipalities considered.

Transformative Role of Remote Sensing in Advancing Horticulture: Optimizing Sustainability, Efficiency and Resilience

The field of horticulture, vital for addressing global challenges like food security and sustainable agriculture, has been revolutionized by remote sensing technology. This comprehensive review explores the transformative impact of remote sensing on horticulture, emphasizing its role in optimizing resource utilization, promoting environmental sustainability, and mitigating the effects of climate change. Remote sensing, encompassing a range of sensors, satellites, and data analysis techniques, enables the collection of critical information from a distance, providing insights into crop health, soil conditions, water availability, and more. Precision agriculture, including the use of GPS and GIS, is integrated with remote sensing to enhance agricultural efficiency while minimizing environmental impacts. Site-Specific Crop Management (SSCM) is highlighted as a key component of precision agriculture, enabled by geospatial technologies, including remote sensing. It discusses how remote sensing systems, with their multispectral and multi-temporal capabilities, support various horticultural applications such as crop yield estimation, abiotic and biotic stress management, crop classification, canopy measurement, crop area estimation, and even crop insurance validation. The use of Geographic Information Systems (GIS) and the Global Positioning System (GPS) in tandem with remote sensing is explored in the context of spatial analysis, mapping, and precise navigation.

Development of Highway Information System in GIS Environment Himachal Pradesh

Managing information to assist more efficient decision making is currently in high demand for transportation organizations, from engineering at the micro level to statewide planning and management at the macro level. Furthermore, data sharing and cooperation among several government agencies at all levels are required to address the complex environmental and economic development issues that face society today. In the past, the majority of transportation agencies and government sectors frequently used information systems and database development for particular applications. The use of geographic information systems (GIS) outside of the transportation sector has been quite effective. Since GIS in transportation (GIS-T) has been used in numerous transportation projects to detect transportation-related problems, it (GIS-T) offers thorough and timely information for sound decision-making. Using geographic information systems for storage is effective. Geographic data from the real world is retrieved, modified, and displayed for transportation systems. In many nations throughout the world, GIS has been utilized as an effective development platform for information systems for the management of pavement maintenance. Road widening or upgrading, maintenance management, evaluation, geometric design and improvement, and other operations related to road transport can all be managed with the help of a GIS-based Highway Information System (HIS). In the current dissertation, GIS was used to create a highway information system. Many road factors including topography characteristics, distresses, traffic data, highway amenities, and pavement data were gathered.

GIS analyses of land consolidation in case of the highly fragmentated of parcels

Abstract Spatial planning and arrangement work of rural areas is constantly being renovated to improve the living conditions, land distribution and to facilitate work in this area by reducing the costs of transport. The most effective solution is consolidation and exchange of land, which is a difficult and time-consuming process. However, it significantly facilitates everyday functioning of the inhabitants of the village. It assumes reduction of plots of land belonging to the farm by increasing the area of other plots, regulating the shape, ensuring access to the public road and shortening the distances of individual farmland to their habitats (built on site). The purpose of this work was the analysis of land consolidation and exchange process for the village of Lukowa with the use of Geographical Information System (GIS) tools. Primary aim set at the beginning of the project is to compare the state before the land consolidation and the design of the parcel posting after consolidation. QGIS free software has been used to solve this problem. Two basic activities were carried out to compare the distance between built-up land and the remaining farmland. For this purpose, two analyses were performed: network analyses assuming the calculation of distance along the shape of roads and linear analyses determining the shortest distances between plots on a straight line. The work considers the real land distribution, the calculation of which is a time-consuming task. Many factors must be considered to accurately determine the correct distances. It is shown what difficulties and problems occur during the collection of data for analysis, with the correct indication of habitats and indicating the road network or aggregation of adjacent plots of one owner.

Road modelling for infrastructure management – the efficient use of geographic information systems

The construction sector is undergoing a digital transition. Local authorities have adopted geographic information systems (GISs) to plan their territories and structure their services, such as transport. Simultaneously, building information modelling (BIM) has demonstrated its advantages during the design and construction phases of structures. An infrastructure project can rely on these two technologies to plan its implementation (GIS), to complete its design and construction (BIM), or to manage associated services, such as mobility (GIS). However, road maintenance, an important part of the infrastructure’s life cycle, is not yet covered by these technologies. Road maintenance necessitates a comprehensive view of the infrastructure and its interactions with other real-world objects (e.g. vegetation, technical networks, or vehicles). Moreover, road managers are the local authorities that already use GISs. For these reasons, a GIS is suitable for fulfilling road maintenance requirements. This study presents a spatial framework (GIS) developed for road management. Applying it to a specific case study provides insights on the organisation of the spatial road framework which can be adapted to the infrastructure’s environment management. The spatial dimension must allow for the representation of the road and its components, including pavements and their dependencies. The structural dimension must be detailed to describe the layers, their formulations, and their thicknesses. The condition of the road must be described concisely so that the managers can plan maintenance.

The Role of Geographic Information System in Environmental Planning and Management in Oman

The use of Geographic Information Systems (GIS) has grown to cover various disciplines. The ability to use big data and geoprocessing tools allowed many sectors to use spatial data analysis and modeling for more effective decision-making and increased productivity. The use of GIS has become even more vital in the field of environmental planning and management, where incorporating environmental information contributes significantly to sustainable development. In addition, the ability to use spatial modeling at small-scale local or large-scale regional levels will broaden the knowledge of the direct and indirect impacts of development projects on the environment. This paper assesses the role played by GIS in Oman for generating information to gain insight into the many environmental challenges faced by the country toward more sustainable development. It provides an overview of what has been achieved, the approaches taken, and the way forward.

Analysis of the vegetation fragments connectivity

The habitat fragmentation is one of the most cited causes of species extinction and loss of biological diversity and it is defined as the process by a continuous area is reduced in size and divided into two or more fragments separated by an environment or matrix, different from the original. The analysis of landscape fragmentation is done through land use mapping, where it is possible to identify different spots and determine the degree of fragmentation or connectivity. This work aims to analyze the connectivity of the landscape fragments present in the Tietê-Jacaré Hydrographic Basin - SP, through the application of the metric indices of Connectivity and Fragmentation, with the purpose of evaluating the dynamic and temporal process in 2007 and 2017, through the use of Geographic Information Systems (GIS). Considering the interval of 10 years, there was an expansion of agricultural activities with an increase of 24,507.53ha of cultivated areas and a vegetation loss of 32,149ha. It was also evidenced the decrease in the number of fragments, as well as the increase in the average size of the fragments, derived from the growth of the agricultural matrix with consequent reduction of the fragment’s diversification. The vegetation configuration of the region has undergone few structural changes, the main connections are related to the end of each sub-basin and consequently the hydrographic basin as a whole. The fragmentation indexes, when expressing the state of configuration of the landscapes, were presented as important tools in the diagnosis aimed at the conservation of ecosystems. These indices allowed the comparison not only of natural fragments but of all classes of land use and land cover, which is essential in regional planning.

Task-shifting for point-of-care cervical cancer prevention in low- and middle-income countries: a case study from Uganda.

Cervical cancer remains the leading cause of female cancer deaths in sub-Saharan Africa. This is despite cervical cancer being both preventable and curable if detected early and treated adequately. This paper reports on a series of action-research 'cycles' designed to progressively integrate a comprehensive, task-shifted, point-of-care, prevention program in a community-based public health facility in Uganda. The work has been undertaken through a UK-Ugandan Health Partnership coordinated by Knowledge for Change, a UK-registered Charity. The intervention demonstrates the effectiveness of task-shifting responsibility to Community Health Workers combined with the use of Geographic Information Systems to strategically guide health awareness-raising and the deployment of medical devices supporting respectful and sustainable point-of-care screen-and-treat services. The integration of this with public human immunodeficiency virus services demonstrates the ability to engage hard-to-reach 'key populations' at greatest risk of cervical cancer. The findings also demonstrate the impact of external influences including the Results Based Financing approach, adopted by many foreign Non-Governmental Organizations. The model presents opportunities for policy transfer to other areas of health promotion and prevention with important lessons for international Health partnership engagement. The paper concludes by outlining plans for a subsequent action-research cycle embracing and evaluating the potential of Artificial Intelligence to enhance service efficacy.

Impact of the COVID-19 Pandemic on Tourism: A Clustering Approach for the Spanish Tourism Analysis

Since the middle of the last century, the Spanish tourism sector has experienced significant growth, which was interrupted by the effects of the COVID-19 pandemic. This situation had a considerable impact on Spain, as the country is a leading world tourism destination and relies heavily on this sector in its economy, making it vulnerable when demand for tourism services declines. The tourism model in Spain is not homogeneous, and the Mediterranean coastal regions and island areas are highly dependent on tourism as a main source of economic income and were particularly affected by the consequences of the pandemic. This study analyzes the impact of the pandemic on the tourism sector in each Spanish autonomous community, focusing on tourism demand through the use of Geographic Information Systems (GIS). The results reveal the disparity and vulnerability of Spanish regions to the tourism crisis. The most tourist-dependent areas dependent on international tourism have experienced a decline due to restrictions and a fall in demand. On the other hand, rural regions that depend mainly on national tourism have suffered fewer effects.

Identification of river basins within northwestern slope of Crimean Mountains using various digital elevation models (ASTER GDEM, ALOS World 3D, Copernicus DEM, and SRTM DEM)

Since the end of the 20th century, the use of geographic information systems and digital elevation models has reduced the time required for and improved the quality of morphometric analysis of the relief within river basins. However, researchers are constantly faced with the problem of choosing the most accurate and suitable digital terrain model for their task. Many global, regional, and local digital elevation models are available. In this study, we comparatively analyzed the accuracy of the ASTER GDEM, ALOS World 3D, Copernicus DEM, and SRTM DEM spatial datasets for the purpose of catchment basin modeling for the river basins of the northwestern slope of the Crimean Mountains (Zapadnyy Bulganak, Alma, Kacha, Belbek, and Chernaya Rivers) as an example. For each river basin, we calculated the systematic, root mean square, mean absolute, standard root mean square (Bessel’s correction), and centered mean absolute errors by comparing ASTER GDEM, ALOS World 3D, Copernicus DEM, and SRTM DEM data with a 1:100,000 topographic map within the considered river basins. We found the smallest error values for the Copernicus DEM and ALOS World 3D datasets; furthermore, we used the Copernicus DEM dataset to model the river basins and sub-basins of the northwestern slope of the Crimean Mountains. As a result, we identified these river basins and sub-basins for the Zapadnyy Bulganak, Alma, Kacha, Belbek, and Chernaya Rivers, which are represented by stream basins, valleys, gullies, and ravine systems.

Utilization Of Geographic Information Systems (SIG) In Mapping Rivers As Alternative Transportation Routes In Jakarta

Abstract—Public transportation is an important means of transportation for people's lives. The importance of transportation is reflected in the increasing need for transportation services to move people and goods from one place to another. For this reason, there needs to be a way to be able to overcome congestion that occurs due to heavy traffic activities that occur on land. One way is to use the river as an alternative means of transportation. River currents can be used as a means of transportation by using watercraft such as amphibious buses. Therefore, river mapping studies are needed to study optimal routes so as to integrate amphibious bus transportation routes. The way that can be done is by maximizing the use of geographic information systems (GIS) for making mapping of the river path, so it is hoped that with the existence of water transportation routes, it can be a good solution to reduce the level of congestion that occurs in DKI Jakarta.

A novel artificial neural network methodology to produce high-resolution bioclimatic maps using Earth Observation data: A case study for Cyprus

The aim of this research is to propose a novel methodology that exploits Earth Observation (EO) data to accurately produce high-resolution bioclimatic maps at large spatiotemporal scales. This method directly links EO products (i.e., land surface temperature - LST and Normalized Difference Vegetation Index - NDVI) to air temperature (Tair) and such thermal indices as the Universal Thermal Climate Index (UTCI), and the Physiologically Equivalent Temperature (PET) to produce large-scale high-quality bioclimatic maps at a spatial resolution of 100 m. The proposed methodology is based on Artificial Neural Networks (ANNs), and the bioclimatic maps are developed with the use of Geographical Information Systems. High-resolution LST maps are produced from the spatial downscaling of EO images and the application of the methodology in the case of the island of Cyprus highlights the ability of EO parameters to estimate accurately Tair as well as the above mentioned thermal indices. The results are validated for different conditions and the overall Mean Absolute Error for each case ranges from 1.9 °C for Tair to 2.8 °C for PET and UTCI. The trained ANNs could be used in near real-time for estimating the spatial distribution of outdoor thermal conditions and for assessing the relationship between human health and the outdoor thermal environment. On the basis of the developed bioclimatic maps, high-risk areas were identified. Furthermore, the study examines the relationship between land cover and Tair, UTCI, and PET, and the results provide evidence of the suitability of the method to monitor the dynamics of the urban environment and the effectiveness of urban nature-based solutions. Studies on bioclimate analysis monitor thermal environment, raise awareness and enhance the capacity of national public health systems to respond to thermally-induced health risks.

Analysis of changes in mangrove land cover on the north coast of Aceh Besar

The use of Geographic Information Systems (GIS) to generate digital data that provides information on the characteristics of an area and describes changes in land cover that can be used in a more effective and efficient sustainable manner. This study aims to analyze the mangrove land cover of the north coast of Aceh Besar over the last three decades, namely 2000, 2010, and 2020 in the Baitussalam sub-district, Mesjid Raya sub-district and Seulimeum sub-district. The research was conducted from June 2022 to September 2022 at the GIS Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University. The research was conducted using a Geographic Information System (GIS) that utilizes high-resolution satellite imagery from Google Earth Pro. Mangrove land was digitized visually on screen, then data processing was carried out, and spatially analyzed. The results of the analysis of changes in mangrove land cover in the research area show that the Baitussalam and Mesjid Raya sub-districts had a decreasing trend of mangove land between 2000 and 2010 and subsequently there was an increase in mangrove land cover from 2010 to 2020. Meanwhile, Seulimeum sub-district experienced a decreasing trend of land cover in 2000 until 2020. The decline in the trend of mangroves in various places is caused by the growth of the population using mangrove land as residential area. While the increase in mangove land cover was due to the success of reforestation and pond land conversion. The results conclude that the mangrove land cover on the north coast of Aceh Besar is relatively stable with an increasing trend of growth.Keywords:Land coverMangroveHigh resolution googleHistorical imageryGoogle earth proDigitize

Climate change vulnerability hotspots in Costa Rica: constructing a sub-national index

For policies and programs aiming at reducing climate risk, it is important to obtain vulnerability information at the sub-national level to identify hotspots. For the case of Costa Rica, no sub-national climate vulnerability index exists to date. To fill this gap, we constructed a climate vulnerability index at the canton level. We ground our work in the conceptual framework that vulnerability is a function of exposure, sensitivity, and adaptive capacity. Making extensive use of geographic information systems and publicly available data, we constructed 13 spatial layers to reflect the multi-dimensionality of vulnerability. Layers reflect for example, changes in climatic extremes, flood risk, vegetation cover, access to infrastructure (road density) and health services (distance to hospitals), as well as various socioeconomic (wealth level, employment rates, remittances, literacy rate) and demographic (infant mortality) characteristics. Following normalization, we constructed an inverse variance weighted index of canton-level climate vulnerability. We confirmed the validity of our climate vulnerability index through correlation with disaster damage data. We find the strongest climate vulnerability not only in the rural, agricultural producing border cantons (Los Chiles, Matina, Talamanca, Buenos Aires), but also for a few central urban cantons (Tibas, San Jose). Projects and interventions in these hot spot cantons may reduce sensitivity through strengthening hydrological infrastructure and economic development, while adaptive capacity may be improved through addressing barriers of remittance transfer, and via public health programs.
