Full textAbstract:
The frequency and intensity of flood disasters have become serious issues in the national development process of Nigeria as flood disasters have caused serious environmental damages, loss of human lives and other heavy economic losses; putting the issue of disaster reduction and risk management higher on the policy agenda of affected governments, multilateral agencies and NGOs. The starting point of concrete flood disaster mitigation efforts is to identify the areas with higher risk levels and fashion out appropriate preventive and response mechanisms. This research paper explored the potentials of Geographic Information System (GIS) in data capture, processing and analysis in identifying flood-prone areas for the purpose of planning for disaster mitigation and preparedness, using Benin-Owena river basin of Nigeria as a unit of analysis. The data used in this study were obtained from FORMECU and were entered and use to develop a flood risk information system. Analysis and capability of the developed system was illustrated and shown graphically. The research showed that over one thousand settlements harbouring over ten million people located in the study area are at grave risk of flooding. Key words: Flood, Risk, Vulnerability, Geographical Information System (GIS), River -Basin

Malaria is one of the tropical diseases popularly known all over Africa. It is caused by the female Anopheles mosquitoes which transmit Plasmodium falciparum into human blood and result in high fever or sudden death. Based on this study, people from the less developed region have poor hygiene and sanitation that contributed to the spread of the vector causing malaria. In this study, geospatial techniques were applied to collect the samples, about 125 samples were collected. The GPS capture was employed using the satellite image to georeference the area study. The data obtained are of four types; the National Health Management Information System (NHMIS, National Malaria Elimination Programme; Malaria Health Product-Daily Consumption Register, Minjibir General Hospital (Federal Ministry of Health), Sample Field Survey (Questionnaire) and Kano State Contributory Healthcare Management Agency (KSCHMA). The results indicated that over 26.4% of children are vulnerable to malaria, 24.8% of infants and 24% of adults. The overall analysis of the 5 villages including minjibir Gari surveyed have 84% of people tested positive with plasmodium falciparum in their blood and a few over 16% were tested with a negative reaction.

This paper demonstrates that the advent of GIS has led to situations in the processes of scientific investigation that are indicative of a paradigm shift in both research focus and efforts in the environmental and social sciences, delivery of health facilities and services, and in numerous areas of urban and regional planning. It is argued that the deep involvement of Geographic Information Science and Technology (GIS&T) in various national development activities has also led to a greater understanding of socio-political systems. It is demonstrated that GIS&T possesses the potentials to change how we abstract the world, how we reason about the world, and also how we organize and communicate with one another, thus opening new research frontiers. Furthermore, it is argued that as it is already changing the way people work in advanced countries, it could also change the way we work and interact in Nigeria. While recognizing the yawning gaps in the current level of awareness and usage of GIScience and Technologies in the Nigerian development process, some modest efforts of research addressing the needs of the technology were discussed. Of course, GIS offers geography as a science to develop a new microscope with which to view the world and possibly revive its glory as of the king or queen of the sciences.

Abstract Flood-induced fatalities are among the more poorly reported effects of flood disasters in many developing countries because of poor data inventory and management. Specific objectives of this study are to assess the spatial and temporal variations in flood fatalities in Nigeria, the most populous country in Africa. The study explored available datasets from the National (Nigerian) Meteorological and Emergency Management Agencies as well as those from the Dartmouth Flood Observatory (DFO) at the University of Colorado Boulder and complemented those with scattered reports from Nigerian newspapers to achieve the stated objectives. Using a mix of statistical and geographical information analysis approaches, the study showed that most of Nigeria is vulnerable to flood, given the nature of the dominant climate that often results in “medium” to “high” rainfall intensity (i.e., rainfall = 38.1–50.1 mm or > 50.1 mm in 24 h, respectively), inadequate settlement planning/land-use and land-cover management, and dam failure. Analysis of the frequency of the flood–fatality relationship indicates an increase in flood fatalities by 4.7% relative to flood cases between 1985 and 2017. The study complemented the results with information from newspapers and some other non-peer-reviewed documents (especially reports from relevant agencies) and revealed the need for a better flood information management system in the country, especially since the national database and DFO records were not the same. The study concluded that flood fatalities are on the increase but are poorly reported. It thus recommends improved information systems for flood and other disasters and their fatalities in the country. Significance Statement The purpose of this study is to reveal the state of information on flood disasters in a typical sub-Saharan African country. This is important because information about the distribution and trend of fatalities associated with flood disasters is required for sustainable mitigation planning globally. Our results provide a guide to understanding the distribution and associated factors of flood disasters as well as the contributions of informal (newspaper) sources to the inventory of relevant records.

Full textAbstract:
This study investigated the characterization of vehicular noise pollution and established health standards in Port Harcourt metropolis, Rivers State, Nigeria. There were four types of data collected for this study: vehicular noise data were collected across the junctions and roundabouts using the Noise Level Meter (NLM); vehicular traffic data were generated by observation and counting vehicles that passed each junction and roundabout; vehicular traffic map was developed using the Global Positioning System (GPS) device analyzed in the Geographic Information System (GIS) environment and vehicular noise levels were matched with national and international standards respectively. The result indicated that Port Harcourt metropolis has exceeded both the national and international vehicular traffic noise standard of 70dB which has triggered physiological and psychological health challenges to residential areas and the general road users as well as the public. This study recommended that there should be improved road network across the city, especially the southern and western segments in order to ameliorate vehicular noise pollution. Effective road-safety management framework should be developed and implemented. Finally, state and national laws on noise pollution offenders should be implemented in order to reduce vehicular noise pollution and provide a safe as well as livable environment for Port Harcourt city dwellers.

Full textAbstract:
Global Navigational Satellite System (GNSS) over the past and present time has shown a great potential in the retrieval of the distribution of water vapour in the atmosphere. Taking the advantage of the effect of the atmosphere on GNSS signal as they travel from the constellation of satellite to ground-based GNSS receivers such that information (water vapour content) about the atmosphere (mostly from the troposphere) can be derived is referred to as GNSS meteorology. This paper presents the spatiotemporal variability of Precipitable Water Vapour (PWV) retrieved from ground–based Global Navigation Satellite System (GNSS) stations over Nigeria for the years 2012 to 2013. In this paper, the GNSS data were processed using GAMIT (ver. 10.70). The GNSS PWV were grouped into daily and monthly averages; the variability of the daily and monthly GNSS PWV were compared and validated with the daily and monthly PWV from National Centre for Environmental Prediction (NCEP) and monthly Rainfall data for the study years respectively. The results revealed that the spatiotemporal variability of PWV across Nigeria is a function of geographic location and seasons. The result shows that there is temporal correlation between GNSS PWV, NCEP PWV and rainfall events. The research also affirms that GNSS PWV could be used to improve weather forecasting/monitoring as well as climate monitoring.

MATTER: International Journal of Science and Technology 8, no. 2 (July 19, 2022): 18–33. http://dx.doi.org/10.20319/mijst.2022.82.1833.
Full textAbstract:
Renewable energy has been highlighted not only as a means of satisfying the energy needs of Nigerians but also as a tool for the country's growth, thereby improving the income of the citizens who have more energy to work with, serving as the energy source for domestic and office use, in addition to reducing the carbon footprint from the conventional fossil fuels. From data obtained from the Photovoltaic Geographic Information System (PVGIS), the solar electricity potential at some selected cities in Southern Nigeria that ranges from 4.5 to 6.5 kWh/m2 has been presented as a tool, which when properly harnessed, can be used to mitigate avoidable energy-related “national disasters” such as unemployment and youth-restiveness, thereby accelerating Nigeria’s development. There is the urgent need to revise and effectively implement helpful laws and policies that support the addition of renewable energy sources for electricity generation. Lack of a coherent legal framework with incentives for the utilization of renewable energy is among the key factors causing poor utilization of renewable energy in Nigeria. Governmental and stakeholder collaboration is highly necessary for developing countries to robustly track renewable electricity adoption via laws aimed at boosting its adoption.

Full textAbstract:
The study demonstrated that spatial analysis with relevant socio-economic sources and physical parameter from different sources can be evaluated for the filling station sites planning. This has demonstrated the importance of Geographic Information System (GIS) application in predicting and determining of site criteria for filling stations facilities development, most especially in areas where there is land uses competition which requires consumer accessibility, sustainability, environmental safety, environmentally sensitive development solutions, etc. A stratified sampling technique was used to select the sample size and administration of the questionnaire. The data collected was analyzed using descriptive statistics such as frequency distribution, bar chart, pie chart and percentage and maps showing the sampled existing filling stations in the study area. The result shows the distribution of filling stations located across the study area. This study shows that GIS and multi-criteria analysis are essential tools to assist in correct siting to national planners and decision-makers in deciding the most appropriate filling stations location pattern to apply in Minna and its environs.
Keywords: GIS, filling stations, spatial distribution, location, distance.

<p><em>African countries in recent times have witnessed an unprecedented level of insecurity. This has made national security threat to be a major issue for the government and has prompted huge allocation of the national budget to security. The objective of this paper is to mark out crime hotspot areas in the central area of Akure metropolis; and examine the rate at which crimes are committed, the surveillance method used and its effectiveness. The research made use of Google Earth imagery and Geographical Information System (GIS) technology to delineate crime hotspots in Akure. A 100m buffer was created around the identified crime hotspots to select houses that are susceptible to the impacts of crime activities in the study area. A structured questionnaire was also used to elicit information on crime, surveillance method, and effect of crime on the people and level of occurrence in the city among others. Findings identified six major crimes in eight hotspot areas; noise, loss of property and threat to life were some of the effects of hotspots on residents. The paper recommends construction/repair of roads in the core residential areas for effective surveillance of hotspots. The use of satellite images to combat crime in the city is also canvassed.</em><em></em></p>

Background The assessment of geographical heterogeneity of HIV among men who have sex with men (MSM) and people who inject drugs (PWID) can usefully inform targeted HIV prevention and care strategies. Objective We aimed to measure HIV seroprevalence and identify hotspots of HIV infection among MSM and PWID in Nigeria. Methods We included all MSM and PWID accessing HIV testing services across 7 prioritized states (Lagos, Nasarawa, Akwa Ibom, Cross Rivers, Rivers, Benue, and the Federal Capital Territory) in 3 geographic regions (North Central, South South, and South West) between October 1, 2016, and September 30, 2017. We extracted data from national testing registers, georeferenced all HIV test results aggregated at the local government area level, and calculated HIV seroprevalence. We calculated and compared HIV seroprevalence from our study to the 2014 integrated biological and behavioural surveillance survey and used global spatial autocorrelation and hotspot analysis to highlight patterns of HIV infection and identify areas of significant clustering of HIV cases. Results MSM and PWID had HIV seroprevalence rates of 12.14% (3209/26,423) and 11.88% (1126/9474), respectively. Global spatial autocorrelation Moran I statistics revealed a clustered distribution of HIV infection among MSM and PWID with a <5% and <1% likelihood that this clustered pattern could be due to chance, respectively. Significant clusters of HIV infection (Getis-Ord-Gi* statistics) confined to the North Central and South South regions were identified among MSM and PWID. Compared to the 2014 integrated biological and behavioural surveillance survey, our results suggest an increased HIV seroprevalence among PWID and a substantial decrease among MSM. Conclusions This study identified geographical areas to prioritize for control of HIV infection among MSM and PWID, thus demonstrating that geographical information system technology is a useful tool to inform public health planning for interventions targeting epidemic control of HIV infection.

Full textAbstract:
Big data technologies have intensified the need for Sustainable Data Governance (SDG). Significant empirical evidence from literature revealed that of the 2.7 zettabytes of data now in the digital universe, only 67% of organizations deployed data governance or data intelligence solutions, 76% of company executives consider information "mission-critical" or most important asset, while 46% including Nigeria had no formal governance strategy in place. Globally, significant relationships exist between SDG and Sustainable Information and Communication Technology (SICT). Data governance (DG) that is driven by SICT is agile, holistic, security-embedded, accurate, high-quality, sustainable, and on a real-time enterprise data pipeline, required in revamping any nation’s economy. Despite these global impacts of SDG in revamping the national economy, numerous investigations have shown that DG in Nigeria has remained relatively non-existent or unattended to because its approach is driven by IT that adopted rigid and fragmented processes that were carried out on a system by system basis, lacked a single version of the truth or one single reference for critical master data across geographies, business structure, and wider support of the organization. Poor sustainability of ICT in Nigeria also posed barriers that impede progress related to DG due to corrupt policies and practices, ignorance, and illiteracy that plagued SICT innovations in Nigeria. The authors adopted the Unified Theory of Acceptance and Use of Technology (UTAUT) as the conceptual framework for this study. UTAUT model claimed that users’ acceptance behavior towards technology is determined by users’ perceived benefits of using technology and the factors that drive users’ decision to use it. A narrative review methodology was adopted in this study to review significant information based on the study conceptual framework, and existing systems that enhance SDG in revamping Nigeria’s economy. Articles reviewed include peer-reviewed articles and other documentaries within the last 5 years, extracted from electronic databases, using keywords such as “ICT and SDG”, “SDG and national economic development”, “Trends for SDG”, etc. Results from this study revealed that better decision-making, analytics, and regulatory compliance to policies, laws, and guidelines on the adoption of ICT, coupled with good formulation and communication of same, are the major drivers of sustainable DG for revamping the national economy. The result of this study may increase understanding, minimize corrupt practices and encourage trust and regulatory compliance of ICT innovations, adoption, and sustainability that can positively impact SDG for revamping Nigeria’s economy.

Full textAbstract:
Data from national health information systems are essential for routinely tracking progress, programmatic decision-making and to improve quality of services. Understanding the data elements captured in patient registers which are building blocks of national HMIS indicators, enables us to standardize data collection and measurement of key indicators for tracking progress towards achieving maternal and newborn health goals. This analysis was done through a review of antenatal care (ANC), childbirth and postnatal care (PNC) registers from 21 countries across five geographic regions. Between July and October 2020, country-based maternal and newborn experts, implementing agencies, program managers, and ministry of health personnel were asked to share the registers in use. Both paper-based and electronic registers were obtained. Twenty ANC registers, eighteen childbirth and thirteen PNC were available and analyzed. Both longitudinal and cross-sectional ANC and PNC registers were obtained, while the childbirth registers included in the analysis were all cross-sectional. Fifty-five percent (11/20) ANC registers and 54% (7/13) PNC registers were longitudinal. In four countries, the registers were electronic, while the rest were paper-based (17 countries). Sub-analysis of registers from four countries (Ghana, Kenya, Nigeria, and Zambia) where the 2017/2018 and 2019/2020 registers were available showed that the latest versions included 21/27 (78%) of data elements that are critical in the computation of key maternal and newborn care indicators. This analysis highlights some areas in where there are data gaps in data on pregnancy and childbirth. Program managers and health workers should use data gathered routinely to monitor the performance of their national health system and to guide the continuous improvement of health care services for women and newborns. The findings can help to inform the standardization of pregnancy and childbirth registers, and provide information for other countries seeking to introduce indicators in their health systems.

Background: Spatial noise level mapping using a geographical information system (GIS) is essential for the visual colour representation of noise analysis, which is a necessity for strategic planning and mitigating measures. Methods: Extech noise meter (model 407750) was used for sound measurement and a GIS (inverse distance weighted) was used in 54 study locations for the spatial interpolation. The study was classified into five categories based on Nigeria’s WHO standard and National Environmental Standards and Regulations Enforcement Agency (NESREA). Results: For the LDAY (D),LEvening (E), LNight (N), and LDEN, all the locations exceeded the WHO standard while 94.4%, 90.7%, 83.3%, and 83.3% of the locations exceeded the NESREA standard. The LDay (D) ranged from the minimum value of 67.6 dB (A) at the Ijaw residential area to the maximum value of 93.0 dB (A) at Kwangila site (1) intersection. The LNight ranged from the minimum value of 63.3 dB (A) at Dogorawa residential area to the maximum value of 92.1 dB (A) at Kwangila site (1). The LDEN ranged from the minimum value of 73.1 dB (A) at Hanwa residential areas to the maximum value of 97.2 dB (A) at Kwangila site (1). The noise quality rating ranged from satisfactory to unallowed noise quality grading. The selected intersections and residential areas with light commercial activities had the highest and lowest noise levels, respectively. Conclusion: Efficient maintenance of silencers, planting trees with dense foliage, and strategic planning would be necessary panacea in curbing excessive noise.

This study aims to investigate geo-referenced vehicular noise pollution in Port Harcourt metropolis of Rivers State, Nigeria. Three types of data were gathered for this study. Data from vehicular traffic noise were measured in decibel (dB) using Noise Dosimeter (ND); data from vehicular traffic counts were carried out by observing and counting traffic flow at junctions and roundabouts as well as vehicular traffic noise location map was established by using Global Positioning System (GPS) instrument processed in the Geographic Information System (GIS) environment. The findings indicated that in the northern segment, Igwurita (99.5 dB) and New road roundabout (96 dB), generated the highest vehicular noise in the spatial distribution. In the eastern road segments, Eleme Flyover (98.1 dB) and Artillery Junction (95.5 dB) contributed the highest vehicular noise levels. In the northern segment, New Road (2311 vehicles) and Igwuruta (1566 vehicles) at the roundabouts, generated the highest vehicular traffic counts in the spatial distribution. Thus, among the eastern roads, Eleme Flyover (6735 vehicles) and Artillery Junction (5539 vehicles) contributed the highest vehicular counts in the area. The results showed that the northern and eastern segments of Port Harcourt metropolis had the highest level of vehicular traffic noise and traffic flow. Thus, the vehicular noise level values have exceeded the recommended 75 dB national and international health standards.The study recommended construction of more road network in the southern and western parts of Port Harcourt metropolis in order to decongest traffic flow and noise pollution in the northern and eastern segments of the city.

COVID-19 significantly altered individual patterns of interaction across the globe. The impediment on physical contact and emphasis on social distancing as measures of curbing its spread gave rise to new forms of interactions among individuals. In the ensuing new normal, digital life took the center stage, anchoring engaging and meaningful interactions of individuals in both public and private spheres. This study appraises the adoption of digital life in Nigeria during this period. Hinged on the technological determinism theory, the study examines the sudden digital migration in Nigeria and identifies the factors that facilitated the process, on the one hand, and the obstacles that inhibited it, on the other. Using secondary data derived from books, official websites, and media reports, the study has established that although the Nigerian society adopted digital life as alternative to face-to-face interactions out of expedience, a combination of systemic, structural, socioeconomic, and environmental factors constrained the process with grave implications on the overall (expected) impact to both individual and national developments. The study concludes that effective digitization in Nigeria requires a holistic approach toward addressing germane issues that retard socioeconomic development in the country—such as endemic poverty, structural inequality and class differences, uneven development between urban and rural communities, low computer literacy and information and communications technology (ICTs) access, poor electricity supply, poor global system for mobile communication (GSM) and Internet access, gender factor and vulnerable groups, and digital frauds—in order to create the enabling environment for productive digitization to thrive.

This research paper examined the changes in land use/ land cover of Abeokuta, Nigeria between 1984 and 2015 using Multi-Temporal Landsat Remote Sensing paired with Geographic Information System (GIS) techniques. The evaluation of the trend, rate and magnitude changes was the objectives of this study. Five Landsat satellite images of different dates, i.e., Landsat Thematic Mapper (TM) of 1984, 2001, 2006, 2011 and 2015 with spatial resolution ranging from 15, 30 and 60metres were obtained from National Aeronautics Space Administration(NASA),United State Geological Survey Website and GIS facility of Sioux Falls Website and quantify the changes over a period of thirty-one (31) years. Supervised classification methodology was applied to the acquired multi-band raster imageries using maximum livelihood technique in ERDAS Imagine 9.3. The images of the study area were classified into three (3) classes namely; vegetation, water body and built-up area and were overlay with vector maps of the study area generated in ArcGIS 10. The results show that for the period of 31years (1984-2015), vegetation which covered 76.20% of the total area has decreased to 39.29%, water body decreases from 6.63% to 1.89% while the built –up area which initially was 17.14% as at 1984 increased to 58.82%. The study, however, recommended that there is a need for a timely Land use/ Land cover mapping of the entire Abeokuta and its environs in order to reduce the effects of undiscrimate land utilization in the area. This will also facilitate necessary Land use planning and forestall the rising sprawl not only in Abeokuta but also in other urban centres.

Full textAbstract:
The changing environment, climate, and the increasing manifestation of disasters, has generated an increased demand for accurate and timely weather information. This information is provided by the National meteorological authorities (NMAs) through different dissemination channels e.g., using radios, Televisions, emails among others. The use of ICTs to provide weather information is recently gaining popularity. A study was conducted in three countries, namely Nigeria, Uganda, and South Sudan to assess the efficiency of an ICT tool, known as “Weather Information Dissemination System”. The study involved 254 participants (Uganda: 71; South Sudan: 133; and Nigeria: 50). The collected primary data were first quality controlled and organized thematically for detailed analysis. Descriptive statistics was used to provide quantitative analysis as well as content scrutinized for qualitative analysis. The results showed that there is a need for timely weather information to plan farming activities such as planting and application of fertilizers and pesticides as well as to manage flood and drought by the water sector and disaster management. Results further showed that the majority of the respondents have access to the technology needed to access weather and climate information. The respondents who received weather information from NMAs noted that the forecast was good. However, they further noted that there is more room for improvement especially with making the forecasts location-specific, ensuring mobile access is adequate in all regions, provision of weather information by SMS (in countries where this service is currently unavailable) and improved timing of the weather information. Finally, uncertainty about the accuracy of weather information and the weather information not meeting specific needs are key barriers to people’s willingness to pay for it (Uganda: 33.3%; South Sudan: 46.1%; and Nigeria: 33.3%). Improved collaborations between the NMAs, ICT service providers, policymakers and farmers will facilitate an effective approach to weather information access and dissemination. Innovative sensitization approaches through the media houses will enable better understanding of weather products and utilization, and access to enabling ICTs would increase access to weather forecasts

We present a dataset of the monthly cases of pipeline vandalism in Nigeria from January 2015 to January 2021. Data used in this study were collated from the Monthly Financial and Operations Reports (MFOR) of the Nigeria National Petroleum Corporation (NNPC). Each MFOR provides cases of pipeline vandalism during a 12-month span from five key locations; Mosimi, Kaduna, Port Harcourt, Warri, and Gombe. Recorded incidences of pipeline vandalism from these locations were summed and assembled into five groups; namely: historical data, prior-COVID-19, COVID-19 lockdown, and post-COVID-19 lockdown. The data were grouped based on dates. These dates were January 2015 to July 2019, August 2019 to January 2020, February 2020 to July 2020, and August 2020 to January 2021 respectively. The historical data were further sub-divided into four sub-groups based on the deployment (May 2016) of sophisticated weapons, satellite imagery, and geographical information system into the security apparatus to checkmate pipeline vandalism. The four sub-groups are sub-group A (one-year before deployment), sub-group B (the year of deployment), sub-group C (one-year after deployment), and sub-group D (two-years after deployment). The dates span for each sub-group is May 2015-April 2016, May 2016-April 2017, May 2017-April 2018, and May 2018-April 2019 respectively. After the deployment of GIS devices in May 2016, the accumulated national number of pipeline vandalism cases declined from 400 cases in January 2016 to 293 in February 2016, and 259 cases in March 2016 as opposed to 60, 49, and 94 cases in the same months in 2017; but over the years, 2017 to 2021 these methods have proved less effective, and cases of pipeline vandalism have risen once more. Similar changes in the number of cases and patterns were observed during the COVID-19 movement restrictions. From the dataset, it can be seen that COVID-19 influenced incidences of pipeline vandalism.

Full textAbstract:
Food security in Sub-Saharan Africa (SSA) is dependent on complex networks of interconnected actors and the flows of resources (biomass, capital) and information among them. However, the degree to which actors and value chains of different crops are in fact interconnected and their current systemic influence on food security are unclear. Therefore, the concept of “value webs” to better capture the complexity within the networks emerges. Biomass-based value webs of selected crops in Ghana, Nigeria, and Ethiopia are modeled using the systems analysis software iMODELER and by eliciting factors as well as their interconnections through participatory stakeholder workshops. Furthermore, a generic model was created compiling the country models to identify overarching system dynamics with supporting and hindering factors impacting food security in SSA. Findings from the country models show highly complex value webs, suggesting that the predominant value chain approach may oversimplify actual structures and resource flows in real life settings. However, few interconnections within the value webs link the actors and flows of different crops, contradicting predictions emerging from other research. Results from the generic model allow for a critical reflection on the relation between value web dynamics and food security policy in SSA. Current national and regional policy trends targeting market integration, mechanization, and reduction of post-harvest losses are supported by model results.

The issues related to the geographic information systems and spatial databases play an important role in toponymic research. The interest for this field is due to the expansion of the use of geographic data. This article examines the functions of toponymy, and analyzes the impact of historical events and processes, the change of socio-economic formations on toponymy. It highlights these patterns represented in the Azerbaijani toponyms system. Globalization and Internet technologies have necessitated an access to reliable spatial data. Therefore, the urgent task of regional onomastics is the creation of electronic regional databases, the formation of a single database linking toponymic data from all regions of Azerbaijan. This article substantiates the need for the creation of the National Toponymic Geographic Information System in Azerbaijan.

The purpose of this study is to investigate the failure and instability of slopes, control and evaluate treatments and create slope data in a geographic information system as a planning data base to determine the level of risk, hazard consequences and the distribution of slopes along the National road in Konawe Selatan district. In this study using the Bina Marga slope survey method, which is to provide a score or value for each parameter measured in the field and a database is made using a geographic information system (GIS) to state the level of slope risk using the Bina Marga standard value.
The results showed that the slopes spread on the Awunio – Lapuko and Lainea – Awunio National roads were dominated by artificial slopes, namely 4 embankment points and 5 excavation points and 1 natural slope point. From the results of the investigation and data collection on the slopes, the data is processed using the formula R = 0.9.H + C. where R is the risk level value, H is the hazard value and C is the consequence value. The conclusion from the above research results is that the slopes at the study site are dominated by artificial slopes with slope characteristics of soil, sand and weathered rock so that the slopes are unstable and have a high level of risk.

Full textAbstract:
TIANDITU (Map World) is the public version of the National Platform for Common Geospatial Information Service, and the travelling channel is TIANDITU-based geographic information platform for travelling service. With the development of tourism, traditional ways for providing travelling information cannot meet the needs of travelers. As such, the travelling channel of TIANDITU focuses on providing travel information abundantly and precisely, which integrated the geographic information data of TIANDITU Version 2.0 and the authoritative information resources from China National Tourism Administration. Furthermore, spatial positioning, category and information query of various travelling information were offered for the public in the travelling channel. This research mainly involves three important parts: the system design, key technologies of the system design and application examples. Firstly, this paper introduced the design of TIANDITU-based geographic information system for travelling service, and the general and database design were described in detail. The designs for general, database and travelling service above should consider lots of factors which illustrated in the paper in order to guarantee the efficient service. The process of system construction, the content of geographic information for travelling and system functions of geographic information for travelling are also proposed via diagram in this part. Then several key technologies were discussed, including the travelling information integration for main node and among nodes, general architecture design and management system for travelling channel, web portals and system interface. From the perspective of main technologies, this part describes how TIANDITU travelling channel can realize various functions and reach the requirements from different users.

Abstract. Today, more and more geospatial services are provided by the governments and enterprises to share various geographic information data and functions, and services-based application integration has become a trend. However, many problems existed in the geo-platform for Geographic information sharing while providing services in the form of API, such as the coexistence of different versions of the same service, similar service routes of different APIs, cluttered service protocols, and complex authority management, that makes the integration among different geographic information services difficult and reduces the development efficiency. There are already some API gateway technologies to solve the problem, but the characteristics of geospatial services are not considered in the existing product. To address these problems, this paper proposed a high-currency geospatial service gateway system for National Geo-Information Service Platform based on the opensource framework of Kong for realizing the unified management and authorized open. The system provides the whole lifecycle management and fine-grained control for the service, and the functions such as unified geospatial service access, protocol conversion, service management, authorization verification, rate limiting, and security protection are also equipped. The system has been released and integrated in the National Geo-Information Service Platform, supporting hundreds of millions of service invocation every day. The result proves it simplifies geospatial services management, deployment, and application, and benefits the exchanging and sharing of geographic information.

The development of applying database management applications is currently underway within Geographical Information Systems (GIS) applications in the Sultanate of Oman.The establishment of a national database management system in Oman is considered as the backbone that is required within the Geographic Information System project in Oman. The principal of the GIS project in Oman was built upon unifying the used software packages over the sultanate which is ARC/INFO as GIS Package and ORACLE as database management software. These packages are used within the different participating Ministries in the GIS project in Oman.The participating ministries will handle information that are shared between them. The shared information among the different ministries is the attributed data which is defined as descriptive information extracted from geographic features that usually existed on the topographic maps and the ministries maps (utility maps). The map features can be classified into different layers according to the principles of ARC/INFO GIS Package. Accordingly, the main objectives of this research paper is to explain the technique proposed for establishing a national database management system that can handle and manage the shared information amongst the participating ministries in the project. The proposed database design will be made using the ORACLE database management system. Moreover, the paper will handle a proposed idea for linking the geographic map layers with the corresponding attributed database in order to create Geographic Information System applications. As a Conclusion, it is Proposed that all the government GIS departments in the Sultanate will share the same information within a unique national database management which can be considered one of the major benefits in applying database management in the field of Geographic Information Systems.

AbstractIn the southeastern United States, Amaranthus, or pigweed species, have become troublesome weeds in agricultural systems. To implement management strategies for the control of these species, agriculturalists need information on areas affected by pigweeds. Geographic information systems (GIS) afford users the ability to evaluate agricultural issues at local, county, state, national, and global levels. Also, they allow users to combine different layers of geographic information to help them develop strategic plans to solve problems. Furthermore, there is a growing interest in testing free and open-source GIS software for weed surveys. In this study, the free and open-source software QGIS was used to develop a geographic information database showing the distribution of pigweeds at the county level in the southeastern United States. The maps focused on the following pigweeds: Palmer amaranth, redroot pigweed, and tall waterhemp. Cultivated areas and glyphosate-resistant (GR) pigweed data were added to the GIS database. Database queries were used to demonstrate applications of the GIS for precision agriculture applications at the county level, such as tallying the number of counties affected by the pigweeds, identifying counties reporting GR pigweed, and identifying cultivated areas located in counties with GR pigweeds. This research demonstrated that free and open-source software such as QGIS has strong potential as a decision support tool, with implications for precision weed management at the county scale.

Spatial referencing by geographic identifiers.
The main direction of development of topographic and geodetic activity in Ukraine is the development of the national spatial data infrastructure based on the principles of geoinformation approach. The national spatial data infrastructure is seen as a system of integration of geospatial data of different origins from different sources, and most importantly from different areas of activity. The system of integration of heterogeneous data acquires special value at connection of a set of basic data with the thematic data which provide an array of attributive information from various kinds of activity. It is through geographic identifiers that geospatial coordinate descriptions of features are linked to an array of attribute data that does not have a direct positioning. Geographic identifiers can be the following: codifier of administrative-territorial units and territories of territorial communities, cadastral number of the land plot, address, geographic name, etc.
Therefore, the aim of the article is to study the requirements for the use of geographic identifiers for the integration of sets of basic and thematic geospatial data of the national geospatial data infrastructure in accordance with DSTU ISO 19112:2017 (ISO 19112:2003, IDT).

The increasing demand for freshwater has been on the increase as a result of geometric population growth, erratic climate change and urbanization has necessitated more attention and reliance on groundwater resources most especially in Ado-Ekiti, Nigeria. This necessitates the urgent need for judicious management of available groundwater resources to meet the freshwater requirements in the studied area. Geographical Information System (GIS) and Remote Sensing (RS) techniques were used to map out the groundwater recharge potential of the studied area. Google Earth and Land Satellite (LANDSAT) 7 sensor of Enhanced Thematic Mapper Plus (ETM+), path 191 and row 55 were used to acquire the satellite imageries of Ado-Ekiti. Using high resolution imageries, a Digital Elevation Model (DEM) was developed with Surfer 8 and ArcGIS 10.0 softwares to identify areas with high, medium and low groundwater recharge zones in the studied area. The elevation, slope, land use/ land cover, drainage density, lineament density, lithology, flow direction, flow length and flow accumulation maps of the study area were generated by using the DEM. The groundwater recharge potential was obtained by overlaying all the thematic maps that affected the groundwater distribution. Each thematic map was weighted according to its effect on groundwater infiltration. The results showed that areas with high lineament density, long flow length, high flow accumulation, high drainage pattern, low slope (lowland region) and vegetation have high groundwater recharge potential, and areas with medium lineament density, flow length, flow accumulation, drainage density, slope and sparse vegetation, respectively have moderate groundwater recharge potential while areas with low lineament density, short flow length, low flow accumulation, low drainage density, high slope (highland region) and sparse vegetation have low groundwater recharge potential. Better information on groundwater recharge potential of the studied area was provided via easily read and accessible maps generated from remotely sensed data and ArcGIS 10.0 software. The results also revealed that geology survey should be carried out to validate the results.

This study assessed the location of landfills in Zaria LGA of Kaduna State by the use of GIS and RS. Increase in population has brought rapid urbanization, which in turn accelerates the rate of waste generation. This caused indiscriminate disposal of waste in landfills within residential centers, which are not properly located; these are source of disease, pollution, and unaesthetic. Hence, all the landfills in the study area were identified (27 landfills) and their locations or spatial data recorded using a GPS. GIS was employed for mapping and spatial analysis using buffering of 500 meters’ proximity to residential houses in order to designate the proper and improperly located landfills. Results of the GIS analyses indicated 2 landfills were properly located, while the remaining 25 were not. Based on the results of this study it is recommended that all the improper landfills should be abandoned and banned by the government; new landfills should be designated at outskirts of the town at distances of few kilometers from the residential houses; pickup points should replace the abandoned landfills, and new ones also be designated for efficient waste management.
