On-Foot Content Tourism Support System in Urban Tourist Destinations of Japan

It has also become possible for people to easily acquire tourism information that matches their own particular tastes using the internet, so tourism has taken a more diverse range of forms. One of these is “content tourism” that became popular in recent Japan. Sgains such a backdrop, the present study aimed to design, develop, operate and evaluate a system that integrated three subsidiary systems including Web-geographic information systems (GIS), a tourism information system and social networking service (SNS) in order to support walking-based content tourism. This made it possible to create sightseeing routes and to submit, store, and view tourist attraction information. Additionally, the system was operated for one month in Chofu City, Tokyo Metropolis, and the total number of users was 42. During the operation period, 12 new sightseeing routes were created and 30 new tourist attractions were submitted. Based on the results of the web questionnaire survey, users highly evaluated the key functions of the system and the overall system. However, of those key functions, evaluations were somewhat low for the ease of operation of the creation function of sightseeing route, so the improvements must be made. From the results of the access log analysis of users’ log data, the total number of sessions in this system was 134, 64% used PCs, 36% used mobile devices, Therefore, the approach of designing the system such that the same functions could be used regardless of the type of device one is using was an effective design approach.

Improving Participation in the German Search for a Nuclear Waste Repository Site: a WebGIS as a Transdisciplinary Approach to Support Dialogue?

Abstract. The political and social debate on nuclear energy in Germany has been characterized for many decades by a high potential for conflict and dissatisfaction. In particular, the controversies surrounding the Gorleben salt dome achieved international attention and altered the relationship between the population and political decision makers at the local up to international levels. With the Site Selection Act from 2013 (StandAG, first revision 2017) a new approach was selected in order to find a participative, inclusive and transparent search process for the best possible site of a repository for highly radioactive waste in Germany. In connection with this a self-learning process was proclaimed, based on a white (unprejudiced) map, which aimed to give the general public an active role; however, even the first interim report of the Federal Company for Radioactive Waste Disposal (BGE) and the publication of the multicolored map, in which geologically suitable areas were extensively shown, revealed a massive potential for conflict. Many citizens and activists, who had already protested against the Gorleben salt dome, in this early phase of the process criticized the lack of transparency and opportunities to voice an opinion on possible site regions. In order to counter these criticisms, the possibilities for a web geographic information system (WebGIS) application (interactive map) as an online platform were analyzed (Walkobinger and Tauch, 2018; Brown and Kyttä, 2018). The aim was to virtualy present available geodata (Chwalisz, 2021), which enabled people to contribute to spatial information (geological, superficial) and therefore to achieve an interaction and participation option with respect to the possible site regions. For this, available geodata relevant for the site search process, such as subareas (BGE, 2020), nuclear power stations (active/inactive, research stations etc.), storage facilities (repository, central, intermediate storage etc.), historically relevant sites (sites of protest, uranium-enrichment and preparation plants etc.) and basic data on orientation were used. Based on this, two possibilities for participative interaction were analyzed: (1) the inclusion of spatially located notes that contain own experiences or local knowledge (e.g. reports, concerns, suggestions, own expert opinions) and (2) the initiation of a platform for a spatially located discussion. Against the background of transdisciplinary research, the aim was to evaluate the participative value of this application in an iterative process, in which the research process is supported by an accompanying group from civil society. For this panel we want to present our results from the transdisciplinary research process. In addition to testing the suitability of such a participation mode, we want to analyze where problems arise and which information is necessary or can lead to conflicts (Griffin, 2020). Finally, we want to gain information on how such participation modes influence the quality of the dialogue and how they contribute to an overall perception of a legally acceptable process (Rzeszewski and Kotus, 2019).

Development of a web-geographical information system application for plotting tuberculosis cases.

In the last few decades, public health surveillance has increasingly applied statistical methods to analyze the spatial disease distributions. Nevertheless, contact tracing and follow up control measures for tuberculosis (TB) patients remain challenging because public health officers often lack the programming skills needed to utilize the software appropriately. This study aimed to develop a more user-friendly application by applying the CodeIgniter framework for server development, ArcGIS JavaScript for data display and a web application based on JavaScript and Hypertext Preprocessor to build the server's interface, while a webGIS technology was used for mapping. The performance of this approach was tested based on 3325 TB cases and their sociodemographic data, such as age, gender, race, nationality, country of origin, educational level, employment status, health care worker status, income status, residency status, and smoking status between 1st January 2013 and 31st December 2017 in Gombak, Selangor, Malaysia. These data were collected from the Gombak District Health Office and Rawang Health Clinic. Latitude and longitude of the location for each case was geocoded by uploading spatial data using Google Earth and the main output was an interactive map displaying location of each case. Filters are available for the selection of the various sociodemographic factors of interest. The application developed should assist public health experts to utilize spatial data for the surveillance purposes comprehensively as well as for the drafting of regulations aimed at to reducing mortality and morbidity and thus minimizing the public health impact of the disease.

A Web GIS-Based Integration of 3D Digital Models with Linked Open Data for Cultural Heritage Exploration

In recent years, considerable efforts have been made by cultural heritage institutions across the globe to digitise cultural heritage sites, artifacts, historical maps, etc. for digital preservation and online representation. On the other hand, ample research projects and studies have been published that demonstrate the great capabilities of web-geographic information systems (web-GIS) for the dissemination and online representation of cultural heritage data. However, cultural heritage data and the associated metadata produced by many cultural heritage institutions are heterogeneous. To make this heterogeneous data more interoperable and structured, an ever-growing number of cultural heritage institutions are adopting linked data principles. Although the cultural heritage domain has already started implementing linked open data concepts to the cultural heritage data, there are not many research articles that present an easy-to-implement, free, and open-source-based web-GIS architecture that integrates 3D digital cultural heritage models with cloud computing and linked open data. Furthermore, the integration of web-GIS technologies with 3D web-based visualisation and linked open data may offer new dimensions of interaction and exploration of digital cultural heritage. To demonstrate the high potential of integration of these technologies, this study presents a novel cloud architecture that attempts to enhance digital cultural heritage exploration by integrating 3D digital cultural heritage models with linked open data from DBpedia and GeoNames platforms using web-GIS technologies. More specifically, a digital interactive map, 3D digital cultural heritage models, and linked open data from DBpedia and GeoNames platforms were integrated into a cloud-based web-GIS architecture. Thus, the users of the architecture can easily interact with the digital map, visualise 3D digital cultural heritage models, and explore linked open data from GeoNames and DBpedia platforms, which offer additional information and context related to the selected cultural heritage site as well as external web resources. The architecture was validated by applying it to specific case studies of Australian cultural heritage and seeking expert feedback on the system, its benefits, and scope for improvement in the near future.

Implementation of BIM + WebGIS Based on Extended IFC and Batched 3D Tiles Data: An Application in RCC Gravity Dam for Republication of Design Change Model

The construction of hydropower project is a complex management process, whose management covers the entire construction site. Building information modeling (BIM) + Web Geographic Information System (WebGIS) is an effective means to solve the management of the construction site and main structures. Industry foundation classes (IFC) is commonly used in architecture, engineering and construction (AEC) industry as a standard for BIM data exchange. However, as the components of hydropower projects have not been included in IFC standards, IFC needs to be extended in application. At the same time, WebGIS pays more attention to display whole scene and ignores the processing of high-precision models. There will be deficiencies in network transmission and browser rendering in WebGIS environment of elaborate BIM model. Therefore, the batched three dimensions (3D) Tiles data format, which uses Web Graphics Library (WebGL) as the standard for 3D model rendering, has been widely considered in recent years. At present, in the field of BIM and GIS fusion, the conversion of extended IFC to 3D Tiles data is still blank, and none of the current BIM modeling software has the ability to export the components of hydropower projects. This paper proposes an extended IFC export method based on Autodesk Revit and a data exchange from extended IFC to batched 3D Tiles. Finally, the effectiveness of this method is verified by a design modification case of roller compacted concrete (RCC) gravity dam.

3D Tiles-Based High-Efficiency Visualization Method for Complex BIM Models on the Web

Geographic data visualization is an important research area of Web Geographic Information System (GIS). Owing to the detailed subassemblies and exhaustive knowledge database, building information modeling (BIM) plays an important role in geospatial research and industries. The integration of BIM and GIS contributes to the smooth visualization, quick construction, and efficient management of geographic data. However, there are very few methods that can yield high-efficiency data transmission and visualization for complex BIM models while maintaining the integrity of the internal subassembly structure and attributes. To overcome this issue, this paper proposes a 3D Tiles-based visualization method for complex BIM models on the Web-based 3D model viewer. This method is adopted to partition the BIM model according to its assembly without simplifying the BIM model, by using a tiling method for 3D models based on a degraded R-tree, which accounts for the size of tiles. Subsequently, we introduce the “Mask Filter,” a level of detail method that is used to layer the BIM model. Conducting a series of contrast experiments, the result indicates that this method is efficient and feasible, which significantly improves visualization performance of complex BIM with mass data in the geospatial scene and facilitates the integration of Building Information Modeling and Geographic Information System.

This system was designed and implemented using Laravel, PHP, MySQL, Java Script, Bootstrap, and Leaflet. This system has also been tested by tourists and the results are that every tourist can enjoy the features of describing tourist attractions, destination routes, and making visit schedules.

THE USE OF GEOGRAPHIC INFORMATION SYSTEM FOR FLOOD PREDICTIONS

The article examines the issue of using geographic information systems (GIS) and WEBGIS technologies to predict areas likely to be flooded. Probabilistic flood hazard maps (0.5%, 0.1% and 1% flood risks) were used, obtained from a model installation in an area subject to flood risk, in this case, the municipality of Ungheni in the Republic Moldova, which has been flooded in the past. The application of GIS technologies is necessary to prevent floods affecting households, infrastructure and to minimize its effects. For this purpose, were analyzed the previous floods that occurred in the region. Also were applied and overlaid thematic digital maps such as Land Use, river network, DTM, Delineation Methodology of water bodies which represents the transposition of the EU Water Framework Directive 2000/60/EC and at the end were uploaded on an ESRI Web GIS platform http://www.dbga.md/siga.html. The Coordinate system used here was WGS-84.

Sightseeing Navigation System from Normal Times to Disaster Outbreak Times within Urban Tourist Areas in Japan

In tourist areas, it is necessary to prepare a method that supports tourists’ activities by providing information concerning disaster support facilities during normal times, in addition to sightseeing spots and tourism-related facilities, because there is a risk of confusion during disasters, as tourists are not aware of the locations of disaster support facilities. The present study aims to develop a navigation system that supports the activities of users during both normal times and disasters by integrating augmented reality (AR) and web geographic information systems (Web-GISs), as well as by using pictograms. The system can not only effectively provide users with information concerning sightseeing spots and tourism-related facilities but also information concerning disaster support facilities. The system was operated over a period of 6 weeks in Chofu City, Tokyo Metropolis, Japan. Based on the results of a questionnaire survey for 60 users, the system was highly evaluated for its originality in terms of displays and functions using pictograms, navigation using AR, and obtaining information during disasters. Additionally, based on the results of access log analysis, the system was continuously utilized by users during the operation period. Therefore, by continuously operating the system, it can be expected that users will further utilize each function of the system.

Structure-Level 3D Building Model Encoding Method for Progressive Transmission

Progressive encoding and transmission, i.e., a crucial technical foundation of 3D Web Geographic Information Systems (WebGIS), addresses the contradiction between massive 3D building data and limited network transmission capacity. Most progressive encoding algorithms, taking vertices, edges or triangles as encoding units, may break the inherent geometric and topological characteristics of 3D building models. Thus, a novel 3D building model encoding method that can maintain the internal characteristics is proposed, which can be used for high-efficiency progressive transmission. With this method, each building is decomposed into three types of fundamental structures: main structure, independent structure and attached structure. A structural topology graph (STG) was constructed based on the connections among structures. Guided by STG, one or more structures were wrapped as the smallest incremental transmission unit, denoted as transmission node. When requested, the real-time position of viewpoint, orientation and visual importance of nodes are used to pick up expected nodes for responding. The results confirm that the proposed method can better maintain the geometric and topological characteristics while encoding 3D building models. While serving for transmission, the proposed method not only effectively reduces the transmission load, but also provides users with a better consistency experience on the building appearance at different simplification levels.

COVID-19 Monitoring Application for Malaysian Armed Forces and National Security Council

The development of geospatial technology plays a significant role in online sharing of geospatial data and virtual updating. The National Security Council (NSC) and the Ministry of Health (MOH) are the two leading agencies responsible for handling Covid-19 pandemic in Malaysia. The government had stringently enforced various schemes and Standard Operating Procedures (SOP) to prevent the spread of the disease. As a support, the Department of Survey and Mapping Malaysia (JUPEM) through its Geospatial Defence Division (BGSP), has developed a Web Geographical Information System (GIS) application using its Defence Geospatial Information Management (DGIM) platform. A collaboration of geospatial data services has been made among government entities and security agencies in providing the latest information on COVID-19. JUPEM has also developed a Joint Common Operating Picture (JCOP) application for the NSC and Malaysian Armed Forces (MAF) to strengthen its efforts to monitor and to avoid spreading the virus any further.

GIS Open-Source Plugins Development: A 10-Year Bibliometric Analysis on Scientific Literature

The advent of Geographical Information Systems (GIS) has changed the way people think and interact with the world. The main objectives of this paper are: (i) to provide an overview of 10 years (2010–2020) regarding the creation/development of GIS open-source applications; and (ii) to evaluate the GIS open-source plugins for environmental science. In the first objective, we evaluate the publications regarding the development of GIS open-source geospatial software in the last 10 years, considering desktop, web GIS and mobile applications, so that we can analyze the impact of this type of application for different research areas. In the second objective, we analyze the development of GIS open-source applications in the field of environmental sciences (with more focus on QGIS plugins) in the last 10 years and discuss the applicability and usability of these GIS solutions in different environmental domains. A bibliometric analysis was performed using Web of Science database and VOSViewer software. We concluded that, in general, the development of GIS open-source applications has increased in the last 10 years, especially GIS mobile applications, since the big data and Internet of Things (IoT) era, which was expected given the new advanced technologies available in every area, especially in GIS.

Field Reporting Irrigation System via Smartphone

Irrigation is one of the backbones in the field of agriculture. The role of technology in the industrial era 4.0 has increased tremendously in irrigation management systems. Areas, limited internet access, and validation of activity reports are separate issues in monitoring the performance of irrigation field workers in real-time. Therefore, we built a reporting system that is equipped with location tracking using the Smartphone Global Positioning System (GPS) and the Web Geographic Information System (WebGIS) application. This field reporting system starts from the report input form on the Android app that detects location coordinates automatically. Reports are stored in an offline SQLite database and sent to the MySQL database server online through the data synchronisation process. From the server-side, information displayed through the WebGIS application. This field reporting is more efficient in monitoring the performance of irrigation systems in real-time.

Decision Making in the 4th Dimension—Exploring Use Cases and Technical Options for the Integration of 4D BIM and GIS during Construction

In both the Geospatial (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of geo-data and BIM-data is beneficial and a crucial step towards solving the multi-disciplinary challenges of our built environment. The result of this integration—broadly termed GeoBIM—has the potential to be particularly beneficial in the context of the construction of large infrastructure projects, which could make use of data relating to the larger spatial extents typically handled in geographical information systems (GIS) as well as the detailed models generated by BIM. To date, GeoBIM integration has mainly been explored for buildings, in a 3D context and for small projects. This paper demonstrates the results of the next level of integration, exploring the addition of the fourth dimension by linking project schedule information to create 4D GeoBIM, examining interoperability challenges and benefits in the context of a number of use cases relating to the enabling works for a major commercial infrastructure project. The integrating power of location and time—knowing where and when data relate to—allows us to explore data interoperability challenges relating to linking real world construction data, created using commercial software, with other data sources; we are then able to demonstrate the benefits of 4D GeoBIM in the context of three decision making scenarios: examining the potential for prioritisation of noise mitigation interventions by identifying apartments closest to the noisiest construction process; development of a 4D location-enabled risk register allowing, for example, work to continue underground if a risk is specific to the top of a building; ensuring construction safety by using 3D buffering to ensure that the required distances between moving construction equipment and surrounding infrastructure are not breached. Additionally, once integrated, we are able to ‘democratize’ the data—make it accessible beyond the BIM and GIS expert group—by embedding it into a 3D/4D open source Web GIS tool.

A GPS-enabled portable air pollution sensor and web-mapping technologies for field-based learning in health geography

ABSTRACT Geographic technologies and perspectives are important for understanding health issues because places and locations influence human health and diseases. Despite the increasing use of a geographic information system (GIS) in health research, and the explosion of new and emerging technologies, little is known about their potential as educational tools for health geography and the effectiveness for student learning. Focusing on air-sensing and web GIS technologies, this article presents an innovative pedagogical strategy to integrate these technologies as tools for field-based learning in health geography and discusses the effectiveness and challenges of this teaching method. A class project, undertaken in a university health geography course, was developed to offer students hands-on training and real-world experience with state-of-the-art technologies. It consisted of (1) a lecture and pre-fieldwork training; (2) field data collection using a low-cost, GPS-enabled portable air-pollution sensor; (3) data visualization using web GIS; and (4) sharing the findings through a web-based story map application. The successful implementation of the teaching method, as indicated by students’ positive comments, demonstrated that such class projects can reinforce students’ knowledge of air pollution and health risks; improve their technical, critical thinking, and research skills; and prepare students for entering a technology-driven society.

Design of Yunnan Province Soil Environmental Quality Monitoring and Analysis Platform Based on WebGIS

The state and government departments will produce a large amount of soil survey data in the process of soil environmental pollution investigation. The format of soil data has diversified and multi-scale spatial characteristics. Due to the lack of a unified soil environmental pollution management platform in Yunnan Province, the storage of soil survey data is disorderly and messy. The data cannot be well-informed and scientifically analyzed, resulting in the inability to provide accurate and comprehensive soil environmental quality for all levels of government management data. In order to effectively solve this problem, taking soil heavy metal pollution survey sampling points in Yunnan Province as an example, this paper uses web geographic information systems (GIS) technology to design a set of soil environmental monitoring and analysis platforms that describe data sources, data collection, data analysis and visualization. The platform has established a scientific and rigorous data analysis method, which can uniformly convert and store historically scattered data and conduct unified management and analysis of survey data.

Implementation of serverless cloud GIS platform for land valuation

ABSTRACT Cloud computing enables performing computations and analysis tasks and sharing services in web-based computer centres instead of local desktop systems. One of the most used areas of cloud computing is geographic information systems (GIS) applications. Although Desktop GIS products are still used in the community frequently, Web GIS and Cloud GIS applications have drawn attention and have become more efficient for users. In this study, a serverless Cloud GIS framework is implemented for the land valuation platform. In order to store, analyse, and share geospatial data, the Aurora Serverless PostgreSQL database is created on Amazon Web Services (AWS). While adopting Aurora Serverless PostgreSQL as a database management system, a simple point in polygon analysis conducted to compare the performances with Amazon Relational Database Service (RDS) instance. Results showed that the serverless database responded to the query faster and scaled up during high workload to decrease latency. Hence, parcel vector data, which conveys ownership information and land values attributes, is shared directly from the PostGIS database as vector tiles. Besides S3 and AWS Lambda services are used for storing and disseminating raster-based land value map tiles. To visualize all shared data and maps through a web browser, open source web mapping library Mapbox GL JS is used.

Nepalese landslide information system (NELIS): a conceptual framework for a web-based geographical information system for enhanced landslide risk management in Nepal

Abstract. Comprehensive and sustainable landslide risk management, including the identification of areas susceptible to landslides, requires responsible organisations to collaborate efficiently. Landslide risk management efforts are often made after major triggering events, such as hazard mitigation after the 2015 Gorkha earthquake in Nepal. There is also a lack of knowledge sharing and collaboration among stakeholders to cope with major disaster events, in addition to a lack of efficiency and continuity. There should be a system to allow for landslide information to be easily updated after an event. For a variety of users of landslide information in Nepal, the availability and extraction of landslide data from a common database are a vital requirement. In this study, we investigate the requirements to propose a concept for a web-based Nepalese landslide information system (NELIS) that provides users with a platform to share information about landslide events to strengthen collaboration. The system will be defined as a web GIS (geographic information system) that supports responsible organisations in addressing and managing different user requirements of people working with landslides, thereby improving the current state of landslide hazard and risk management in Nepal. The overall aim of this study is to propose a conceptual framework and design of NELIS. A system like NELIS could benefit stakeholders involved in data collection and landslide risk management in their efforts to report and provide landslide information. Moreover, such a system would allow for detailed and structured landslide documentation and consequently provide valuable information regarding susceptibility and hazard and risk mapping. For the reporting of landslides directly to the system, a web portal is proposed. Based on field surveys, a literature review and stakeholder interviews, a structure of the landslide database and a conceptual framework for the NELIS platform are proposed.
