Garbage is a problem that needs an in-depth study in urban areas because the development of an area has consequences on increasing population density, facilities and infrastructure, public services, and other aspects that impact increasing the volume of waste. The distribution of temporary waste shelters (TPS) in each area is still insufficient to accommodate the volume of waste, and its availability is inadequate. The purpose of this study is to model spatial data through spatial analysis using artificial intelligence methods in classifying the development of integrated temporary shelter locations (TPST) and regional integrated temporary shelters (TPST Regions) by utilizing Web-based technology (Geographical Information System (Web-GIS). The Artificial Neural Network method with the Backpropagation algorithm is used for the spatial analysis process based on the parameters of the population, the amount of organic and inorganic waste, the amount of industrial waste, and the volume of the TPST and Regional TPST capacity. The spatial analysis results using the Artificial Neural Network method obtained an accuracy value of 7171.02%. The results of this study can be the basis for Department of Environment and Cleanliness policies for the development of TPST and TPST areas with information coverage at the village level., Permasalahan sampah memerlukan perhatian serius akhir-akhir ini. Perkembangan daerah seiring dengan meningkatknya kepadatan penduduk, sarana dan prasarana, pelayanan publik, dan aspek lainnya serta berdampak pula pada peningkatan volume sampah. Persebaran tempat penampungan sementara (TPS) sampah yang disediakan di setiap daerah tidak sebanding dengan pertambahan volume sampah. Tujuan penelitian ini adalah untuk melakukan pemodelan data spasial melalui analisa spasial menggunakan metode kecerdasan buatan dalam mengklasifikasikan pengembangan lokasi penampungan sementara terpadu (TPST) dan tempat penampungan sementara terpadu kawasan (TPST Kawasan) dengan memanfaatkan teknologi SIG (Sistem Informasi Geografis) berbasis Web (Web-GIS). Metode Jaringan Syaraf Tiruan dengan algoritma Backpropagation digunakan dalam proses analisa spasial berdasarkan parameter jumlah penduduk, jumlah sampah penduduk organik dan an-organik, jumlah sampah industri, serta volume daya tampung TPST dan TPST Kawasan. Hasil analisa spasial dengan metode Jaringan Syaraf Tiruan memperoleh nilai akurasi 7171,02 %. Hasil penelitian ini dapat menjadi dasar kebijakan Dinas Lingkungan Hidup dan Kebersihan (DLHK) untuk pengembangan lokasi TPST dan TPST Kawasan dengan cakupan informasi pada level kelurahan atau desa.

The zonation system is one of the efforts of the Indonesian Government to improve the quality of education services continuously, but the implementation is still considered less useful. Some areas were still grouped into the different zone from the original. Based on this problem, the solution needed for the zonation mapping of each school so that the apparent zonation limit can be resolved. An application that can map schools in an area based on housing for prospective students is a solution that can be considered at this time. This research showed the implementation of Voronoi diagrams to cluster the area based on the school position within Bengkulu City. The system was also capable of mapping the residential of the student address to match the choice for registration in available secondary school and senior high school. The implementation of the system showed a better result for school zonation over Bengkulu City based on web geographic information system (Web GIS). Furthermore, the comparison analysis over the existing system also showed that the performance of the Voronoi diagram for school zonation the method could solve the problem of the overlapping zonation with Radius method. Three hundred fifty students validated this system to show the performance of this method. The result showed that 72.05% of students matched the first choice, while 27.95% of students matched the second choice. This research showed the analysis of the value of this gap appeared due to the student preferences and school capacity factors.

The European building stock needs fast and affordable digitalization for facilitating the renovation process to achieve higher energy efficiency in buildings and in houses. Most of the residential buildings built between 1925-1975 lack proper documentation and digital building information, as opposed to newer buildings. Digital building information (geometry and attribute data) is required to plan retrofitting projects or renovations of facades. This work can only be efficient if Building Information Modelling (BIM) is available for stakeholders (owners, architects, contractors etc.). Whereas city planners of municipalities or social housing companies are striving to manage their properties and building portfolio on multiple scales, these stakeholders are seeking an approach that enables spatial planning, efficient asset management and energy consumption and management services for their buildings. In a EUREKA labelled project (E!12649 Ready2BIM) three partners worked together, two from Hungary (Geonardo Ltd. and SZTAKI) and one from Germany (CAALA GmbH).

The fisheries sector, with its immense contribution to national welfare in terms of economic benefits and food security, is beset by various problems such as excessive and destructive forms of fishing that push the resources and the industry to a critical state. In response, the National Stock Assessment Program (NSAP) was created as a regular program of the Bureau of Fisheries and Aquatic Resources (BFAR) that intends to generate reliable data as a basis for the formulation of policies for the management and conservation of the country’ capture fisheries resources in order to attain resource assessment and management. However, information on fish stocks recorded in NSAP is not publicly accessible. Thus, there is a need to develop a web-based system that can be openly explored by stakeholders, fisherfolk, and the populace for informative purposes and to raise awareness about the status of the Philippine fishery. A web-based Geographic Information System (GIS) with analytical and centralized system administration was developed to answer the limitation of the previous program. The research used the agile methodology as its development cycle and adopted ISO 25010 as its evaluation for software product quality standards. Based on the assessment of the end users, and IT experts, the system scored an excellent status with highly acceptable quality, which means that the study methodology was successfully implemented. Moreover, this research paper is important since it can be used as a reference for the continuation of development in relation to fishery management. The product result of the study is significant since the system can contribute to managing and monitoring the country’s fish stocks., CITE AS: Dionisio, J. K., & Sonza, R. (2022).

Water is one of the most important requirements in daily life, which represents the largest part of the Earth. As a result of the economic, industrial and social development in most countries led to increased pollution in water resources. It is, therefore, necessary to monitor water quality continuously to prevent a future catastrophe that adversely affects the quality and quantity of water wealth. Geographic Information System (GIS) is used in various fields to monitor, analyze data collected from different geographical locations. Integration of GIS and other technologies has become an indispensable tool. This gives us direct control over solution expansion, cost reduction, powerful complex case analysis as well as increased accuracy and efficiency of geospatial data. In recent years, many combinations of GIS with different technologies such as remote sensing, wireless sensor networks, internet of things approaches have been proposed due to the rapid progress of technology development in many applications. However, in last several years, there is no survey paper has been published about water quality using the integration of GIS and other technologies. Therefore, this paper investigates the status of continuous search in the field of GIS and its integration with other technologies (Remote Sensing, Internet of Things, Web, etc.) for water quality management and monitoring to maintain the water resources in a proper way. As conclusions, the integration of the GIS with these technologies is a powerful platform for analyzing and processing big data and mapping geographic remotely in less time, less cost, high speed and with more accurate details and in real time compared to traditional geographic information systems. This paper also highlights future research trends about the cooperation of GIS with other technologies for matters that are related to water quality. Doi: 10.28991/HIJ-2021-02-03-10 Full Text: PDF

The article is devoted to the description of the web-GIS for mapping fire regimes in the Pechora-Ilych reserve and its environs. The main purpose of the resource is to provide the results of mapping fire regimes in the designated area to a wide range of researchers in an accessible form. Web-GIS allows organizing and storing the received thematic spatial data. The resource performs research and educational functions. The structure of the web-GIS includes the following sections: the study area, fire frequency indicators, fire regimes, fire regime condition class, and fire cycles. The web GIS was created using the ArcGIS StoryMaps tool on the ArcGIS Online platform. All sections use data from the ArcGIS Living Atlas of the World. Web-GIS allows receiving reference information about the indicators of fire frequency, fire cycles and regimes, as well as their deviations within the boundaries of the Pechora-Ilych nature reserve, district forestries, and spatial units. In particular, the results of a retrospective statistical analysis of forest fire indicators within spatial units (fire frequency, mean fire interval, etc.) are available for users.

Systeme zur Entscheidungsunterstützung haben große Potenziale, Planungsprozesse im Rahmen der Daseinsvorsorge zu verbessern.

In einem Workshop haben Akteure aus Planungspraxis, Wissenschaft und Wirtschaft anhand von konkreten Fragen aus der Planung die Anwendung der web-basierten Tools „Daseinsvorsorgeatlas Niedersachsen“ und „GOAT 3.0“ diskutiert. Im Rahmen von Arbeitsgruppen wurden die Anwendbarkeit, Indikatoren und Modellierungen sowie Hindernisse für eine Integration in Verfahren erarbeitet.

Naturally, watershed has a function to accomodate and store water from rainfall to the lake or to the sea. It is affected by land activities and shaped as a boundary of topographic land and as a separator from the sea. Managing the area is one of essential steps for further environment assessement, i.e. decreasing water quality and vulnerability to landslides or floods. However, the ability of web-GIS technology to help the management of watershed area in Bengkulu is still unknown. Here, we showed how the process of Web GIS development for managing the watershade in Bengkulu could be achived. This study mapped the 2018 land cover area of Rindu Hati Sub-watershed by utilizing Landsat 8 satellite images using the Maximum Likelihood method. The land cover map was then processed and displayed using webGIS media. The results showed that the system accuracy for ground truth land use model result was 77.4% which could be accepted as a good result. Further assessment of pixel validation could be one of the future research. We anticipated that the results could be a starting point for more sophisticated area cover of Sumatra and Indonesia. Furthermore, this could be a major development on knowledge discovery in environment and ecology.

An electronic herbarium published on the Internet allows greater access to the data collected by scientific herbarium for a wide range of users, and also provides remote operation from the herbarium materials. This article analyzes the open source software use to create web mapping service of an electronic herbarium. This article describes the requirements for the functionality of the software for creating web mapping service of electronic herbarium. The article gives a brief description and presents comparative characteristics of free web mapping servers MapServer, GeoServer, GeoMixer, QGIS Server, describes their advantages and disadvantages. The adaptation and conversion of an existing electronic database of Herbarium of the Buryat state University from excel format to vector format has been realized.Comparative analysis has shown that all four web mapping servers (MapServer, GeoServer, GeoMixer, QGIS Server) have sufficient functionality to create on their basis a web mapping service of electronic herbarium, but with some restrictions on certain parameters. A test version of web mapping service of electronic herbarium of the Buryat State University has been created based on UMN MapServer in conjunction with P.mapper.At the moment, the web mapping service includes the following layers: wms-layer of basic map, vector layer reflecting the place of collection of herbarium specimens and their characteristics, vector layer of districts’ boundaries of the Republic of Buryatia.

Analysis and synthesis of domestic and global trends in the development of methods of geoinformation mapping presents that the ever growing need for spatial information in various spheres of modern society, the use of modern access technologies and the transfer of spatial information, determine the transitional stage of the development of cartography to “mapping based on geoinformation resources”. A great demand for spatial information contributes to the creating and using of a large number of network information resources that provide mapping tasks. These network information resources are the main condition for using modern geo-information technologies for solving scientific and practical problems.Mapping based on geo-information resources allows one to expand the range of using heterogeneous spatial data, to increase the audience and shorten the way to the end user when presenting cartographic materials and improve the efficiency of working with cartographic materials due to the technologies of graphical representation of information and control of the content of the resource [Lurye I., Alyautdinov A., Osokin C., 2013]. The development and use of geo-information resources are aimed at creating a uniform information space, as the most effective tool for researching the natural environment and its management.The paper describes the technology of development of the information-retrieval system “Absolute dates of alluvial deposits”, realized as a geo-information resource. Using network technologies allows providing access to the system resources for all interested users. The relational database of spatial data is used as a basic element of the developed information and retrieval system. Spatial database is a set of separate tables linked by logical links of different relations. Much attention has been paid to the creation of a cartographic service which allows displaying and classifying information as well as using the spatial query tool and different cartographic bases, including remote sensing materials.

The effective implementation of preventive conservation approaches demands the employment of standardized and robust tools able to integrate the data coming from multiple sources, inspection and diagnosis techniques, as well as to ensure the proper information transfer between expert and non-expert users. Aiming to make a step forward in the state of the art of current conservation approaches, a cutting edge Web-GIS technology resorting to the intuitiveness of 360° panoramas and 3D point clouds in combination with the Internet of Things is presented in this work, demonstrating how physical and digital worlds can be linked for proper documentation and management of cultural heritage. To validate such a pioneering approach, one of the most representative and complex heritage buildings of Spain is used as a case study: the General Historical Library of Salamanca., This work was financed by ERDF funds through the V Sudoe Interreg program within the framework of the HeritageCare project (Ref. SOE1/P5/P0258), by project Patrimonio 5.0 (SA075P17), by FEDER funds through the Competitive Factors Operational Program (COMPETE) and by the Foundation for Science and Technology (FCT) within the scope of projects POCI-01-0145-FEDER-007633. The authors would like to express their gratitude to the personnel from the General Historical Library of the University of Salamanca as well as to the Centre for Computer Graphics of the University of Minho for the web implementation of the platform.

Geotourism represents a powerful and new form of sustainable tourism that has rapidly expanded worldwide over the last decades. To promote it, the use of digital and geomatic tools is becoming of increasing importance. Especially mobile information represents one of the most efficient and smart ways to bring geotourism closer to a wide audience. This applies in particular to rural and inner areas, where the exploitation of geoheritage can represent a crucial resource for eco-friendly and sustainable tourism development. With the aim to promote geotourism on a regional scale, we have implemented a mobile devise application for Molise region, tested in the Alto Molise area. This application, called MoGeo App, aims at providing diversified geotourism information that combines geologic attractions (geosites and geologic itineraries) with other possible tourist attractions (other sites of natural and cultural interest), to respond to differentiated interests and needs of a wide audience. Besides geotourism purposes, the structure of MoGeo App can be used also for other purposes such as educational targets, by adapting contents and language. It appears to be a flexible, easily updatable digital tool, adaptable to various target groups, as well as other regional contexts, both inside and outside of Italy.

Web-based planetary image dissemination platforms usually show outline coverage of available data and offer querying for metadata as well as preview and download. While the usual form of presenting multiorbit data sets is to merge the data into a larger mosaic, for change detection purposes it is essential to maintain the individual images as an important snapshot of the planetary surface taken at a specific time. We introduce the web-based interactive Mars Analysis and Research System (iMARS web-GIS), which is specialized on planetary surface change analysis with novel tools for simultaneous visualization of single images as time series in their original sequence. As the data foundation, we use the vast quantity of automatically coregistered orthoimages and digital terrain models (DTM) from three NASA missions' instruments processed and ingested in the context of the EU-funded iMars project. The baseline for the coregistered images are the High-Resolution Stereo Camera (HRSC) multiorbit quadrangle image mosaics, which are based on bundle block-adjusted multiorbit DTM mosaics. Additionally, we make use of the existing along-track bundle-adjusted HRSC single images and DTMs available at the planetary data archives. We provide two science cases for exemplary workflows of the multitemporal single-image analysis, demonstrating the dedicated tools for surface change interpretation-one near Mawrth Vallis and one near the south pole. A web mapping application including the presented functionality has been implemented and is available at http://imars.planet.fu-berlin.de with the iMars project website (http://www.i-mars.eu/web-gis) serving as a mirror.

Approximately 20,000 ha of densely built-up areas still remain in Japan. However, the advance of improvements in these areas has been very slow. Thus, making draft improvement plans through citizen–administration partnerships is indispensable to promote improvements. The planning support tool proposed in this study supports a consensus-building process during the creation of draft improvement plans. We develop a disaster mitigation performance evaluation method (DMPEM) for built-up areas at the district level and incorporate this method into a disaster mitigation support Web-GIS. However, DMPEM requires lengthy calculation time because it uses the probabilistic Monte Carlo computation method. Using this tool in real-time planning is therefore difficult. In this study, we first develop a system that reduces the calculation time required by DMPEM. Second, the support tool is used to make draft plans through citizen–administration partnerships in districts where residents are conducting various disaster mitigation activities. Finally, we investigate the usefulness of the tool for consensus building through the promotion of lively discussions among residents and clarify the issues associated with practical use of the tool.

One of the key areas of Web geotechnology development is the implementation of software tools and systems, which are capable not only to display geospatial data in the Web interface, but also to provide functionality for processing and analysis directly in the browser window. Significant feature of current Web-based geo-spatial standards is the focusing on server-side data processing. Our study investigates possibilities and general ways of decentralized data processing implementation on the client side in the case of using the Java Web Start technology. The test software tools are developed that implements capability of transmitting the executable program code to the client computer through the Web interface and spatial data processing on the client side.

The rapid increase in applications of Light Detection and Ranging (LiDAR) scanners, followed by the development of various methods that are dedicated for survey data processing, visualization, and dissemination constituted the need of new open standards for storage and online distribution of collected three-dimensional data. However, over a decade of research in the area has resulted in a number of incompatible solutions that offer their own ways of disseminating results of LiDAR surveys (be it point clouds or reconstructed three-dimensional (3D) models) over the web. The article presents a unified system for remote processing, storage, visualization, and dissemination of 3D LiDAR survey data, including 3D model reconstruction. It is built with the use of open source technologies and employs open standards, such as 3D Tiles, LASer (LAS), and Object (OBJ) for data distribution. The system has been deployed for automatic organization, processing, and dissemination of LiDAR surveys that were performed in the city of Gdansk. The performance of the system has been measured using a selection of LiDAR datasets of various sizes. The system has shown to considerably simplify the process of data organization and integration, while also delivering tools for easy discovery, inspection, and acquisition of desired datasets.

Remote sensing technology and mobile devices are two data collection approaches that are proving invaluable in the disaster response phase of the hazard event. The adoption of these approaches is not universal and still faces significant challenges. The user community must understand the technology, learn how to acquire it, and be trained on its use before the disaster event. Much has been written about volunteered, unvolunteered, and crowd-sourcing of geospatial information for disaster response and recovery. While research in these areas continues, most U.S. federal and state agencies rely on authoritative data collected by authorized personnel. This research focuses on the use of geospatial technology with mobile devices by appointed users—those individuals with authorization to collect geospatial information for a governmental agency with authority in the disaster response process. This chapter describes a project to develop a web-app that allows appointed users to collect geospatial data in the field with Google Maps and user-supplied imagery and with pre-defined and user-defined structured forms. Although the original purpose focused on disaster response and recovery activities, such as the Urban Search and Rescue (USaR) house-to-house searches, the user-groups, purposes, and technologies rapidly changed in this two year project. Technology for the web environment rapidly changes, particularly for mobile devices. Our focus on the USaR teams changed to all parishes in the state of Louisiana. This project used an agile software development approach, which permitted the evolving nature of the user requirements. Without this agile approach the user community would not have adopted the application for emergency response.

In recent years, GIS systems have evolved because of technological advancements that make possible the simultaneous management of multiple amount of information.Interesting aspects in their application concern the site documentation at the territorial scale taking advantage of CAD/BIM systems, usually working at the building scale instead.In this sense, the survey using sophisticated equipment such as laser scanners or UAV drones quickly captures data that can be enjoyed across even through new “mobile” technologies, operating in the web-based information systems context. This paper aims to investigate use and perspectives pertaining to geographic information technologies, analysis and design tools meant for modeling at different scales, referring to results of research experiences conducted at the University of Bologna., I sistemi GIS si sono evoluti negli ultimi anni in ragione di avanzamenti tecnologici che consentono la gestione contemporanea di molteplici quantità di dati informativi. Aspetti interessanti nella loro applicazione riguardano la documentazione alla scala territoriale con i sistemi di modellazione CAD/BIM, operanti solitamente alla scala edilizia. In tal senso, il rilievo con apparati sofisticati come i laser scanner o i droni UAV consente di acquisire speditivamente dati che possono essere fruiti trasversalmente anche attraverso le nuove tecnologie di comunicazione “mobili”, capaci di operare nell’ambito di sistemi informativi basati sul web. Il presente contributo ha l’obiettivo di indagare l’uso attuale e le prospettive delle tecnologie dell’informazione geografica, nell’analisi e nella modellazione progettuale alle diverse scale, sulla base di esiti di esperienze di ricerca condotte presso l’Università di Bologna., DISEGNARECON; Vol. 6, n. 11 (2013) - GIS & Disegno urbano, a cura di Roberto Mingucci e Ana Clara Mourão Moura; 11 - 20

Empirical data can be characterized by a precise location in space and time. An estimated 80% of all data holds such a spatio-temporal reference and is termed geodata. This paper starts with the question: What is the additional benefit for socio-economic sciences using geodata and the spatial dimension respectively? In the following a multidimensional approach is chosen to outline the Status Quo of geodata and spatial techniques in Germany. It is particularly the continuously growing amount and the variety of available geodata which is stated. Data security is an issue of high importance when using geodata. Furthermore, the present developments in price and user concepts, accessibility, technical standards and institutionalisation are addressed. A number of challenges concerning the field of geodata are identified including the open access to geodata, data security issues and standardization. The main challenge however seems to be the exchange between the rather segregated fields of geoinformation and the information infrastructure. Furthermore, the census 2011 is identified as a major challenge for the acquisition and management of geodata. Geodata and spatial techniques are a rapidly developing field due to technology developments of data and methods as well as due to recently growing public interest. Their additional be efit for socioeconomic research should be exploited in the future.

Tez (Doktora) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2008, Thesis (PhD) -- İstanbul Technical University, Institute of Science and Technology, 2008, Yerkabuğu deformasyonu çalışmaları, tekrarlı jeodezik ölçmelerin analizi ve bunların jeolojik ve jeofizik araştırmalardan elde edilen sonuçlar ile birlikte değerlendirilmesine dayanır. Bir disiplinin ürettiği sonuç, diğer bir disiplinin girdi verisi olduğundan, tek tip veri üreten bir çalışmanın, diğer çalışmalardan üretilmiş değişik tipteki verileri kendi verisi ile entegre etmediği sürece anlamlı bilgi üretemeceği açıktır. Bu da göstermektedir ki, çözülmesi gereken problem doğal olarak disiplinlerarası bir karaktere sahiptir. Ancak yer bilimciler genellikle problemin bir yanı üzerine çalışmakta ve sadece istendiğinde verisini paylaşma eğilimindedirler. Bu nedenle kaynaklar, tekrar tekrar aynı çalışmalar üzerinde boşuna harcanmış olmaktadır. Halbuki günümüzde verinin mümkün olduğu kadar çabuk ve efektif olarak bilgiye dönüşmesi gerekmektedir. Bunu gerçekleştirebilmek için hesap ve analiz ortamlarının araştırmacıların, karar vericilerin ve eğitimcilerin masaüstü bilgisayarlarına taşınmış olması gerekmektedir. Bu çalışmanın amacı, çok disiplinli yer bilimleri verilerini, araçlarını ve yazılımlarını birbirine bağlayan ve paylaşımını sağlayan servis odaklı mimari yapıda bir Coğrafi Bilgi Sisteminin oluşturulması ve bu sisteme farklı seviyelerde kullanıcıların (bilimadamı, eğitimci, karar verici vd.) ulaşımının sağlanması ve böylece Türkiye’de depremler ile ilgili çalışma yapmak isteyenlerin, kolay kullanım arayüzü ile interaktif olarak veriye, hesap ve analiz ortamına ulaşmasının sağlanmasıdır., The studies of recent crustal movements are based on analyses of repeated geodetic measurements, and their combination with results of geophysical and geological investigations. It is obvious that a single data producer can not produce useful datasets and information without integrating data from others because one scientist’s results become another’s data. So, the problem to be solved naturally has an interdisciplinary character. However, Earth scientists traditionally work on one aspect of the problem and they have a tradition of sharing of data but they are willing to share it if asked. Because of this, the resources are being wasted in duplicative efforts. However, the goal is for data to evolve it into information, and then into knowledge as quickly and effectively as possible. In order to do this, calculations and analysis need to bring to the desktops of researchers, decision-makers, and educators. The aim of this study is to develop a service oriented architecture based Geographic Information System (GIS) that enables linking and sharing multidisciplinary Earth science data, tools, and software and to provide a wide range of users (scientist, educators, policymakers, etc.) access to the system and in this way to build an easy-to-use interactive access to data and analysis environment to study earthquakes in Turkey., Doktora, PhD

This paper describes a framework of methods for the measurement and evaluation of users’ performance in interaction with a web-GIS. The framework involves testing of a system with real-world users, streaming of the user’s screen during the evaluation and the analysis of web-server log files after the evaluation. We have developed and tested this method within a project called RIV together with real-world users that are using a web-GIS. We found out that users have different strategies when interacting with a web-GIS that offers different manners of interaction. The findings that we present in this paper are useful for developers and designers of web-GIS and can help improving such systems.
