There is a lot of potential locked in spatial data and this potential may be realized by making spatial data readily available for various applications. SD1 （Spatial Data Infrastructures） provides a platform for the data users, producers and so on to generate and share spatial data effectively. Though efforts to develop spatial data infrastructures started worldwide in the late 1970s, SDIs are still perceived by many institutions as new innovation; as such, they have not penetrated to all institutions to bring about effective management and development changes. This paper is reporting on a study conducted to assess SDI Readiness Index for Tanzania. The study aimed at identifying problems undermining SD1 implementation in Tanzania, despite its potential in bringing fast socio-economic development elsewhere in the world. This paper is based on a research based on views from stakeholders of geospatial technology industry in Municipal Councils, Private Companies and Government Departments in Tanzania. Results indicated that Private Companies are more inspired than Government institutions towards implementation of SDIs. And those problems affecting implementation of SDIs are lack of National SDI Policy, lack of awareness and knowledge about SDIs, limited funding to operationalise SDI, lack of institutional leadership to coordinate SDI development activities, lack of political commitment from the Government. It is recommended that delibate efforts be devised to raise awareness of SDI amongst the Tanzanian community.展开更多

Amongst the many challenges left, a thorough analysis of the information flows between existing SDIs as well as their respective uses and the way that those evolve over time is an important issue to explore. The research presented in this paper introduces a methodological framework oriented to the study of the SDIs use from a diachronic perspective. The approach is based on a Social Network Analysis (SNA) and questionnaires collected by online surveys. We develop a structural and diachronic analysis based on a series of graph-based measures identifying the main patterns that appear over time. The methodological framework is applied to a series of French SDIs and users involved in environmental management. The study identifies a series of structural differences in the data flows that emerge between the users and SDIs. Last, the diachronic network analysis provides an overall understanding on how data flows evolve over time at different institutional levels.展开更多

To further this aim, a collaborative, modular, and information and communications technology-based Spatial Data Infrastructure(SDI)called SIRENE—Sistema Informativo per la Preparazione e la Risposta alle Emergenze(Information System for Emergency Preparedness and Response) is designed and implemented to access and share, over the Internet, relevant multisource and distributed geospatial data to support decision makers in reducing disaster risks. SIRENE flexibly searches and retrieves strategic information from local and/or remote repositories to cope with different emergency phases. The system collects, queries, and analyzes geographic information provided voluntarily by observers directly in the field(volunteered geographic information(VGI) reports) to identify potentially critical environmental conditions. SIRENE can visualize and cross-validate institutional and research-based data against VGI reports,as well as provide disaster managers with a decision support system able to suggest the mode and timing of intervention, before and in the aftermath of different types of emergencies, on the basis of the available information and in agreement with the laws in force at the national andregional levels. Testing installations of SIRENE have been deployed in 18 hilly or mountain municipalities(12 located in the Italian Central Alps of northern Italy, and six in the Umbria region of central Italy), which have been affected by natural hazard-induced disasters over the past years(landslides, debris flows, floods, and wildfire) and experienced significant social and economic losses.展开更多

It was implemented to share official geographic information from Alentejo and Extremadura, and now Centro region, with everyone. This is the most effective way to have a distributed and flexible system to be used as a territorial observatory for sustainable development and environment protection in these rural and low populated regions. It also contributes to territorial cohesion, one of the tree main pillars of European Cohesion Policy. It＇s characterized for being a distributed, decentralized, modular and collaborative system, based on standards OGC （Open Geospatial Consortium）, W3C （World Wide Web Consortium）, ISO （International Organization for Standardization） and open source technology, developed to guarantee interoperability between the different GIS （Geographic Information System） provided by each project partner. The geoportal is multilingual （Portuguese, Spanish and English） and integrates a Map viewer, Metadata Catalogue and Gazetteer. It consists in central and local nodes which communicate through WMS （Web Map Services）, CSW （Catalogue Service Web） and WFS （Web Feature Services）. It is now implementing SOS （Sensor Observation Services） and WPS （Web Map Processing）. The geographic information available results of an extensive work of data harmonisation adapted to INSPIRE Directive （D 2007/2/EC, the European Parliament and Council, March 14, 2007）. It integrates basic cartography, socio-economic, territorial and environmental indicators.展开更多

文摘Planning in advance to prepare for and respond to a natural hazard-induced disaster-related emergency is a key action that allows decision makers to mitigate unexpected impacts and potential damage. To further this aim, a collaborative, modular, and information and communications technology-based Spatial Data Infrastructure(SDI)called SIRENE—Sistema Informativo per la Preparazione e la Risposta alle Emergenze(Information System for Emergency Preparedness and Response) is designed and implemented to access and share, over the Internet, relevant multisource and distributed geospatial data to support decision makers in reducing disaster risks. SIRENE flexibly searches and retrieves strategic information from local and/or remote repositories to cope with different emergency phases. The system collects, queries, and analyzes geographic information provided voluntarily by observers directly in the field(volunteered geographic information(VGI) reports) to identify potentially critical environmental conditions. SIRENE can visualize and cross-validate institutional and research-based data against VGI reports,as well as provide disaster managers with a decision support system able to suggest the mode and timing of intervention, before and in the aftermath of different types of emergencies, on the basis of the available information and in agreement with the laws in force at the national andregional levels. Testing installations of SIRENE have been deployed in 18 hilly or mountain municipalities(12 located in the Italian Central Alps of northern Italy, and six in the Umbria region of central Italy), which have been affected by natural hazard-induced disasters over the past years(landslides, debris flows, floods, and wildfire) and experienced significant social and economic losses.

文摘In order to facilitate and coordinate spatial data sharing and exchange,many organisations have developed spatial data infrastructures(SDIs).SDI governance plays a pivotal role in the development and evolution of an SDI,but as SDIs are complex adaptive systems,governing is a challenge.This research therefore proposes a complexity perspective to SDI governance by exploring the use of agent-based modelling to simulate and examine SDI governance interactions.In this agent-based simulation,we examine interactions between SDI stakeholders,data availability and the effects of different governance styles(hierarchical,network and laissez-faire governance)and budget policies.The simulation shows that it is possible to mimic SDI governance dynamics through agent-based modelling.By running different scenarios,it appears that a network approach is more successful compared to a hierarchical or laissez-faire approach.Expert validation shows that overall the results of the simulation are credible and insightful,although improvements can be made to make the model more realistic.With agent-based modelling,SDI governance becomes more tangible and visible,which facilitates discussion and understanding.Agent-based modelling therefore appears to be a helpful new approach in a better understanding of the complexities and dynamics of SDI governance.

文摘As an important facilitator in e-government and society in general,Open SDI merits an assessment of its characteristics and the monitoring of its development.The aim of the study was the proposal of the SDI openness assessment approach based on existing openness assessment frameworks,as well as the presentation of the Polish Spatial Data Infrastructure(PSDI)development towards openness.The results indicated that ten geodetic and cartographic databases fulfilled ten out of eleven criteria of data openness,according to the methodological assumptions,and reached a 3-star level of openness.The need for further development of the infrastructure towards sharing public administration data is recognized,as well as non-governmental data that meet the open data criteria,thus contributing to the openness of the SDI.The proposed assessment method,referenced to a five-level data openness system and providing clear scoring benchmarking for assessing SDI openness,may be used for comparative analysis of SDI openness in different countries,including EU Member States that draw on the experience of the implementation of the INSPIRE Directive.
文摘Federated Research Data Infrastructures aim to provide seamless access to research data along with services to facilitate the researchers in performing their data management tasks.During our research on Open Science(OS),we have built cross-disciplinary federated infrastructures for different types of(open)digital resources:Open Data(OD),Open Educational Resources(OER),and open access documents.In each case,our approach targeted only the resource“metadata”.Based on this experience,we identified some challenges that we had to overcome again and again:lack of(i)harvesters,(ii)common metadata models and(iii)metadata mapping tools.In this paper,we report on the challenges we faced in the federated infrastructure projects we were involved with.We structure the report based on the three challenges listed above.
文摘Many visions for geospatial technology have been advanced over the past half century.Initially researchers saw the handling of geospatial data as the major problem to be overcome.The vision of geographic information systems arose as an early international consensus.Later visions included spatial data infrastructure,Digital Earth,and a nervous system for the planet.With accelerating advances in information technology,a new vision is needed that reflects today’s focus on open and multimodal access,sharing,engagement,the Web,Big Data,artificial intelligence,and data science.We elaborate on the concept of geospatial infrastructure,and argue that it is essential if geospatial technology is to contribute to the solution of problems facing humanity.
文摘The 2030 Agenda for Sustainable Development provides a new global policy to guide the way countries collectively manage and transform the social,economic,and environmental dimensions of people and the planet over the next 15 years.Achieving sustainable development presents all countries and the global policy community with a set of significant development challenges that are almost entirely geographic in nature.Many of the issues impacting sustainable development can be analyzed,modeled,and mapped within a geographic context,which in turn can provide the integrative framework necessary for global collaboration,consensus and evidence-based decision-making.However,and despite significant advances in geospatial information technologies,there is a lack of awareness,understanding and uptake,particular at the policy and decision-making level,of the vital and integrative role of geospatial information and related enabling architectures such as National Spatial Data Infrastructures.This paper reasons that the role of geospatial information in contributing to sustainable development has not adequately been described by either the sustainable development policy practice or by the geospatial professional community.This lack of policy and guidance,with commensurate critical gaps and connection points with national geospatial frameworks,is a visible impediment to developing countries and those most affected by the challenges and need to achieve sustainable development.The global geospatial community now has a unique opportunity to integrate and connect geospatial information into the global development agenda in a more holistic and sustainable manner,specifically in contributing their data resources toward measuring and monitoring the 17 Sustainable Development Goals,and their 169 associated targets,through the global indicator framework that anchors the 2030 Agenda for Sustainable Development.This paper introduces and discusses a new strategic framework for linking a global policy to national geospatial capabilities.

文摘There exist major challenges in accelerating the spatial data infrastructure(SDI)planning process in the developing countries as well as advocating for politicians to support the development of SDI,due to the high complexity of SDI,lack of knowledge and experience,and limited insight in the benefits.To address these challenges,a methodology for SDI planning in Tanzania,based on the system dynamics technique and the communities of practice concept,was adopted and applied within a community consisting of experts from stakeholder organizations.The groups gathered to develop an SDI plan,while they shared their knowledge and discussed their ideas that helped their understanding of SDI.By running the system dynamics model,the development of SDI over time could be simulated that gave the planning community an insight about the future effects of today’s plans and decisions.Finally,an optimum model could be developed by refinements and improvements done with the consensus of the SDI stakeholders.This model included the components and policies that are essential for a successful SDI implementation in Tanzania and can be used as a basis for SDI planning and help to gain political support.Lessons learnt from this research were promising regarding the usability of the methodology for SDI planning in comparable countries.
文摘IDE-OTALEX is the first crossborder spatial data infrastructure between contiguous Portuguese （Alentejo and Centro） and Spanish （Extremadura） regions. It was implemented to share official geographic information from Alentejo and Extremadura, and now Centro region, with everyone. This is the most effective way to have a distributed and flexible system to be used as a territorial observatory for sustainable development and environment protection in these rural and low populated regions. It also contributes to territorial cohesion, one of the tree main pillars of European Cohesion Policy. It＇s characterized for being a distributed, decentralized, modular and collaborative system, based on standards OGC （Open Geospatial Consortium）, W3C （World Wide Web Consortium）, ISO （International Organization for Standardization） and open source technology, developed to guarantee interoperability between the different GIS （Geographic Information System） provided by each project partner. The geoportal is multilingual （Portuguese, Spanish and English） and integrates a Map viewer, Metadata Catalogue and Gazetteer. It consists in central and local nodes which communicate through WMS （Web Map Services）, CSW （Catalogue Service Web） and WFS （Web Feature Services）. It is now implementing SOS （Sensor Observation Services） and WPS （Web Map Processing）. The geographic information available results of an extensive work of data harmonisation adapted to INSPIRE Directive （D 2007/2/EC, the European Parliament and Council, March 14, 2007）. It integrates basic cartography, socio-economic, territorial and environmental indicators.

文摘The world's urban population is soaring,with an increasing number of people exposed to urban natural hazards such as riverinefloods and storm surges.The global quantification of their extent is,however,still blurred.The ongoing surge in high-resolution data allows novel opportunities for quantification of hazards and exposure.Here,we provide a global spatial synthesis of urban populations'exposure to riverinefloods and storm surges in 1990 and 2015.Our results reveal that,owing to rapid economic development globally in a large proportion of exposed areas,most of the exposure has shifted from low-income to middle-income countries.Asia dominates as a continent.The total growth of human exposure continues,suggesting that disaster risk reduction policies and implementation call for enduring effort.
文摘Geothermal data are published using different IT services,formats and content representations,and can refer to both regional and global scale information.Geothermal stakeholders search for information with different aims.E-Infrastructures are collaborative platforms that address this diversity of aims and data representations.In this paper,we present a prototype for a European Geothermal Information Platform that uses INSPIRE recommendations and an e-Infrastructure(D4Science)to collect,aggregate and share data sets from different European data contributors,thus enabling stakeholders to retrieve and process a large amount of data.Our system merges segmented and national realities into one common framework.We demonstrate our approach by describing a platform that collects data from Italian,French,Hungarian,Swiss and Icelandic geothermal data providers.
