Designing Web-enabled services to provide damage estimation maps caused by natural hazards

The availability of building stock inventory data and demographic information is an important requirement for risk assessment studies when attempting to predict and estimate losses due to natural hazards such as earthquakes, storms, floods or tsunamis. The better this information is provided, the more accurate are predictions on damage to structures and lifelines and the better can expected impacts on the population be estimated. When a disaster strikes, a map is often one of the first requirements for answering questions related to location, casualties and damage zones caused by the event. Maps of appropriate scale that represent relative and absolute damage distributions may be of great importance for rescuing lives and properties, and for providing relief. However, this type of maps is often difficult to obtain during the first hours or even days after the occurrence of a natural disaster. The Open Geospatial Consortium Web Services (OWS) Specifications enable access to datasets and services using shared, distributed and interoperable environments through web-enabled services. In this paper we propose the use of OWS in view of these advantages as a possible solution for issues related to suitable dataset acquisition for risk assessment studies. The design of web-enabled services was carried out using the municipality of Managua (Nicaragua) and the development of damage and loss estimation maps caused by earthquakes as a first case study. Four organizations located in different places are involved in this proposal and connected through web services, each one with a specific role

The PREVIEW Global Risk Data Platform: a geoportal to serve and share global data on risk to natural hazards

With growing world population and concentration in urban and coastal areas, the exposure to natural hazards is increasing and results in higher risk of human and economic losses. Improving the identification of areas, population and assets potentially exposed to natural hazards is essential to reduce the consequences of such events. Disaster risk is a function of hazard, exposure and vulnerability. Modelling risk at the global level requires accessing and processing a large number of data, from numerous collaborating centres. <br><br> These data need to be easily updated, and there is a need for centralizing access to this information as well as simplifying its use for non GIS specialists. The Hyogo Framework for Action provides the mandate for data sharing, so that governments and international development agencies can take appropriate decision for disaster risk reduction. <br><br> Timely access and easy integration of geospatial data are essential to support efforts in Disaster Risk Reduction. However various issues in data availability, accessibility and integration limit the use of such data. In consequence, a framework that facilitate sharing and exchange of geospatial data on natural hazards should improve decision-making process. The PREVIEW Global Risk Data Platform is a highly interactive web-based GIS portal supported by a Spatial Data Infrastructure that offers free and interoperable access to more than 60 global data sets on nine types of natural hazards (tropical cyclones and related storm surges, drought, earthquakes, biomass fires, floods, landslides, tsunamis and volcanic eruptions) and related exposure and risk. This application portrays an easy-to-use online interactive mapping interface so that users can easily work with it and seamlessly integrate data in their own data flow using fully compliant OGC Web Services (OWS)

A multidisciplinary Spatial Data Infrastructure for the Mediterranean to support implementation of the Marine Strategy Framework Directive

29 páginas, 4 figuras, 2 tablas, 1 apéndice.The Marine Strategy Framework Directive (MSFD) adopted in 2008 aims to protect the marine environment through the holistic Ecosystem Approach (EA). The MSFD requires Member States to develop and implement cost-effective measures to achieve and/or maintain “Good Environmental Status” (GEnS). To this end, interested parties require a large amount of data and this data should be appropriately managed. This is particularly true for EA applications, where data can come from diverse sources, in diverse formats, and from several disciplines. Preliminary steps for supporting reliable multi-disciplinary analysis include data collection, data management, and the implementation of an interoperable sharing system. In an effort to implement this type of multidisciplinary analysis, a working group from the KnowSeas project (www.knowseas.com) created a Spatial Data Infrastructure for the Mediterranean Sea, designed to define and analyze the GEnS concept across various geographical scales. This article describes the implementation of this SDI, demonstrating how an interoperable system can provide strong support in implementing the MSFD under the EA, and how marine spatial planning can assist policymakers in the decision making process.This work was co-funded by the KnowSeas project (grant number 226675) and the EGIDA project (grant number 265124).Peer reviewe

European Union Location Framework - Guidelines for public procurement of geospatial technologies

These guidelines focus on the procurement of location information products and services, such as the acquisition of new location data to support applications, the acquisition of solutions for using location data and services in e Government processes and products and/or services for making data interoperable and/or accessible. The procurement can take place as part of the development of a Spatial Data Infrastructure (SDI), the implementation of the INSPIRE regulation, or any other Directive in which such information and services are important, or within the context of regular activities of spatial data and service providers and users (e.g. Mapping and Cadastre Agencies, Government departments, local public administrations). The guidelines provide recommendations on elements of best practice in procurement in which location information and location enabled services are important, with some practical examples; and describe some concrete sample texts that could be used in invitations to tender when reference is made to location information and location enabled service requirements. The procurement process is also explained as part of a potential future e-procurement platform in which the application and updating of geospatial standards (through change requests) could be integrated as well.JRC.H.6-Digital Earth and Reference Dat

Building bridges: experiences and lessons learned from the implementation of INSPIRE and e-reporting of air quality data in Europe

The collection, exchange and use of air quality data require diverse monitoring, processing and dissemination systems to work together. They should supply data, which can afterwards be used in different contexts such as planning, population exposure and environmental impact assessment. As air quality is not dependant on national borders this would only be feasible on an international level. This manuscript reports on the lessons learned from using the world’s largest data harmonization effort for environmental information infrastructure - INSPIRE as a backbone of a European wide spatial data reporting system which involves an unprecedented number of actors and volumes of data. It is important in the context of Digital Earth, and the establishment of a global SDI through the Global Earth Observation System of Systems (GEOSS), as the quality of ambient air is among the pressing environmental problems of today. We summarize our findings from the perspective of national public authorities, obliged by law to transmit spatio-temporal data in order to streamline reporting and facilitate the use of information, while keeping public expenditure at minimum. To identify what works in this type of reporting we established a cross-border case study, looking at the process of harmonization and exchange of data in Belgium and the Netherlands based on interoperable standards. Our results cover the legal, semantic, technological and organizational aspects of reporting. They are relevant to a cross-thematic audience, having to undergo similar processes of reporting, such as climate change, but also environmental noise, marine, biodiversity, and water management.JRC.H.6-Digital Earth and Reference Dat
