Interoperability ERRA System

Introduction PPRD East Project The overall objectives of the PPRD East project are: To contribute to the development of the Partner Countries‘ civil protection capacities for disaster prevention, preparedness and response; To bring the Partner Countries progressively closer to the EU Civil Protection Mechanism and improve cooperation among them.

Definitions Geoportal: «Web site that provides a view into a universe of spatial content and activity through a variety of links to other sites, communication and collaboration tools, and special features geared toward the community served by the portal.» (OGC 2012) Spatial data infrastructure (SDI) 1: «computerised environment for handling data that relate to a position on or near the surface of the earth » (CEN/TR 15449:2011) Spatial data infrastructure (SDI) 2: “the metadata, spatial data sets and spatial data services; network services and technologies; agreements on sharing, access and use; coordination and monitoring mechanisms, processes and procedures, established, operated or made available in an interoperable manner.” (INSPIRE, European Parliament 2007).

Definitions Interoperability: «capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units» Interoperability: « within the context of European public service delivery, is the ability of disparate and diverse organizations to interact towards mutually beneficial and agreed common goals, involving the sharing of information and knowledge between the organizations, through the business processes they support, by means of the exchange of data between their respective ICT systems. »

Interoperability Goals Interoperability addresses the need for: cooperation among public administrations with the aim to establish public services; exchanging information among public administrations to fullfil legal requirements or political commitments; sharing and reusing information among public administrations to increase administrative efficiency and cut red tape for citizens and businesses. The result is: improved public service delivery to citizens and businesses by facilitating the one-stop-shop delivery of public services; lower costs for public administrations, businesses and citizens due to the efficient delivery of public services.

Interoperability Levels

Evolution Compatibility De facto standard Interoperability Interoperability relies on Common Standard Specifications Agreements

Geospatial Interoperability using OGC Web Services Freedom to combine and integrate components of an information system Open Standards Exchangeable across different application/platforms Open Geospatial Consortium (OGC) Consortium of GIS vendors, government agencies, academic institutions and private entities Proposing standard and specifications for geospatial Interoperability (data format, protcol, definition of map projection, metadata… etc)

OGC Standards Source: Wikipedia

OGC Standards Source: Wikipedia Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database. Web Coverage Service (WCS) defines Web-based retrieval of coverages – that is, digital geospatial information representing space/time-varying phenomena. Web Feature Service (WFS) provides an interface allowing requests for geographical features across the web using platform-independent calls

OGC Web Services (OWS) The geospatial web is enabled by OGC standards: Web Map Server Web Coverage Web Feature Web Map Service (WMS) Web Map Tile Service (WMTS) Web Feature Service (WFS) Web Coverage Service (WCS) Catalogue (CSW) Geography Markup Language (GML) KML Others… Relevant to geospatial applications: Critical Infrastructure, Emergency Management, Weather, Climate, Homeland Security, Defense & Intelligence, Oceans Science, etc
