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.

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 GoalsInteroperability 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

EvolutionCompatibility 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)

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
