ECDC overview


The European Centre for Disease Prevention and Control (ECDC), is the

European Union agency with the responsibility of strengthening EU defences

against infectious diseases.

ECDC's mission:

To identify, assess & communicate

current & emerging threats to

human health posed by infectious

diseases.

To support and help to coordinate

EU countries’ preparedness and

response capacities.

Agenda


•ECDC overview






ECDC identified GIS as a powerful tool, both for tasks within ECDC & to

present information to its external partners with the aim of strengthening

Europe’s defence against infectious diseases.

Objective:

1.Improve current disease mapping capabilities.

2.Support a plethora of tasks and processes within Units where there is a

need for a GIS component.

Origins of GIS project at ECDC, I


Origins of GIS project at ECDC, II

1. Elaboration of a GIS needs Assessment Report.

2. Creation of a European Environment and Epidemiology (E3) Network.

3. Allocation of budget to support the future Enterprise GIS development work.

Why an Enterprise GIS?

This GIS solution did not allow to get access to timely, accurate &

guaranteed geospatial information.

ECDC had a GIS departmental structure that served the needs of the

particular sections/teams, instead of the entire organization as an entity


Benefits of having an Enterprise GIS?

Having a robust, integrated GIS system that meets organization needs

Encourage to use a common infrastructure thorough the organization

Share the geospatial information available within the organization

Provide accessibility to a common geospatial data repository

Existence of a single source for maps

Promote the use of standardized geospatial data, tools and services.


ECDC Mapping & Multilayer Analysis (EMMA)

Started in May 2011

Took over the recommendations included in the GIS Needs Assessment report (June 2010)

Was planned as a centralized GIS platform to support disease mapping, dataanalysis & data sharing among ECDC experts & to extranet public, which willfacilitate the communication on public health threats

This system will contribute to the compilation of standardized spatial data

Its implementation will be supported by the establishment of internal SOPs.

Conclussions

GIS technology:

Supports a wide diversity of working areas at ECDC

Contributes to the development of geospatial standards for disease data

Helps to better identify disease patterns

Allows sharing of geo-information using a common platform

Represents an unifying role: Integrates different objectives, projects &

expertises within the organization

Plays an essential role in communicating information related to public health.
