Geospatial information, a key element to strength Europe’s Defences against infectious diseases: the ECDC experience

• Future development plans tocreate a centralized GISplatform

The European Centre for Disease Prevention and Control (ECDC), is the European Union agency with the responsibility to strengthen Europe's defences against infectious diseases.

Mission

To identify, assess and

communicate current and

emerging threats to human

Health posed by infectious

diseases, and to support and

help coordinate European Union

countries’ preparedness and

response capacities.

GIS Team

Current geospatial information available and context in which it is used

Before creation of GIS team

• ESRI datasets (VMAP0): Admin. boundaries, hydrographic network…

• Population data from EUROSTAT

• Other datasets disperse: Raster/Vector/Tables

• Environmental datasets from the European Environment &

Epidemiology (E3) network

After creation of GIS team

• Acquisition of NUTS 0, 1, 2, 3

• GAUL data (0,1,2)

• In process to collect geo-reference health data

• In process to collect a good repository of raster/

vector maps worldwide

• Some specific datasets from GISCO geodatabase

Enterprise GIS for ECDC

Based on:

1. GIS Needs Assessment Report produced in June 2010

2. Centralized GIS platform that will support disease mapping,

data analysis and data sharing among ECDC experts and

The future ….

data analysis and data sharing among ECDC experts and

potentially to extranet public

3. Compilation of standardized spatial data

Development of Analytical Functions

& Geoportal Capabilities

• Rapid & friendly web application

• Inclusion of an entry data module to facilitate mapping work

• Update & edit event data

• Elaboration of two types of maps: choropleth

• Customized data classification

• Provision of standard GIS tools

New projects

• Creation of specific mapping environments

• Development of a mapping interface within their

2nd Phase: Integration with Internal Systems

own environments

• Inclusion of specific data entry modules to

facilitate mapping work

• Establishment of map services

Analytical functionalities, Geoportal capabilities Harmonization of all GIS modules

• Development of spatial analysis techniques: Buffering, cluster detection, etc.

• Development of Geoportal functionalities: drag & drop of selected datasets,

elaborated maps, map templates,

metadata files visualization & editing, etc.

• Integration of all mapping applications &

functionalities within a common platform

Conclusions

Spatial information combined with GIS within Public Health:

• Allows managing emergencies: risk assessments, monitoring outbreaks, etc...

• Contributes to achieving public health objectives

• Plays an essential role in publich health communication

• Provides scientific evidence

Spatial information at ECDC:

• Can be used within a wide diversity of areas: from emergencies to long term

predictions

• Provides timely information

• Is a cost effective resource

• Plays a unifying role: Integrates different objectives, projects & expertises

within the organization
