There is increasing recognition of the value of Geographic Information Systems (GIS) in Public Health at national, European and international levels. There have been important new developments in methodologies in relation to GIS and spatial analyses, but to fully exploit these new methods within the applications field, they need to be utilised by mainstream public health researchers with a clear and detailed insight into current important issues in the public health field. The aim of this conference is to promote the sharing of experiences and exchange of ideas on the role of geographic information sciences in public health across Europe, bridging the gap between the methodological developments field and the public health research applications field. The focus will revolve around geographic surveillance in public health, encompassing 4 elements of public health: communicable disease and environmental health; health needs and health impact assessment; planning and implementation of interventions; monitoring and evaluation. The conference will bring together people from many different fields in the broad area of public health and will be the first European conference on this important aspect of public health.
