Abstract

A Spatial Analysis System for Environmental Health Surveillance
Track: Education
Authors: Chetan Tiwari

Disparate and spatially incompatible datasets, methods and models for mapping environmental risks and health outcomes pose a hurdle for environmental health surveillance activities. We present an extensible, web-based spatial analysis system that integrates these diverse aspects of environmental health surveillance using GIS methods and software services that can be delivered over secure computer networks. The Environmental Health Surveillance System (EHSS) is a prototype system that is designed to serve three primary purposes: (1) to provide a secure environment for producing maps of disease burdens in a manner that can utilize individual-level health data and provide outputs that protect the privacy of the individuals who were included in the analysis, (2) to demonstrate the ability to automate the process of linking environmental data and models with geocoded locations of individuals, and (3) to visualize the spatial patterns of disease outcomes via web-based mapping interfaces.
