About GAIA

GAIA is an information-based visualization tool designed to provide the capability of creating meaningful, interactive geospatial representations of public health and epidemiological data. Data of this nature, whether gathered through collection, surveys or simulation, may be complicated. Many try to represent such data in the form of tables and aggregated charts. Such approaches are quite laborious to read through quickly and remove necessary quantitative detail from the data. The goal of the GAIA software is to translate the complicated data to a geographic representation and allow users the ability to navigate down to any level of the data that is desired. GAIA provides visualizations that are more than just qualitative in nature, but also enable an exploration of the quantitative data in an intuitive and unique manner, making it a truly useful tool beyond the “creating pretty picture” aspects of many visualization packages.& Examples of the use of GAIA include:

  1. Apollo: Project for creating a common ontology and framework for epidemic modeling
  2. FRED: Framework for Reconstruction of Epidemic Dynamics
  3. Tycho: Open Access Database of United States Disease Data
  4. PHASYS: The University of Pittsburgh CDC Funded Public Health Adaptive Systems Study.
