System architecture. A request for KML file is submitted by the client to the server. The MySQL database tier contains a subset table of the GeoNet Names, population and immunization data. Processing of the request involves querying the database to extract latitude and longitude data (case based mapping) or other required information (choropleth maps) and assembling the final KML. The final formatted KML file is returned to the client and is loaded in the viewer.
