We have made extensive use of Google Earth (http://earth.google.com/) as a mapping option in a decision support system for mosquito-borne dengue under development at Colorado State University through funding provided by the Innovative Vector Control Consortium (http://www.ivcc.com/). Our Dengue Decision Support System uses an open source PostgreSQL database (http://www.postgresql.org/) with a PostGIS extension (http://postgis.refractions.net/).

To facilitate use of Google Earth together with a PostgreSQL database we have developed the Geographic Explorer (GeoX) tool.

GeoX can be used to:

1. create new geographic entities and store them in a PostgreSQL database;
   
   
2. display geographic data in Google Earth;
   
   
3. modify GeoX templates for different view options in Google Earth; and
   
   
4. import existing Google Earth .KML data into a PostgreSQL database.

The GeoX tool was developed by Saul Lozano-Fuentes, David Penhall and Sanika Chitari of Colorado State University.

For feedback or questions on the GeoX tool, please contact Saul Lozano-Fuentes:

Funding to develop GeoX was kindly provided by the Google.org (http://www.google.org/) Fund of the Tides Foundation (http://www.tides.org/).
