Google Earth software and the Google Maps online web site make map data easily available and accessible to others. These useful tools are free and easy-to-use, either as the mapmaker or the map viewer. By using these tools, PSI researchers and programmers are able to view and share information about product and service availability, behavior change communication (BCC) interventions, mobile outreach activities, and many more. This data can help PSI staff make more efficient and informed decisions about health programming and product sales and distribution. As a result, PSI will be able to deliver a greater health impact to the populations it serves.
