Charities can benefit greatly from web GIS because of the unique ability to measure impact they have in communities they serve, with their stakeholders and potential donors through web maps. The Trailblazer Foundation has been working in Siem Reap, Cambodia, one of the poorest provinces in Cambodia, for nearly a decade. They primarily install bio-sand water filters, in addition to other sustainable community development projects in areas of greatest need. The web mapping application built for this project allows the Trailblazer Foundation to analyze its impact in Siem Reap and share results, all in a web-based environment. Spatial analysis was conducted to compare living conditions of project beneficiaries over time, and compare to results throughout the province as well as identify areas within Siem Reap that require more attention as a result of significantly poorer living conditions measured by survey results. The interactive application allows stakeholders with little to no GIS experience to explore the data and inform themselves of the difference Trailblazer Foundation has made in the lives of rural Cambodians. This project is an example of how GIS can improve lives by identifying areas of greatest need and connecting those communities with the resources that enable healthier lives.
