The American Red Cross International Services Department (ISD) and project partners are developing a web visualization tool (Mapfolio) to help to visualize Red Cross's disaster response and humanitarian projects around the world. The solution uses innovative Node.js ETL processing to process information from the Red Cross Salesforce Information Management platform. The Mapfolio is open source built on Node.js, Angular, Leaflet, PostGIS, and a custom PGRestAPI (Chubbs). Other technical advances include a custom Leaflet clipped-polygon labeling as well as a map-view-dependent (not zoom level dependent) display of global administrative boundaries. This session will not only walk through the open source components but will also focus on how the Red Cross defined clear deliverables and scaled-up its support of free and open source software.
