Sourcemap is a interactive web portal for visualization of global supply chains and product origins. Based on the fundamental idea that people have a right to know about the the origins and composition of the things they use and consume, Sourcemap provides a platform for researching, optimizing and sharing the supply chains behind a number of everyday products. I contributed to Sourcemap as a designer and researcher, specifically on extending the original version of Sourcemap to mapping the origins and composition of food products. Working with chefs, caterers, restaurateurs, and workers across the food industry to understand how a platform like Sourcemap could facilitate their interactions with people and products, I designed a layout for the portal extended for the needs of the food industry. I also designed a series of mockups for integrating Sourcemaps into professional catering and restaurant menus.
