OpenStreetMap (OSM), often called the "Wikipedia of maps," is a powerful tool for knowledge sharing, community engagement, and open data collaboration. This session will explore how OSM contributes to inclusivity by making geographic data accessible to all, supports impactful projects such as disaster response and local development, and promotes sustainability through open and community-driven mapping efforts. Participants will learn how OSM complements Wikimedia projects like Wikidata and Wikipedia, empowering communities to document their environments and preserve local knowledge. Through real-world examples, we will highlight how mapping can bridge knowledge gaps, enhance representation, and create lasting social change. Whether you're a beginner or an experienced Wikimedian, join us to discover how you can contribute to a more inclusive and sustainable world through open mapping.
