Inside Overture Maps

Accurate, interoperable map data is the backbone of everything from navigation apps to emergency response systems. In this episode of Geographical Thinking, host Michelle Brake explores how the Overture Maps Foundation is tackling the biggest challenges in digital mapping - data fragmentation, inconsistent formats, and lack of standardization. Executive Director Marc Prioleau joins the show alongside Esri Canada’s Paul Heersink and Arif Rafiq to share how Overture is building a global, open map dataset that’s clean, current, and community-driven. From persistent feature IDs to monthly quality updates and standardized schemas, Overture is helping GIS professionals and organizations unlock the full potential of spatial data. We’ll also hear how Esri Canada’s contributions through roads and address data are aligning with international best practices, and how transportation agencies can benefit from this shared approach. Whether you’re a map lover, data manager, or transportation planner, this episode offers valuable insights into the future of open, authoritative geospatial data.
