OpenStreetMap US

OSMCha is the main OpenStreetMap validation tool. It’s used both by corporate and community mappers. After many years being maintained exclusively by Mapbox, OSMCha is now entering a new phase. As Development Seed has now in its team the developers who shaped OSMCha, it will be dedicating efforts to continue the development of the platform.

In this talk, we will share our vision for the future of OSMCha, the challenges we want to work on and present the roadmap for the next few months.
