The Geospatial devroom is the place to talk about the state of the art of open, geo-related data, free and open source geospatial software and its ecosystem. This includes standards and tools, e.g. spatial databases, online mapping tools, geospatial services, used for collecting, storing, delivering, analysing, and visualizing geodata.
