At MapTiler, we believe in open-source projects and actively contribute to several key ones in the geospatial industry. This means we are always keen to participate in the annual FOSS4G event, so we can share ideas and hear about the latest developments. This year our team traveled to Prizren in Kosovo to meet with collaborators & friends and help shape the future of open-source geospatial software. We gave talks about our SDK, MapTiler Engine, and OpenMapTiles, and a very well-attended talk about cartography for web maps.
