FOSS4G 2023 Prizren Protomaps is a simple, self-hostable system for tiled vector datasets. In the year since last FOSS4G, we've rolled out a new compressed specification (V3), added support for tile generation tools, and open sourced key integrations with content delivery networks. This talk will give an overview of: - Why you might want to, or not want to, deploy Protomaps for your application - PMTiles write support in the popular Tippecanoe and Planetiler tools - The new open source integrations of Protomaps with AWS Lambda and Cloudflare - Overview of real-world deployments for users in web GIS, journalism and the public sector
