ProtoMaps is a [[BSD-3]] map providing tools that combines [[OpenStreetMap]] with other data sources into a simple, deployable application. Written in [[Javascript]] with [[Go]] and [[Java]] tools. - [Website](https://protomaps.com/) - [Source](https://github.com/protomaps) - [Documentation](https://docs.protomaps.com/basemaps/downloads) # Notability Offline maps are useful. # Philosophy ## Licensing Originally ProtoMaps was partially open, with standards in the public domain, some core components as [[BSD-3]] licensed, and others proprietary. In 2024, ProtoMaps transitioned to fully open source under the [[BSD-3]] license.[^1] # Tips ## Partial Downloads The full set of map data is over 120Gb, so it can be more convenient to only keep what you need. - https://docs.protomaps.com/pmtiles/cli#extract # Resources Terrain mapping recommended by ProtoMaps: https://mapterhorn.com/ # References [^1]: https://protomaps.com/blog/open-core-to-open-source/
