OpenStreetMap

OpenStreetMap (https://www.openstreetmap.org/export#map=6/51.324/10.426) is built by a community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world. Planet.osm is the OpenStreetMap data in one file.

OpenStreetMap（https://www.openstreetmap.org/export#map=6/51.324/10.426）乃由一群测绘者共建并维护，其内容涵盖全球范围内的道路、小径、咖啡馆、火车站等诸多地理信息，形成了一个统一的数据集。Planet.osm则是对OpenStreetMap数据的整合，存储于一个单独的文件中。
