Qu'est-ce qu'un fichier OSM ?
An OSM file is a street map saved in the OpenStreetMap (OSM) format. It contains XML-formatted data in the form of "nodes" (points), "ways" (connections), and "relations" (street and object properties, such as tags).
Plus d'informations
OpenStreetMap is a global collaborative project that maintains a free, up-to-date planetary map. This map, which is named planet.osm and available for download online, shows streets, geography, landmarks, and other items of interest.
Planet.osm contains a lot of data, so it is an incredibly large file. Users who want to work with smaller sections of planet.osm's data can do so by exporting only that portion of the file from OpenStreetMap.org. For example, a user who wants to export a map of their city can zoom in on their city in OpenStreetMap.org and select . OpenStreetMap.org will then produce a map.osm file that contains the map shown on the user's screen. Users can also download more targeted OSM files from supporting FTP sites, which are linked from OpenStreetMap.org.
Noms de fichiers .OSM courants
