OpenStreetMap (OSM) is a collaborative, open geographic database project that creates and maintains freely reusable spatial data about features and places around the world [1][2]. Its data are contributed and updated by a distributed community of volunteers and other participants, who use sources such as local knowledge, GPS observations, and aerial imagery to map geographic features [1]. The database represents real-world entities—including roads, paths, buildings, land use, and points of interest—as structured geographic objects with associated attributes [1][3]. OpenStreetMap is a prominent example of volunteered geographic information (VGI), in which geographic data are collected and maintained through distributed contributions rather than exclusively by a single authoritative mapping agency [3]. Its data can be downloaded, analysed, edited, and incorporated into mapping applications, navigation systems, and GIS workflows [1][2].
