2018年京津冀OSM路网分布数据

OpenSteetMap是一个自发地理信息系统项目，是一个由公众免费上传、编辑和使用的地理数据集。OSM吸收了一部分商业公司的导航数据, 且有公众自愿上传手持或车载GPS轨迹数据, 因此OSM路网数据具有较高的可靠性。选取OpenSteetMap路网数据中的铁路、高速公路和普通公路，计算京津冀地区每个位置到这三类道路的距离，能够反映出京津冀地区的区域可达性。

OpenStreetMap is a volunteered geographic information (VGI) project, serving as a geographic dataset freely uploaded, edited, and utilized by the general public. OSM incorporates navigation data from some commercial companies, while also receiving voluntary submissions of GPS trajectory data from handheld or in-vehicle devices by the public. Consequently, the road network data from OSM has relatively high reliability. By selecting railway, expressway, and conventional highway data from the OSM road network dataset, and calculating the distance from each location within the Beijing-Tianjin-Hebei region to these three types of roads, the regional accessibility of the Beijing-Tianjin-Hebei region can be effectively reflected.
