收藏资源简介:
该数据集是法国国家铁路网络(Réseau Ferré National)的形状文件(shapefile),专为地理信息系统(SIG)设计。它包含了与铁路线路几何形状相关的所有信息,由多个文件组成(如SHP、DBF、SHX和PRJ扩展名)。数据集覆盖了全国所有铁路线路,其中线路段被定义为物理上连续的部分,由两个端点节点(起点和终点)界定,并具有一致的参考系统;当存在不连续时,线路被分割为多个段,按递增顺序排列。形状文件的精度为度量级,适用于高比例尺(1/1000至1/5000)使用。线路类型包括:VPL(主线线路)、VPA(其他主线)和VS(服务线路)。数据集最后更新于2024年3月28日。
The dataset is a shapefile of the French National Railway Network (Réseau Ferré National) intended for Geographic Information Systems (GIS). It contains all information related to the geometry of the described objects, consisting of multiple files with extensions such as SHP, DBF, SHX, and PRJ. It covers all railway lines in the national network, where a line section is defined as a physically continuous part of a line, delimited by two endpoint nodes (origin and end), and has a consistent referencing system; when there is discontinuity, the line is divided into multiple sections with increasing ranks. The shapefiles precision is metric, suitable for high scales (1/1000 to 1/5000). The values for the line type column are: VPL = Main Line Tracks, VPA = Other Main Tracks, VS = Service Tracks.
