Line shape file of the National Railway Network

The shapefile format is intended for geographic information systems (GIS). It contains all the information related to the geometry of the objects described. It consists of three files with the same name, with the extensions SHP, DBF (attributes), SHX (geometry index) and PRJ (data projection system). The file contains all the lines of the national rail network. The MNEMO column shows the status of each line: project (PROJECT), operated (EXPLOITE), neutralised (NEUT), neutralised and conserved (NEUT DEF), transferred in service (VS), closed not deposited (FERME ND), closed with lane retention (FERME MV), closed and deposited (FERME D), closed (FERME), closed made available to third parties (FERME DT), entrenched (RETRANCHE), decommissioned not sold (DEC NV), decommissioned sold (DEC V). A section of line is a physically continuous part of a line, bounded by two end nodes (origin and end) of a section of line, and having a coherent tracking system. Where there is a discontinuity, the line is divided into several sections, with an increasing row. The accuracy of the shapefile of the lines is decametric: medium-scale use (1/50.000th). update date 28/03/2024shapefile格式专为地理信息系统（Geographic Information Systems，GIS）设计，用于存储所描述对象的全部几何相关信息。该格式由一套同名配套文件构成，包含扩展名为SHP（几何要素文件）、DBF（属性文件）、SHX（几何索引文件）以及PRJ（数据投影系统文件）的文件。 本数据集涵盖国家铁路网的全部线路数据。 MNEMO字段用于标识每条线路的运营状态，具体包括：规划中（PROJECT）、运营中（EXPLOITE）、停用（NEUT）、停用且保留（NEUT DEF）、移交运营（VS）、未归档关闭（FERME ND）、保留车道关闭（FERME MV）、已归档关闭（FERME D）、已关闭（FERME）、移交第三方使用（FERME DT）、线路加固（RETRANCHE）、未出售报废（DEC NV）、已出售报废（DEC V）。 线路区段指线路上物理连续的一段，以两个线路区段的端点节点（起点与终点）为边界，且具备统一的轨道系统。当线路存在断点时，将被划分为多个区段，并按顺序递增编号。 本线路shapefile的精度为十米级，适用于1:50000比例尺的中尺度应用。 更新日期：2024年3月28日
