Highways in OpenStreetMap

Daily extract of the **autoroutes (infrastructure)** in metropolitan France present in the OpenStreetMap (OSM) open and collaborative database [1].

The layer is available in [MAGOSM](https://magosm.magellium.com/)
— accessible via public WMS and WFS services
— viewable, searchable and downloadable via the portal
— analysable over the last 30 days via the Change Tracking Portal

**Data model**
The OSM attributes used to filter the data are:

* highway = motorway
* highway = motorway_link
* highway = motorway_junction

Additional OSM attributes have been selected to enrich the main tags.
All attributes prefixed by “osm” (e.g. osm_user, osm_id...) are common properties similar to meta-data on the OSM object.

More information about:

* the **motorway-specific data model** on the OSM Wiki page — WikiProject_France/Autoroutes [2].
* the **general OSM data model** is documented on the OSM Wiki page — Map Elements [3].
* the **modes and frequencies of use and combination of different attributes** within the OSM community on the TagInfo France service [4]

本数据集为每日提取自开放协作型数据库**开放街道地图（OpenStreetMap，简称OSM）**[1]中的法国本土高速公路（autoroutes，基础设施类别）数据。

该数据集图层可通过[MAGOSM](https://magosm.magellium.com/)获取，具体支持以下功能：
- 可通过公开的Web地图服务（WMS）与Web要素服务（WFS）访问；
- 可通过门户平台进行浏览、检索与下载；
- 可通过变更追踪门户对近30天内的数据开展分析。

**数据模型**
用于筛选数据集的OSM属性包括：
* `highway = motorway`（高速公路）
* `highway = motorway_link`（高速公路连接道）
* `highway = motorway_junction`（高速公路枢纽）

为丰富核心标签集，还选取了额外的OSM属性。所有以“osm”为前缀的属性（如`osm_user`、`osm_id`等）均为通用属性，类同于OSM对象的元数据。

更多相关信息可查阅以下资源：
* OSM维基页面`WikiProject_France/Autoroutes`[2]中记载了**高速公路专属数据模型**的详细内容；
* OSM维基页面`Map Elements`[3]中记录了**通用OSM数据模型**的官方文档；
* TagInfo France服务[4]提供了OSM社区内各类属性的使用模式、频次与组合方式的相关信息。
