20 km wide corridor on both sides of the gas transmission system

20 km wide corridor on both sides of the gas transmission system. This corridor was calculated on the basis of the data “simplified trace of the precise GRTgaz network to approximately 250 m](https://odre.opendatasoft.com/explore/dataset/trace-du-reseau-grt-250/information/)” and “[simplified trace of the precise TEREGA network to approximately 250 m](−) present on the [ODRÉ] platform. This dataset reflects the presence of a gas transmission network within a 20 km radius at any point within the corridor. Be careful! This information does not accurately identify the presence or absence of networks or pipelines in a given geographical area. Under no circumstances can you use them for works on roads. In this context, only information obtained via the teleservice (one-stop shop) http://www.reseaux-et-canalisations.ineris.fr shall be authentic以输气系统两侧为基准的20千米宽廊道。 该廊道基于发布于[ODRÉ]平台的两份数据计算得到：分别为「精确GRTgaz管网简化至约250米的迹线」（https://odre.opendatasoft.com/explore/dataset/trace-du-reseau-grt-250/information/）与「精确TEREGA管网简化至约250米的迹线」（−）。 本数据集用于表征该廊道内任意点位周边20千米半径范围内存在输气管网的情况。 请注意！本信息无法精准识别特定地理区域内管网或管道的实际存在与否。严禁将其用于道路工程相关工作。在此情形下，仅通过一站式远程服务平台http://www.reseaux-et-canalisations.ineris.fr获取的信息方为有效。
