Regional ecological continuity (cer_obstacle_cor_l_fr32) - Barriers to ecological continuity (corridors) - SRADDET Hauts-de-France 2020

Representation of obstacles to the ecological continuity of corridors that play a major role in the degradation of species and natural environments (disruption of movements, migrations, reproductions ...) These obstacles are mainly road or rail networks and areas of pollution of watercourses. A CER geostandard was established by the CNIG in 2018 for harmonisation (cer_obstacle) http://cnig.gouv.fr/wp-content/uploads/2018/10/181001_Standard_CNIG_CER_v2018.pdf This data is the fixed representation on the voting date of the SRADDET (approved by prefectural order on August 4, 2020) Remember to consult the attached recommendations for use in resources https://sig.hautsdefrance.fr/ext/opendata/Sraddet2020/precisions_biodiversite.pdf本数据集旨在表征对生态廊道连续性构成阻碍的各类要素。此类阻碍是造成物种与自然环境退化的核心诱因之一，具体表现为干扰物种的活动、迁徙、繁殖等生命过程。此类阻碍主要包括道路/铁路网络以及河道污染区域。 法国国家地理信息委员会（CNIG）于2018年制定了CER地理标准（cer_obstacle）以实现数据协同统一，相关标准文档可通过以下链接查阅：http://cnig.gouv.fr/wp-content/uploads/2018/10/181001_Standard_CNIG_CER_v2018.pdf 本数据集为SRADDET在投票表决当日的固化表征数据，该数据集已于2020年8月4日经省级行政政令批准生效。 请务必查阅附件中的使用指南文档以规范数据应用：https://sig.hautsdefrance.fr/ext/opendata/Sraddet2020/precisions_biodiversite.pdf
