Regional ecological continuity (cer_corridor_s_fr32) — Main corridors — SRADDET Hauts-de-France 2020

Representation of wooded, wet, coastal, open and multi-tree corridors, These elements are essential for biodiversity conservation and ecosystem functioning. Without their connectivity, a very large number of species would not have all the habitats necessary for their life cycles. A CER geostandard was established by CNIG in 2018 for harmonisation. http://cnig.gouv.fr/wp-content/uploads/2018/10/181001_Standard_CNIG_CER_v2018.pdf This data is the fixed representation on the date of the vote of the SRADDET (approved by prefectoral decree on 4 August 2020) Consider consulting the recommendations for use in resources https://sig.hautsdefrance.fr/ext/opendata/Sraddet2020/precisions_biodiversite.pdf本数据集涵盖林木覆盖、湿地、滨海、开阔地带及多树廊道的空间表征。上述要素对于生物多样性保护与生态系统功能维持至关重要。若缺乏此类连通性，绝大多数物种将无法获取其生命周期所需的全部栖息环境。 2018年，法国国家地理信息中心（CNIG）制定了CER地理标准（CER geostandard）以实现规范协调。相关标准文档可参考：http://cnig.gouv.fr/wp-content/uploads/2018/10/181001_Standard_CNIG_CER_v2018.pdf 本数据集为SRADDET表决当日的固定空间表征版本，该版本已于2020年8月4日经省长行政令批准。 如需查阅使用相关建议，请参考以下资源：https://sig.hautsdefrance.fr/ext/opendata/Sraddet2020/precisions_biodiversite.pdf
