Dataset Direct Download Service (WFS): Mapping of watercourses under GAEC, NTAs and Water Police for 2022

The government instruction of 3 June 2015 requires the State services to carry out a mapping of rivers in each department to facilitate the proper implementation of the water law as well as a guide to the maintenance of rivers.
In the Marne, to avoid multiplying cartographic repositories, the watercourse map reference is unique for:
— the ZNTs
— GAEC
— watercourses water police
The JDD “MAA_June_2021” was built from the hydrographic layer of the Topo BD and based on the field findings made by the DDT de la Marne and the French Office for Biodiversity since 2017.

The ‘TYPE_EC’ field makes it possible to characterise the nature of the flow.

This dataset “MAA_June_2021” corresponds to the flows qualified as rivers under good conditions
agri-environmental (GAEC)

2015年6月3日发布的政府指令要求各省级行政部门开展辖区内河流测绘工作，以保障水法的有效落实，并为河流养护提供指导。
在马恩省，为避免重复建设地图存储库，河流地图索引需统一适用于以下场景：
— ZNTs
— GAEC
— 河道水警
数据集JDD"MAA_June_2021"基于Topo BD的水文图层构建，其数据来源于马恩省DDT（DDT de la Marne）与法国生物多样性办公室（French Office for Biodiversity）自2017年起开展的野外调查成果。
"TYPE_EC"字段可用于表征水流的性质。
本数据集"MAA_June_2021"涵盖了符合优良农业环境条件（GAEC）定义的河流类水流数据。
