Sites listed in Cartofriches - Hauts-de-France

Background: the Cartofriches System The main need that Cartofriches wishes to address is the help in the census of brownfield sites to qualify them and facilitate their reuse. Despite the existence of national bases such as BASIAS and BASOL and high-quality local observatories, knowledge of brownfield sites at national level has so far remained partial and diffuse because of the diversity of cases and the rapid evolution of sites. The objective of Cartofriches, in the long term, is thus to support developers and developers of rehabilitation projects by setting up a national inventory of available brownfield sites. The data table produced as part of this project, which brings together national and local data, is available in opendata. Access the Cartofriches data visualisation application: https://cartofriches.cerema.fr/ Description of the Cartofriches data table The data table available in opendata makes it possible to reference potentially fallow sites. The term ‘fallow land’ is taken here in the sense of artificialised and unoccupied spaces. The data table contains information on the location of these sites (geographic coordinates, parcel identifiers, geolocated polygons, etc.), but also context information (type of owner, pollution status, urban planning law, etc.). The sources that made this table possible In order to build up a national brownfield inventory database, Cerema relied on several data sources. National data sources identified almost 3000 sites across the country. Cerema is continuing this national census work, which for the time being makes it possible to have only a sample of all existing brownfield sites. The national data used and information on treatments are available here: https://artificialisation.biodiversitetousvivants.fr/cartofriches/donnees-used The gathering of local data, as close as possible to the field, makes it possible to complete Cerema's work at the national level, and will ultimately constitute a strong added value of the system. These local data are transmitted by local actors, who have an observatory or carry out studies. Local contributors to Cartofriches are listed here: https://artificialisation.biodiversitetousvivants.fr/cartofriches/local observatories Quality and limitations of data use At this stage, the data table is not homogeneous throughout the national territory. Indeed, the territories for which local data exists in Cartofriches actually have more sites. The purpose of the data table is to provide a list of potentially brownfield sites: it is not intended to be exhaustive. On the other hand, the fields in the data table have been harmonised to bring together information from multiple sources. This made it possible to form a single table, but it also implies that not all fields are necessarily filled in.背景：Cartofriches系统 Cartofriches旨在解决的核心需求，是助力棕地（brownfield sites）的普查工作，以完成其资质认定并推动再利用。 尽管已存在BASIAS、BASOL等国家级数据库，以及一批高质量的地方观测机构，但由于棕地案例类型多样、场地快速演变，目前国家级层面的棕地相关认知仍零散且不全面。 因此，Cartofriches的长期目标，是通过构建国家级可复用棕地清单，为改造项目开发者提供支持。 本项目产出的数据集表格整合了国家级与地方级数据，已以开放数据（Open Data）形式对外发布。 可访问Cartofriches数据可视化应用：https://cartofriches.cerema.fr/ Cartofriches数据集表格说明 本开放数据平台提供的数据集表格，可用于标记潜在闲置场地。此处所指的"闲置用地"，定义为已人工改造且未被占用的空间。 该数据集表格不仅包含此类场地的位置信息（地理坐标、地块标识符、地理定位多边形等），还涵盖相关背景信息（业主类型、污染状况、城市规划法规等）。 数据集表格的构建来源 为搭建国家级棕地普查数据库，Cerema依托了多类数据源。 国家级数据源已在全国范围内识别出近3000处场地。Cerema目前仍在推进全国普查工作，截至当前，仅能获取现有棕地的样本数据。 本次使用的国家级数据及相关处理说明可访问：https://artificialisation.biodiversitetousvivants.fr/cartofriches/donnees-used 收集贴近实地调研的地方级数据，可补充Cerema的国家级普查工作，最终将成为本系统的核心增值亮点。 此类地方数据由地方相关机构提交，这些机构要么设有观测站点，要么开展相关研究。Cartofriches的地方贡献者名单可访问：https://artificialisation.biodiversitetousvivants.fr/cartofriches/local observatories 数据使用的质量与局限性 现阶段，该数据集表格在全国范围内的覆盖度并不均匀：事实上，已接入地方数据的区域，其收录的场地数量更多。 本数据集表格的定位为提供潜在棕地清单，并非旨在实现完全穷尽式收录。 另一方面，数据集表格的字段已完成统一协调，以整合多源数据。此举虽促成了单一张量表格的形成，但也意味着并非所有字段均会被完整填写。
