Dataset Direct Download Service (WFS): Artificialisation of agricultural and forestry natural areas (approach by Sitadel)

Artificialisation can be defined as “the transformation of natural soil, agricultural or forestry, through management operations which may lead to partial or total waterproofing” (CEEREMA definition). This is a major challenge in Île-de-France where land pressure is high, including a significant need for housing construction and development of transport and rare natural, agricultural and forestry areas to be protected. The Sitadel database is managed by the Department of Data and Statistical Studies of the MTES. Information is provided by the Building Permit Instructors Centres. Indeed, any petitioner planning a new construction or the conversion of a construction requiring the deposit of a building permit, must complete a form relating to his project and send it to the town hall of the municipality where the works are located or the service of the competent State. The movements relating to the life of the permit (deposit, authorisations, cancellations, modifications, start-ups, completions of works) are detailed. Sitadel does not contain any raw data concerning the artificialisation but tells us the square meters put into construction declared each year and therefore what should be built in the coming years. This is another way to monitor the evolution of soil artificialisation.土壤人工硬化（Artificialisation）可被定义为"通过各类管理作业对自然土壤、农用地或林地进行改造，使其具备部分或完全不透水特性"（CEEREMA定义）。在法兰西岛大区（Île-de-France），该问题已成为重大挑战：区域土地压力居高不下，既要满足住房建设与交通设施开发的旺盛需求，又需对稀缺的自然、农业及林地资源加以保护。 西塔德尔（Sitadel）数据库由MTES的数据与统计研究部门负责管理，数据来源于建筑许可指导中心。 事实上，所有计划开展新建工程或改造工程且需提交建筑许可申请的申请人，均需填写对应项目的申报表格，并提交至工程所在地的市政厅或主管国家职能部门。建筑许可全生命周期内的各项流程——包括许可提交、审批、撤销、变更、开工及竣工——均有详细记录。 西塔德尔数据库并未直接收录土壤人工硬化的原始数据，但其统计了每年申报的在建施工面积，由此可推知未来数年的建设规模，这亦是监测土壤人工硬化演变趋势的有效补充路径。
