Simple download service (Atom) of the dataset: Hold of underground cavities in Vienna

Since 2010, the State, in the Department of Vienna, has initiated a series of inventories to assess “cavitated” risk in its territory. In 2010, cavity inventories were carried out by the Bureau de Recherches Géologique et Minières (BRGM). They are based on a national methodology that allows data to be collected from the consultation of available bibliographical references as well as the questioning of all the municipalities of the department.The information concerning all the listed cavities can be found on the site: www.georisques.gouv.fr On the basis of this inventory established in 2010, more detailed inventories were carried out on a selection of municipalities. These studies, conducted by the BRGM, consist of identifying and summarising the cavities present in each communal territory and assessing the issues impacted on the surface. A (non-exhaustive) topographic survey of the cavities was conducted to visualise the ground rights of each underground cavity and thus characterise the surface issues impacted by the presence of these voids. In general, the stakes are people, property, activities... threatened by a hazard (here, the collapse of the soil due to the presence of underground cavities), and who are likely to be affected or damaged by them. The areas impacted by the cavities will need special attention from the local authorities in order to best control urbanisation in under-cavated areas. In addition, in other studies (development of PPRs, geotechnical studies related to development projects) the underground cavity right-of-way was lifted and mapped. This table includes the right-of-way of the underground cavities identified during the various detailed inventories and studies carried out in the department of Vienna.自2010年起，国家已在维也纳省范围内启动一系列清查工作，以评估该辖区内的地下空穴风险。 2010年，法国地质与矿业研究局（Bureau de Recherches Géologique et Minières，简称BRGM）开展了该省的地下空穴清查项目。本次清查遵循国家级统一方法，通过查阅现有文献资料、问询该省所有市镇完成数据采集。所有已登记地下空穴的相关信息均可通过网站www.georisques.gouv.fr查询。 基于2010年完成的本次基础清查，研究团队针对选定的若干市镇开展了更为细致的专项清查。此项由BRGM主导的研究，旨在识别并梳理各市镇辖区内现存的地下空穴，并评估其对地表造成的影响隐患。 研究人员针对部分地下空穴开展了（非全覆盖的）地形测量，以明确各空穴的地表管控范围，进而表征此类地下空洞所引发的地表影响隐患。 总体而言，受该灾害威胁的对象涵盖人群、不动产、生产活动等：它们均面临因地下空穴引发的地表塌陷灾害，并可能因此遭受影响或损失。 受地下空穴影响的区域需得到地方主管部门的重点关注，以便对存在地下空穴区域的城市化进程实施有效管控。 此外，在其他相关研究（如风险预防规划（PPRs）编制、与开发项目相关的岩土工程研究）中，研究人员已明确并测绘了地下空穴的地表管控范围。 本数据集涵盖维也纳省历次详细清查与研究中识别出的地下空穴地表管控范围数据。
