Overview stability mapping — display service

NOTE! On 1 October 2022, a change of operating environment will be made for this data set, which means that the old display service will stop working. The new link to the display service is available in the distribution tab.

MSB has the Government’s mission to support municipalities and county administrative boards with overviews of soil stability in built-up areas where there are conditions for soil movement. The aim is to identify built-up areas that cannot be categorised as stable. The mapping shall constitute support in the municipality’s risk inventory and risk management and can be used as a basis for the municipality’s master plans. The intention is for the municipality itself to proceed and carry out detailed investigations in designated areas.
Data Reports
• Areas identified as having satisfactory stability.
• Areas which cannot be classified as satisfactorily stable or insufficiently investigated. Due to the lack of buildings, detailed investigation is not recommended.
• Areas which cannot be categorised as satisfactory stable or which are insufficiently investigated and detailed investigation is recommended.
• Areas where detailed investigation is deemed particularly urgent.
• Areas that have previously been classified as satisfactorily stable or which have been reinforced but have not complied with the instructions of the Commission.
• Areas where review of previous investigations and stabilisation measures is considered particularly urgent.
In addition, the data set includes files that appear in the data set that are displayed in the data set, filling, stability measures and stability zones.

Map files in digital form are available for mapping carried out after 2001. The mapping has been carried out in limited areas that are built and where conditions for walking are deemed to exist.
Over time, erosion and human activity can affect conditions.
The overview stability mapping shows the prevailing stability conditions at the time of mapping. The content and reliability of the overview stability maps vary as the methods have been refined over the years. MSB does not make any updates to the material based on changed circumstances or conducted investigations or reinforcements.

注意！本数据集将于2022年10月1日变更运行环境，旧版展示服务将停止运行。新版展示服务链接可在分发选项卡中获取。

瑞典民防与应急管理局（MSB）受政府委托，为各市政当局及郡行政委员会提供建成区土壤稳定性概览数据，以应对存在土壤移动风险的场景。其工作目标为识别无法归类为稳定的建成区域。该测绘成果可辅助市政当局开展风险清单编制与风险管理工作，亦可作为市政总体规划的编制依据。后续将由各市政当局自行推进并在指定区域开展详细勘测工作。

数据报告类别如下：
• 土壤稳定性达标区域
• 无法归类为稳定达标或勘测不充分的区域：因缺乏建构筑物，不建议开展详细勘测
• 无法归类为稳定达标或勘测不充分，且建议开展详细勘测的区域
• 需优先开展详细勘测的区域
• 既往归类为稳定达标，或已采取加固措施但未遵守监管委员会指令的区域
• 需优先复核既往勘测结果与加固措施的区域

此外，本数据集还包含数据集展示所用的相关文件，涵盖填方作业、稳定性加固措施及稳定分区等内容。

2001年之后开展的测绘工作可提供数字格式的地图文件。上述测绘仅覆盖已建成且具备步行通行条件的有限区域。

随着时间推移，侵蚀作用与人类活动可能对土壤稳定性条件造成影响。

本次土壤稳定性概览测绘成果仅反映测绘实施时的实际稳定性状况。由于多年来测绘方法不断迭代优化，本次稳定性概览地图的内容与可靠性存在差异。MSB不会根据环境变化、已开展的勘测或加固工作，对本数据集的材料进行更新。
