The ground surface in the UK is far from stable. For example, there are more that 15,000 recorded landslides in the UK, and the average annual cost of ground movement to the insurance industry is £250M. Landslides affecting critical infrastructure, such as mainline railways or dams, can be associated with multi-million pound remediation costs even for a single slope failure event. Furthermore, there are tens of thousands of kilometres of engineered slopes in our transportation, utilities and flood defence infrastructure networks - many of which were built in Victorian times and are in poor condition. Satellite technology, specifically ESA's Sentinel-1 constellation, has the potential to produce a dynamic, high resolution map of ground motion which can be used for monitoring and planning. The proposed feasibility study will explore whether UK expertise can be used to integrate Sentinel-1 data with sensors on the ground and embedded in the built environment to contribute to the Digital Environment. The study will leverage existing RCUK investments, map the requirements of potential stakeholders and explore cutting edge approaches to data handling, analysis, fusion and decision making. In addition to the core of InSAR experts, our team comprises a) specialists in image processing and machine learning, b) specialists in landslides, subsidence and onshore energy production and c) two knowledge exchange fellows. A wide-ranging network of potential stakeholders has already been identified, and our selected project partners (Environment Agency, Network Rail, TerraDat, Bridgeway Consulting) represent the needs of key governmental and commercial beneficiaries. The output of the feasibility study will be a peer-reviewed white paper detailing the requirements for a Sentinel-1 based UK ground motion map to be incorporated into a Digital Environment.

英国的地面很不稳定。例如，英国有超过15,000起有记录的山体滑坡，保险业平均每年的地面移动成本为2.5亿GB。影响关键基础设施的山体滑坡，如主线铁路或水坝，可能会与数百万英镑的补救费用相关，即使是一个单一的斜坡坍塌事件。此外，我们的交通、公用事业和防洪基础设施网络中有数万公里的工程斜坡-其中许多建于维多利亚时代，状况很差。卫星技术，特别是欧空局的哨兵一号星座，有可能制作出动态、高分辨率的地面运动地图，用于监测和规划。拟议的可行性研究将探索是否可以利用英国的专业知识将哨兵1号数据与地面传感器整合起来，并嵌入到建成的环境中，为数字环境做出贡献。这项研究将利用RCUK现有的投资，绘制潜在利益相关者的需求图，并探索数据处理、分析、融合和决策的尖端方法。除了InSAR专家的核心，我们的团队还包括a)图像处理和机器学习专家，b)滑坡、下沉和陆上能源生产专家，以及c)两名知识交流研究员。已经确定了一个广泛的潜在利益攸关方网络，我们选定的项目合作伙伴(环境署、Network Rail、TerraDat、Bridgeway Consulting)代表了主要政府和商业受益者的需求。可行性研究的结果将是一份同行评议的白皮书，详细说明将基于哨兵1号的英国地面运动地图纳入数字环境的要求。
