Many national assets, such as reservoir embankments, flood defences and the rail network, are dispersed around the nation and require routine monitoring as failure can result in severe human, environmental and economic consequences. Although the structure of these assets are complex, small deformations such as a localised slip, slump or differential motion in an embankment, can provide clues that there are issues requiring immediate investigation. In this project, we propose a monitoring system that will help identify these changes and provide an early warning of potentially serious threats, enabling asset managers to more precisely focus maintenance resources on those locations at greater risk. The solution is based upon an innovative satellite remote sensing method capable of measuring local trends in land movement over all land cover classes to millimetric accuracy. The system will combine Earth Observation data with a novel data processing technique and will provide regional measurements of ground stability at regular temporal intervals which will enable asset managers to identify potential threats. We will show that cost-effective routine asset monitoring can be achieved at a national scale using readily available, non-invasive, satellite imagery.

许多国家资产，如水库蓄水、防洪和铁路网络，分散在全国各地，需要进行例行监测，因为故障可能导致严重的人类、环境和经济后果。虽然这些资产的结构很复杂，但路堤中的局部滑动、坍塌或差异运动等小变形可以提供线索，表明存在需要立即调查的问题。在这个项目中，我们提出了一个监测系统，将有助于识别这些变化，并提供潜在的严重威胁的早期预警，使资产管理人员能够更准确地集中在这些地点的维护资源风险更大。这一解决办法是以一种创新的卫星遥感方法为基础的，这种方法能够测量所有土地覆被类别的土地移动的局部趋势，精确到毫米级。该系统将把联合收割机地球观测数据与一种新的数据处理技术结合起来，并将定期提供地面稳定性的区域测量数据，使资产管理者能够查明潜在的威胁。我们将表明，具有成本效益的例行资产监测可以在全国范围内实现使用现成的，非侵入性的，卫星图像。
