EO-SCANS - Earth Observation for the Surveillance of Critical Assets for National Security

许多国家资产，如水库堤坝、防洪堤和铁路网，分散在全国各地，需要进行例行监测，因为失败可能会导致严重的人类、环境和经济后果。尽管这些资产的结构很复杂，但小的变形，如路堤的局部滑动、塌陷或差异运动，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，该系统将帮助识别这些变化，并对潜在的严重威胁提供早期预警，使资产管理公司能够更准确地将维护资源集中在风险较大的位置。解决办法是基于一种创新的卫星遥感方法，该方法能够测量所有土地复盖类别上的土地移动的当地趋势，精度达到毫米级。该系统将把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，这将使资产管理人员能够查明潜在的威胁。我们将展示，利用现成的、非侵入性的卫星图像，可以在全国范围内实现具有成本效益的例行资产监测。

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.
