新的卫星和数据处理技术的出现意味着现在可以在区域和国家范围内对陆地运动进行例行、实用和可靠的调查。在本文中，我们应用一种新的卫星遥感技术，间歇性小基线子集方法，从一个新的卫星使命，哨兵-1的数据，并证明，可以生成一个大面积的地面变形地图，支持一系列能源相关活动的监管。演示区域为苏格兰大陆（约75，000平方公里），陆地运动图需要处理2015年3月至2017年4月期间采集的约627张图像。结果表明，苏格兰各地几乎都遇到了陆地运动，主要是泥炭地地区的沉降。然而，也遇到许多其他现象，包括与采矿和土木工程活动有关的滑坡和变形。特别考虑到英国第14轮陆上许可证发放下提供的石油勘探和开发许可证区域，显示了陆地运动类型的示例，包括与风电场土壤恢复相关的示例。它表明，至少在苏格兰，几乎所有的许可证领域包含一种或另一种形式的变形，而且，这种沉降的原因是动态的，可能会改变从一年到一年。因此，这样的地图很可能在监管框架中发挥巨大作用，以查明许可证领域预先存在的问题，并确保一旦活动开始就建立正确的监测框架。它们还可以提供良好做法的证据，并保证不会受到第三方的诉讼。
The advent of new satellite and data processing techniques have meant that routine, operational and reliable surveys of land motion on a regional and national scale are now possible. In this paper, we apply a novel satellite remote sensing technique, the Intermittent Small Baseline Subset method, to data from a new satellite mission, Sentinel-1, and demonstrate that a wide area map of ground deformation can be generated that supports the regulation of a range of energy-related activities. The area for the demonstration is mainland Scotland (∼75,000 km2) and the land motion map required the processing of some 627 images acquired from March 2015 to April 2017. The results show that land motion is encountered almost everywhere across Scotland, dominated by subsidence over peatland areas. However, many other phenomena are also encountered including landslides and deformation associated with mining and civil engineering activities. Considering specifically Petroleum Exploration and Development Licence areas offered under the 14th Onshore Licensing Round in the UK, examples of the types of land motion are shown, including an example related to soil restoration by a wind farm. It is demonstrated that, in Scotland at least, almost all licence areas contain deformation of one form or another and, furthermore, the causes of that subsidence are dynamic and likely to be changing from year-to-year. Therefore, maps like this are likely to be of enormous use in a regulatory framework to scope out pre-existing problems in a licence area and to ensure that the correct monitoring framework is put in place once activities begin. They can also provide evidence of good practice and give assurance against litigation by third parties.
