This paper assesses the value of high temporal frequency satellite data with various spatial sampling resolutions for multi-scalar historic environment survey and management use cases in Scotland, specifically for broad-brush landscape characterisation, for monitoring the condition of monuments and for the discovery of otherwise unknown sites. Dealing with a part of the world where applications of satellite imagery are almost entirely unexplored, this study takes a real-world approach, which foregrounds the purpose at hand rather than presenting a case study from an optimal setting. The study highlights the importance of detailed imagery to support interpretation in some instances, and the challenges of obtaining time-critical optical imagery in a part of the world that experiences significant periods of cloud cover. The real-world availability of data in such settings is assessed, highlighting that even with daily revisits, useable imagery cannot be guaranteed. The implications of current and past tasking patterns for availability of high-resolution data now and in the future are discussed. The study identifies the complementary roles that satellite imagery can fulfil, while identifying the limitations that remain to fuller applications of such data, in a study that will be relevant to many parts of Europe and beyond.

对历史环境应用的高时间频率卫星数据的评估。苏格兰的案例研究

本文评估了具有各种空间采样分辨率的高时间频率卫星数据对于苏格兰多标量历史环境调查和管理用例的价值，特别是对于粗略的景观特征描述、监测纪念碑的状况以及发现其他方面未知站点。这项研究针对的是世界上卫星图像应用几乎完全未被探索的地区，采用了现实世界的方法，它突出了当前的目的，而不是从最佳环境中提出案例研究。该研究强调了在某些情况下详细图像支持解释的重要性，以及在世界上经历大量云层覆盖的地区获取时间关键的光学图像的挑战。对此类环境中数据的现实可用性进行了评估，强调即使每天重新访问，也无法保证可用的图像。讨论了当前和过去的任务分配模式对现在和未来高分辨率数据可用性的影响。该研究确定了卫星图像可以发挥的补充作用，同时确定了这些数据在更全面应用方面仍然存在的局限性，这项研究将与欧洲及其他地区的许多地区相关。
