than ground surveys or GPS monitoring, at +-10mm and +-20mm respectively. 11 InSAR has also become the most accurate land deformation monitoring technique according to Farmonaut’s data, as the only method above 90% accuracy in results. 12 Therefore, as market size and technology advancements continue to improve, there is no doubt that the sector will continue to grow. This means that urban usage of InSAR is independently far more plausible in the next decade regardless of action taken today. Conclusion Consequently, the expansion in accessibility of InSAR technology will undoubtedly improve the disaster resilience of ground deformation events in the UK. Practical drawbacks – such as the varied scattering environments – are temporary in impact as technology continues to advance in the sector, and only reduces the cost-benefit analysis for urban use. Furthermore, the resulting information from the mapping of nationwide urban application of InSAR can certainly become imperative for other sectors, such as urban planning and sustainability. Thus, despite potentially high investment costs, a national-scale access to InSAR data is a long-term benefit for land deformation resilience in the United Kingdom.
