We assess the potential in information on rates of vertical land deformation, which is useful for, e.g., climate change adaptation. The optimal results are obtained from observations with a high spatial coverage, such as those from Sentinel-1 Synthetic Aperture Radar Interferometry (InSAR) data. However, challenges exist in creating an awareness of the data and ensuring that end-users at a local level can accurately interpret and efficiently implement them into their respective businesses. We address these challenges via a case study over the low-lying Danish coastal town Thyborøn. This is situated on a sandy coastal barrier on the high-energy North Sea coast by the entrance to the Limfjord. Deformation rates are obtained from time series of precision leveling and GPS measurements as well as ERS-2 and Sentinel-1 InSAR data. The study points to a potential solution for obtaining a public awareness and use of deformation maps
