Understanding the effects of glacial isostatic adjustment (GIA) is essential for the assessment of past and future sea-level trends. This study examines the applicability of Small Baseline InSAR to measure GIA-induced vertical land movement in Northern Britain. Different SAR sensors are utilized to cover a time frame of about 20 years. The aim is to establish the spatial distribution of GIA along the coast and uplift centre of Scotland in greater detail compared to results from conventional geodetic techniques, which are interpolated from point measurements. A range of possible error sources within the InSAR processing chain, that lead to orbital and atmospheric artefacts, require to be addressed in order to allow the extraction of any GIA deformation signal. Continuous GPS (CGPS) station coordinates thus need to be integrated with the InSAR data.
