InSAR Svalbard – User requirements, technical considerations, and product development plan

Abstract

The InSAR Svalbard development project (2023–2025) is a partnership between the Geological Survey of Norway (NGU) and NORCE Norwegian Research Centre AS, with funding from the Norwegian Space Agency (Post 74, contract number: 74CO2301). The project aims to start the development of a Ground Motion Service (GMS) in Svalbard, providing spaceborne Synthetic Aperture Radar Interferometry (InSAR) ground displacement maps and time series tailored to Arctic conditions. This report presents the findings from the project's first year, including the outcomes of a user workshop and a user survey conducted in 2023. The study's main goal was to identify the user requirements for an InSAR Svalbard GMS, and to highlight past InSAR research and known for processing limitations. The report also presents a product development plan that considers both user needs and technical considerations.
