Satellite radar interferometry to develop ground deformation maps

Tom Rune Lauknes

Our contribution to the project is related to documenting ongoing landscape changes, mainly due to changes in the permafrost. We will conduct a baseline study prior to the expedition, using historical optical and radar satellite (InSAR) data, to document changes in the ground motion, and to produce segmented vegetation maps. We will also acquire new satellite InSAR data using the Radarsat-2 satellite, allowing to document current-state conditions. During the expedition we will be operating a fixed-wing unmanned aircraft system (UAS), to produce detailed orthomosaics and digital elevation maps. The UAS data will be valuable for documenting landscape changes.
