GNSSInSAR
GNSSInSAR is the integrated use of Global Navigation Satellite System (GNSS) measurements and Interferometric Synthetic Aperture Radar (InSAR) data to monitor and analyze ground deformation. The approach combines the strengths of both techniques: GNSS provides precise point measurements of displacement in three dimensions with continuous time series, while InSAR offers dense spatial coverage of line-of-sight deformation over large areas.
InSAR measures surface movement by detecting phase changes between radar images, yielding high-resolution maps of line-of-sight
Common GNSSInSAR approaches include joint inversion or data fusion where InSAR LOS measurements are combined with
Applications span seismology, volcanology, tectonics, landslide monitoring, and infrastructure deformation studies. Advantages include enhanced spatial and
