The challenges of research and surveys for ground motion patterns are of high importance from both a scientific and engineering perspective. These can be related to natural phenomena, such as tectonic or geomorphological processes; or to anthropogenic activities, such as the study of surface deformation patterns associated with mining activities, groundwater and fluid extraction. The knowledge of the movement study characteristics of our immediate built environment is also a high priority, important for all of us. For all these challenges, Synthetic Aperture Radar Interferometry (InSAR) provides a spatially high-resolution and large-scale observation and monitoring capability, capable of mapping and monitoring the above deformation patterns with millimetre-scale accuracy.

(LTK-SGO) presents “InSAR.Hungary: Hungarian INSAR-based ground motion monitoring system“, a unified ground motion database for the whole territory of Hungary. It provides a multi-level result product representation of the surface deformation history of Hungary between 2015 and 2023, derived from Sentinel-1 L1 SLC data using the method of Persistent Scatterer Interferometry (PS-InSAR). In doing so, the synergy between InSAR and GNSS technologies are also exploited in an integrated way; namely, PS-InSAR technology provides the local, i.e. spatially short wavelength and high resolution deformation pattern components, while the GNSS technology-based EPND velocity model provides the spatially long wavelength deformation components.
Using 'Application' gives free browsing insight into the deformation rate fields of the L3A and L3B outcome products. This products provide results for the vertical and East-West horizontal components modelled on a regular grid, which are derived from linear deformation rates (mm/year) associated with deformation patterns determined over the study period. While the purely PS-InSAR based L3A outcome product is representative of the local deformation patterns; the L3B outcome product provides a complex solution based on PS-InSAR and GNSS ground motion analysis results by using the EPND velocity model as a reference.
As LTK-SGO strives for innovation, we are dedicated in further development and upgrade of InSAR.Hungary, including updating the outcome results, expanding both the spatial and temporal coverage, as well as broaden the set of freely available product levels and user-site features of the application.
