Ground Motion Service Germany (BBD) 2015-2021 L3 Vertical
Description
The diverse geology of Germany and the resulting use are the causes of a wide variety of ground motions, such as soil compaction, landslides, groundwater extraction, natural gas extraction, (abandoned) mining and cavern storage operations. The products of the Ground Motion Service Germany (BBD) are based on SAR data from the Copernicus Sentinel-1 mission and Persistent Scatterer Interferometry (PSI) processing. The BBD portal contains PSI data from the entire Federal Republic of Germany (approx. 360,000 km²). PSI technology enables precise measurements of ground motions in the mm range. The decomposed virtual PS are visualized according to the mean velocity along vertical direction according to the following convention in the BBD portal: - the green color corresponds to the virtual PS, whose average speed is very low, between -2.0 and +2.0 mm/year, i.e. in the sensitivity range of the PSI technology; - those virtual PS with a negative movement rate are visualized in the colors from yellow to red, i.e. downward movement; - the colors from turquoise to blue visualize those virtual PS with a positive movement rate, i.e. upward movement. The precision of the PSI data presented is on the order of typically +- 2 mm/year for the average velocity.
