Big Geospatial Data – Identifying Hazards with GIS Technology

John McCarthy Stage
Stage BAS

Soil movements, e.g. caused by natural or anthropogenic processes, can pose a threat to the population and infrastructure. Therefore, movement processes have been monitored for a long time. Satellite-based methods now make it possible to detect and monitor ground movements with high precision (radar remote sensing). However, these possibilities have so far only been used to a limited extent for everyday applications. With the help of modern GIS tools for handling these BigData data sets (approx. 50 million measuring points for Germany), the BGR (Federal Institute for Geosciences and Natural Resources) is currently developing the German Soil Movement Service (BBD). For this service, Sentinel-1 data from the Copernicus program will be processed and the result presented using WebGIS technologies against the background of a map of Germany. The contribution provides an overview of the challenges and technical solutions for the processing of Big Geospatial Data with GIS technologies and illustrates the added value for safety-relevant tasks using the example of the ground movement service of the BGR.
