An effective tool for ground deformation monitoring
For years, scientists dreamed of a “geodetic camera” which would be able to snap a detailed picture of how much the ground is moving. The dream has become reality: colorful images of surface deformation are being produced from data acquired by spacecrafts.
Or structures not monitored at all! Bridges, dams, urban areas and historical buildings are not under vital surveillance
Under potential risk
Structures are built in close vicinity to hazardous slopes or are threatened by landslides, earthquakes or human-induced changes
Expensive in-situ monitoring
Terrestrial health checks are costly in terms of time, equipment and labour. Spatially extensive areas (hundreds of kilometres) are hardly observable
