Shifting land won't stop your journey
23 June 2014
Subsidence, rockfalls and landslides threaten potentially devastating human and economic consequences across Europe - but satellites can help.
Traditional monitoring such as photographic mapping to measure changes in the landscape works well for specific locations but is labour intensive and costly. Now, ESA has looked at using satellites to watch for hazards across broad areas that could affect road and rail networks.
The outcome is so promising that the resulting monitoring services continue to be developed by the companies involved in the two projects.
The services rely on a triple space alliance of satellite radar images, combined with satnav using satcoms to relay in-situ observations to a central system for analysing ground motion around road and rail networks.
