The 4DSkin solution enables non-contact deformation measurements to be made over large areas of up to several kilometres, at high frequency (typically every 2 minutes) and to a very high level of accuracy (typically 0.2 mm).
4DSkin and its applications
Millimetric monitoring of rock instabilities (excluding vegetation) over large areas, and of large critical structures:
- Landslips
- Hills and Cliffs
- Open-cast mines
- Dams
4DSkin: contactless deformation measurement
4DSkin provides simultaneous remote measurement of thousands of data points over large areas without the need to access the area under observation. Measurement accuracy ranges from 0.1 mm to a few mm for data points up to 3-4 km distant, regardless of weather conditions.
4DSkin generates displacement maps of all pixels in the area, and time-based graphs tracing the evolution each pixel.
4DSkin is based on the use of interferometric synthetic aperture radar technology.
Typical display of results via the Geoscope online platform
- Measurement accuracies range from 0.1 mm to a few mm for data points up to 3-4 km distance
- Sub-millimetric resolution range
- Measurement frequency of the entire zone: 2 minutes
- Maximum measurement distance: 4 km
The 4DSkin solution gives you:
- Remote monitoring of large areas (at high frequency where necessary)
- Reliable, consistent measurements: this system is immune to weather conditions
- Fast installation and configuration: a 100% operational system in a few hours
- Accuracy of between 0.1 mm and a few mm over distances of up to 3-4 km
