Natural threats monitoring

SAR system provides the possibility to monitor vertical ground deformations on a large areas with a millimetre accuracy. Currently available methods of satellite remote sensing provide very accurate information about the surface vertical deformations. SAR radars (Synthetic Aperture Radar) working on orbit gather the radar images of the Earth …

SAR data may be a valuable source of information about the threat of landslides on a large areas. Landslides studies based on SAR data may present different approaches. First of all, SAR images may be used to create Digital Elevation Models (DEM). DEMs are then utilized in the assessment of the risk of landslides occurrence. They may be used in …

The occurrence of sink-hole can be predicted using DInSAR technique. The sink-hole is one of the basic types of vertical land movements. It arises as a result of rocks dissolution caused by surface and ground water. The limestone rocks are most frequently dissolve. The sink-holes appear also in dolomites, marls and gypsums. The sink-hole …

Satellite radars (SAR) provide information about current flood situation regardless of weather conditions. The problem of flood extend monitoring is a very important issue. It can be done based on the remote sensing data acquired using satellite or/and airborne sensors. From all available remote sensing data the SAR images can play the most …
