In the field of road construction, satellite radar interferometry based on high resolution data may be applied to measure the movement of road structures. This study examined first minimum measurement requirements regarding satellite acquisition parameters and road characteristics for the movement monitoring of roads. Fine spatial resolution satellite images, as well as rough textures of road surfaces were shown to be essential for a successful movement monitoring. Then a satellite monitoring test was realized regarding the settlement of a dam with sand over-burden on badly bearing soil using radar reflectors. A parallel terrestrial levelling campaign confirmed the accuracy of 5 mm of the satellite measurements for reflectors not affected by sand removal or too large settlements.
