    Abstract

    The objective of this research was to map centimeter-scale soil movements on slopes that are prone to landslides. These small movements can be used as possible signs of an approaching larger landslide or rock fall. Two methods were used: an interferometric technique using TerraSAR-X data and a ground based technique with a theodolite and prisms. The study area - in a mountainous area - is characterized by high annual rain fall. TerraSAR-X is space-borne synthetic aperture radar operating in 3-cm wavelength. The TerraSAR-X dataset consisted of a sequence of 5 scenes. A soil movement of 1.55 cm was mapped with the interferometric technique in a broken nail-stabilized slope area. The corresponding movement (between 12 and 23 January 2009) by theodolite measurement was 2.65 cm. The interferometric technique measured the movement of a larger area while the theodolite measurement was a point measurement, which may explain part of the differences. More reliable theodolite measurements are preferred in areas with easy access while interferometric techniques can also be used in inaccessible areas.
