This paper presents an integrated approach to landslide research based on remote sensing and sensor networks. This approach is composed of three important parts: (i) landslide susceptibility mapping using remote-sensing techniques for susceptible determination of landslide spots; (ii) scaled-down landslide simulation experiments for validation of sensor(More)
A multi-sensor network for landslide monitoring is under development at Tongji University, Shanghai. The current implementation is setup on a landslide model located in the main university campus. Here the network was tested during some experiments where a landslide runoff was triggered by means of artificial rainfall. The sensor network is based on a(More)
A lot of studies have been done for correcting the systematic biases of high resolution satellite images (HRSI), which is a fundamental work in the geometric orientation and the geopositioning of HRSI. All the existing bias-corrected models eliminate the biases in the images by expressing the biases as a function of some deterministic parameters (i.e.(More)
