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 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)
The purpose of this article is to extract geometric features and other information for polyhedron, then using these features and information to build the model of object. In this essay, polyhedron refers to objects such as buildings. Unlike modelling objects in other fields, like reverse engineering, buildings' surface usually consists of large amount of(More)
