Abstract:

The essence of digital landslide technique is to capture basic landside information through remote sensing (RS) and spatial positioning combined with other survey methods; and by using GIS technique to manage and store the digital information; and then based on the landslide-geo-principium to make spatial analysis and establish digital three-dimensional, geo-referenced and multi-elements thematic landslide model serving the landslide survey, monitoring, assessment and disaster prediction and so on. This paper introduces the application for digital landslide technique through 4 examples: ① three dimensional landslide models for Jinlong Mountain；②satellite monitoring Yigong Landslide；③study for landslides in key towns of the Three Gorges；④Qianjiangpin Landslide.

Key words: digital landslide technique, three dimensional landslide model, monitoring of Yigong Landslide, landslides in key towns of the Three Gorges, Qianjiangpin Landslide
