“…In rare occasions, an exception of this general rule might be high-frequency imaging (e.g. monitoring of meteorological events, Kniveton et al, 2000;Buchroithner, 2002). However, the early warning from impending disasters is an ultimate, long-term goal of earth observation from space and air, and of the related technological development.…”

Abstract. Process interactions and chain reactions, the present shift of cryospheric hazard zones due to atmospheric warming, and the potential far reach of glacier disasters make it necessary to apply modern remote sensing techniques for the assessment of glacier and permafrost hazards in highmountains. Typically, related hazard source areas are situated in remote regions, often difficult to access for physical and/or political reasons. In this contribution we provide an overview of air-and spaceborne remote sensing methods suitable for glacier and permafrost hazard assessment and disaster management. A number of image classification and change detection techniques support high-mountain hazard studies. Digital terrain models (DTMs), derived from optical stereo data, synthetic aperture radar or laserscanning, represent one of the most important data sets for investigating high-mountain processes. Fusion of satellite stereo-derived DTMs with the DTM from the Shuttle Radar Topography Mission (SRTM) is a promising way to combine the advantages of both technologies. Large changes in terrain volume such as from avalanche deposits can indeed be measured even by repeat satellite DTMs. Multitemporal data can be used to derive surface displacements on glaciers, permafrost and landslides. Combining DTMs, results from spectral image classification, and multitemporal data from change detection and displacement measurements significantly improves the detection of hazard potentials. Modelling of hazardous processes based on geographic information systems (GIS) complements the remote sensing analyses towards an integrated assessment of glacier and permafrost hazards in mountains. Major present limitations in the application of remote sensing to glacier and permafrost hazards in mountains are, on the one hand, of technical nature (e.g. combination and fusion of different methods and data; improved unCorrespondence to: A.

On the other hand, better dissemination of remote sensing expertise towards institutions involved in high-mountain hazard assessment and management is needed in order to exploit the large potential of remote sensing in this field.

“…Consequently, it requires knowledge of the factors determining the probability of landslide for a particular slope or area, which according to Dai et al (2002) can be grouped into two categories: (1) preparatory variables which make the slope susceptible to failure without triggering it, such as geology, slope gradient and aspect, elevation, soil geotechnical properties, vegetation cover and long term drainage patterns and weathering; and (2) the triggering variables such as heavy rainfall, glacier outburst. As shown in Table 1, remote sensing has been used in the detection and identification of diagnostic features mostly related to the first category, and to a lesser extent, to the detection of potentially triggering factors as shown by studies of Kniveton et al (2000), Buchroithner (2002), Huggel et al (2002), Kääb et al (2003).…”

“…Particularly, the "5.12 large earthquake" had occurred in Yingxiu fracture, as shown in figure 1. Due to the influence of the earthquake, surface rock mass of mountains was broke in the study area, so geological hazards, such as collapse, landslide, debris flow, etc., may seriously affect the highway construction [3]. Meanwhile, it is difficult to explore the study area manually because of the dense vegetation and complicated conditions.…”

Abstract-In order to realize the efficient organization of the engineering geological information, the GIS management platform was proposed, which can realize the comprehensive management of RS interpretation results and GPS positioning. Based on a highway, the management pattern of multi-source, multi-date and multi-resolution image data was adopt. Moreover, the fast display and overlapping display of vector data and image data as well as the integrated management of image data were employed. Meanwhile, comprehensive analysis and dynamic management of engineering geological conditions of the corridor zone along the highway were implemented.
