Application of remote sensing image to large scale landslide research
871115 Identifying hydro resources with enhanced satellite imagery Cambndge. M; Moore, M M; Canas, A A Int Water Power Dam Constr 1’38, NIO, Ocr 1986. P13-17 Landsat multi-spectral scanner imagery, together with available topographical and geological maps, was used during preliminary studies of potential dam sites in peninsular Malaysia. The Imperial College prototype analogue image processing system was used to provide colour composites and edge enhanced images for drainage, fold, fault and joint mapping. and to provide information on rock type distribution. Remote sensing is seen to be an effective and economic preliminary surveying tool. 871116 Aerial prospecting Hood, P Min Mag Aug 1986, P91-113 A state-of-the-art description of aerial prospecting is presented. Firstly, the economics of aerial prospecting are considered. Aeromagnetic survey techniques using fluxgate proton magnetometers are precession and optical absorption described, then airborne electromagnetic, gravity and radiometric techniques and remote sensing techniques, satellite imagery, airborne radar and infrared mapping. Finally integrated geophysical systems, airborne positioning systems and data acquisition and processing systems are described. 871117 On the hazard map of landslide using photo interpretation Nakasuji, A; Imamura, R; Manzen, H Proc 4th Znternutionai Conference and Field Workshop on Landslides, Japan,23-31 Aug 1985 PSS-62. PubI Tokyo: Japan Landslide Society. I985
Description of how to estimate the ratio of landslides hazard in wide areas, by using the aerial-photointerpretation method, and results of its application in the upper reaches of the Tenryu River, Japan, are summarized. 871118 Application of remote sensing image to large scale landslide research Wang, Z H Proc 4th International Conference and Field Workshop on Landslides, Japan,23-31 Aag 1985 PI85IN. Pub1 Tokyo. Japan Landslide Society, 1985
A remote sensing test was carried out in the western part of China in 1981. During the test, the landslides distributed along the bank of the Ya Long Jiang river were studied. By combining image interpretation with field investigation, some aspects of landslides such as microfeatures, movement types, volume estimation, geotogical formations, dynamic characteristics and prediction were examined. Case studies of three massive landslides are presented.

Historical records of 1663 describe high levels of silting m streams for up to several months.

The design, processing and presentation of the database are described. The use of surface analysis computer packages allows quantifiable reproduction of the database in any chosen plane. The database is continually updated, increasing accuracy, as new information becomes available. It allows rapid site analysis, but does not supersede the need for thorough ground investigation. 871122 Assessment of slope stability in the Riepalese hiiddie Mountains Kienholz, H Froc 4th international Conference and Field Workshop on Landslides, Japan,23-31 Aug 1985 PS-IO. Publ Tnkyo:~Japan Land&de Society, 1985
The major original purpose of the Mountain Hazards Mapping Project in Nepal was to develop methods for assessing slope stability in the densely populated hill area. In a testarea near Kathmandu, significant basic data (actual damage, ground parameters, actual land use, existing preventive measures and other human influences) were gathered, and- a IMap of Mountain Hazards and Slope Stability was made. A major attempt is being made to deveiop a simple method- which allows rapid assessment erosion and landstide hazard while assuring sufficient accuracy and objectivity. A set of logical trees are proposed for use in the procedure. The procedure and the first results are discussed.

Landslide hazard and risk maps should provide information needed to judge the impact that the hazard would have on people and structures at risk. Several examples are provided of innovative maps from Italy, France, Switzerland, New Zealand, Japan and the United States, that provide some or most of the information needed. Auth. 61 refs.
