| Abstract: | An inventory is presented of researches concerning the use of remote sensing for landslide studies and hazard zonation as mainly carried out in the countries belonging to the European Community. An overview is given of the applicability of remote sensing in the following phases of landslide studies: - 1. (1) Detection and classification of landslides. Special emphasis is given to the types of imagery required at different scales of analysis.
- 2. (2) Monitoring the activity of existing landslides using G.P.S., photogrammetrical techniques and radar interferometry.
- 3. (3) Analysis and prediction in space and time of slope failures. The different factors required in a landslide hazard study are evaluated, and the optimum remote sensing imagery for obtaining each of these factors is indicated.
Examples are given of research work carried out in these three phases from EC countries. Finally an evaluation is given of the aspects of uncertainty associated with the use of remote sensing data, and conclusions are given as to the incorporation of remote sensing techniques within the overall framework of techniques. |
