Study on the Method of High-precision Geological Hazard Remote Sensing Interpretation of Reservoir in the Mountain and Ravine Region
-
Abstract
The geological disaster investigation on reservoir area is one of the main tasks in engineering geological investigation of reservoir and is of an important basis and primary data of engineering geological evaluation. The traditional method of locating geological disaster needs a lot of manpower and resources, which will normally incur high cost. Also, sometimes it is very difficult or close to impossible to have the research done at the field due to the inconvenient transportation and complex geographic condition. Meanwhile, the restriction of horizon makes it hard for geological engineers to get familiar with geological bodies in a whole. With the advance of RS(remote sensing) application, GIS(Geography Information System) techniques and 3D(three-dimensional) interpretation analysis method, high precision geological hazard investigation can be achieved with fewer field work if the spatial information and 3D visualization technology are used.
