Abstract

An assessment of hydro project-related geohazards (AHPRG) has, as its salient features, vast assessed project areas, timeliness, complex objects and contents, lack of large scale geologic maps and poor traffic conditions. Unfavorable factors often hinder engineering geologists arriving at geologic disaster sites successfully and in time. With the development of aerospace science and technology, more and more high-resolution terrain data are being used to assist geohazard assessments To some degree, with this type of assistance, the unfavorable factors inherent in conventional assessment procedures could be mitigated or even overcome. Moreover, some computer operation systems, such as Google Earth, have been developed to build visual terrain models directly on computers and allow users to manipulate the viewing parameters so that they may look at an object from different angles. The RIMS system is just one of these types of systems but, it is unique in that some functions were added to enable users to measure the orientations of engineering geologic features (virtual geologic compass (VGC)) and to directly map what they have observed, etc. After using RIMS and Google Earth in real AHPRG situations, the authors believe that these types of terrain image operation systems would be powerful tools for future AHPRG by combining basic geologic data, geohazard inventories and terrain images from different times. © 2014 American Society of Civil Engineers.
