Geomatics Technologies for Hazards Mitigation

Abstract eng:
Three modern geomatics technologies (Global Navigation Satellite Systems GNSS, Geospatial Information System/Science GIS, and Remote Sensing RS) can have significant contributions to hazards mitigation. GNSS is used to precisely monitor the deformations at scale from global, regional to engineering structures in real time mode or in post-processing mode; GIS offers powerful tool to manage high volume of spatial data in both vector and raster forms, a number of spatial analysis functionalities, and ability to display and visualization of the data in various ways; RS with its capability of acquiring both geometric and physical information of objects under study is an outstanding tool for many kinds of studies in a larger area. Although GPS and RS are mainly used for data acquisition and GIS for data management and analysis, they are integrated in many applications. This paper presents the recent developments in these technologies with a focus on hazard mitigation. A particular emphasis will be in the area of earthquake engineering.
