The use of remote sensing and spatial information is becoming increasingly prevalent for many different environmental applications. In particular the potential of remote sensing for providing information relating to geological hazard assessment is gaining momentum as data becomes more readily available, and awareness of the technology is enhanced in the community. Remote sensing remains the only way of providing broad scale assessments of environmental features and processes, such as information relating to vulnerability to geological hazards and/or damage assessment post event.
The report by Joyce et al., 2011 documents the remote sensing data and image processing techniques that are commonly used for mapping and monitoring several geohazards known to be of significance in South Africa. It discusses the relevant geological hazards to South Africa including landslides, seismic hazards, deformation due to mining, sinkholes, tsunamis, erosion and problem soils. The remote sensing data and the image processing techniques for each hazard are provided. The focus is on the use of optical imagery, LiDAR (light detection and ranging), and synthetic aperture RADAR.
