Natural risks are unpredictable, dangerous and may be widespread. It is often not
straightforward, cost-effective, or accurate to use metrological sensors in the
ground, for example, to study and track their global evolution. The use of image
data is a powerful way to do this: this: imaging technology enables the phenomena
to be observed continuously, safely, and economically without the use of expensive equipment for a single purpose. High-resolution, multispectral, and
remote/proximal sensing can be achieved with standard imaging technologies.
Once the image/video data is acquired, research into image/video processing is
subsequently necessary to obtain useful and timely information about the nature of the risk arising from the natural phenomena drawing on a range of techniques in a well-established and productive field of research.
The use of satellite, multispectral radar, and stereo images combined with
image/video processing for the study of natural risks which may include:
