Solution Overview

Being able to analyze damage and changes caused by various natural disasters (i.e., sediment-related disasters, building collapse, and volcanic ash deposits), SAR satellite imagery can assess and measure the degree of damage over a wide-area before and after a disastrous event. One of the major features of SAR satellites is that they can peer through clouds and can penetrate night and bad weather conditions. With SAR image analysis, it is possible to quickly assess the damage situation including in remote areas where it may be difficult to dispatch people on-site. It is also a solution that derives accurate situational understanding and apt initial response with the ability to detect and understand disaster situations over a wide-area and share information quickly with relevant parties.
