• Very high spatial resolution sensors can help in<br />
the identification of infrastructure and building<br />
damages [2-3]<br />
• Current and planned sensors pros:<br />
– A variety of spatial and spectral resolutions<br />
– Agility to change acquisition angle to shorten delays<br />
between acquisition dates<br />
– Short revisit time<br />
• Cons:<br />
– Images are HUGE (40 000 x 40 000 pixels for a scene)<br />
– Unwanted details (cars, individual trees and shrubs)<br />
