rapid building damage mapping by optical satellite images

Earthquakes are widely regarded as major disastrous natural events claiming large numbers of lives and economical losses every year in iran or other hazard prone countries. as a repeated experience, in every decade, some major such events have affected seriously urban settings in iran. rapid damage mapping associated to the early phase of post-eventwill help in managing search and rescue operations, resource allocations and preliminary economic loss estimation.earthquake rapid damage mapping in disaster management phases using remote sensing technology is feasible and has been regarded as powerful technique for semi-automatic or automatic building extraction and damage mapping in urbanareas.
