Abstract
The usual method for interpretation of collapsed building after any calamity is differential comparison using 3-dimentional data acquired by airborne laser scanner. However, the transmission of the huge amount data to a ground base station in real time has been a big problem. In this research, a realizable compression technique is studied in which the point density required for calamity interpretation is set up and the rate of compression required for the transmission to the ground with the present access speed is defined.
