An Efficient Cutting Algorithm of Remote Sensing Images and Applications in Earthquake Emergency
As is well known,earthquake often inflicts severe casualties and property losses.The occurrence of earthquakes cannot be reliably predicted by current technology,therefore the earthquake emergency and rescue is an important part of protecting against and mitigating earthquake disasters.Remote Sensing (RS) images are important data and information source for Earthquake Emergency Command Systems (EECSs).A large RS image is often extracted into different levels of detail to construct a pyramid structure to acquire more rapid data access.An efficient cutting algorithm of RS images is presented and implemented,with user-friendly interface.The algorithm is verified more efficient and flexible than conventional ones.Using the hierarchical image tiles generated by the algorithm,a simple EECS prototype is implemented and could play an important role in real applications.Test results show that the algorithm is feasible and effective in real applications.
