Abstract :
The emergency decision-making by government for rescue and rebuilding after a catastrophic earthquake depends on fast, accuracy and quantitative disaster information. The development of GIS, GPS, RS and other high techniques make it possible to quick acquisition of airborne or satellite images. Among them, the fast identification of damages to earthquakes from images becomes the key techniques. A new model base system for earthquake damage identification from images has been developed in ENVI/IDL environment to build and management such models. The system realized main functions such as model base building, management and application system creation, model selection and running. By using the model base system, an emergency Earthquake Damage and Losses Evaluate System based on Remote Sensing (RSEDLES) has been developed and applied in practice. The basic components, system structure, key procedures of the model base system realized in ENVI/IDL and its primary application are introduced in the paper.
