Abstract
The current RS-based earthquake emergency system is mainly based on stand-alone software which cannot meet the requirements of massive remote sensing data and parallel seismic damage information extraction after a devastating earthquake. Taking Shaanxi Province as an example, this paper explored firstly the network-based working mode of seismic damage information extraction and data management strategy for multi-user cooperative operation based on analysing work flow of the RS application to earthquake emergency. Then, using WorldWind java SDK, the RS application system for earthquake emergency based on digital earth platform was brought out in CS architecture. Finally, spatial data tables of classification and grade of seismic damage were designed and the system was developed. This system realized functions including 3D display, management of seismic RS image and GIS data obtained before and after earthquake for different user levels and cooperative extraction and publish of such seismic information as building damage, traffic damage and seismo-geological disasters caused by earthquake in real time. Some application to earthquake cases such as 2014 Ms6.5 Ludian earthquake show that this system can improve the efficiency of seismic damage information interpretation and data sharing, and provide import disaster information for decision making of earthquake emergency rescue and disaster relief.
Highlights
As the vigorous development of domestic high satellite and UAV remote sensing technology, the remote sensing data source for earthquake emergency is more and more rich after destructive earthquakes occur
Based on the earthquake emergency prototype system of remote sensing digital earth [7], this paper analyse work flow of remote sensing earthquake emergency using network, and discusses the multi-user collaborative damage extraction mode on the basis of the network and data management strategy, proposed CS architecture of earthquake emergency digital earth platform system of RS applications based on Worldwind
With the rapid development of remote sensing technology and network technology, multi-user collaborative disaster information extraction based on digital earth is an important direction of development of remote sensing
