Remote sensing data sharing platform for emergency management

摘要

A national emergency spatial data sharing platform approach is a useful and a practical way to promote the discovering and integration of various data sources from different agencies. In this paper, an emergency spatial data sharing architecture used to facilitate resource discovery in the emergency management is presented. At routine time without disasters, the metadata can be shared between organizations so that the appropriate data to be used can easily be discovered. Also, in the event of emergency, this platform can be used to execute the data production plan scheduled by specialists to collect original data from different agencies according to the government's command, so that data can be distributed to the headquarters. On the basis of the introduction of the remote sensing data application in the earthquake, this paper also addresses the data resources (original remote sensing data, metadata, and data product) in the platform, as well as three core issues, data order management, metadata management and data distribution.
