摘要

The contents and key technologies of GIS based city and county earthquake emergency platform are set forth. These contents are quickly determining earthquake information, collecting earthquake disaster information, aiding government emergency rescue decision-making, and earthquake disaster prevention publicity and social actions. According to these contents, GIS based architecture of the platform is designed, and function modules of the platform are also described. Then key technologies of the development of the emergency platform are discussed, in which much emphasis has been placed on multi-scale based emergency database, SOA based emergency workflow and emergency situation map plotting. Finally, using Nanjing geographic information, Nanjing earthquake emergency platform is developed. And this platform gets good result in a real earthquake emergency drill.
