摘要
突发事件发生后,如何及时高效地掌握周边地理情况,支持各级应急部门抢险救灾工作,是应急测绘的重点工作之一。基于分布式数据库建设的应急测绘专题分析系统能够对应急现场周边地物及人口、法人等专题数据进行快速查询及统计,实现不同尺度、不同用户需求的测绘应急专题数据资源服务,支撑灾情分析与应急处置。试验证明,与传统Oracle数据库相比,采用分布式数据库开展应急专题分析,效率可提升10倍左右。
After an emergency occurs,how to timely and efficiently grasp the surrounding geographical conditions and support emergency rescue departments at all levels is one of the key tasks of emergency mapping.The emergency surveying and mapping thematic analysis system based on distributed database can quickly query and count the surrounding thematic data such as geometry,population,legal person and other special data,realize the surveying and mapping emergency special data resource service with different scales and different user needs,and support the disaster situation analysis and Emergency treatment.The experiment proves that compared with the traditional Oracle database,the efficiency of using the distributed database to carry out emergency thematic analysis can be increased by about 10 times.
