区域地震应急专题信息速报系统研究——以江苏省为例
|
摘要
针对地震灾情速报专题信息具有多类型、多时序的报送方式以及数据种类多、信息量大、用户需求广等特点,基于3S技术,实现了多源异构数据的融合,构建了震害背景信息和灾区震害信息的专题数据库,为利用ArcGIS实现空间关联和叠加分析奠定了基础。同时,以江苏省为例,重点研究了面向不同用户需求的快速出图方法。通过对"地震应急指挥辅助决策技术系统"现有专题图成图方法的改进,采用专题图模板和系统调用相结合的方法,利用.NET和ArcEngine,研制了地震应急专题信息和图件快速产出系统,探索了震害空间分布图快速、灵活的出图方法,使出图速度提高了3～10倍,同时,实现了与12322防震减灾短信平台和地震应急指挥辅助决策系统等产出结果在本系统的图形化显示,提升了应急指挥图件产品的实用性及表现力。
Quick report thematic information of earthquake disaster has many characteristics,such as multiple data types,multi-series report modes,massive information and wide user demand.Based on 3S technology,multi-source heterogeneous data were integrated in this study.Furthermore,thematic databases of background and damage information in seismic area were constructed.The study established the basis for GIS spatial association and overlay analysis using ArcGIS.Taking Jiangsu Province as an example,fast cartographic methods for multi-user demand were emphasized.By improving current thematic maps mapping method in the existing system,a fast thematic information and maps system for earthquake emergency was developed by means of combining.NET and ARCENGINE(short for ArcEngine).A fast and flexible mapping method was achieved.The present system can also graphically display the outputs of 12322 Earthquake Disaster Mitigation SMS platform and earthquake emergency command decision support system.As a result,the practicability and expressiveness of the original system were greatly enhanced.
