摘要
针对雷电灾害涉及的关键问题,基于ArcEngine开发平台,结合大型网络数据库sqlServer2005与空间数据库模型GeoIataBase,设计了具有3层逻辑结构的系统构架方案,构建了基于GIS的雷电监测预警与数据处理系统。该系统有效地将各种雷电数据与GIS平台进行无缝对接,并整合雷电预测模式,实现各种雷电数据基于GIS的实时监测处理与预测预警以及高效组织、存储与管理,满足各种雷电信息查询处理分析的需求;为气象部门对雷电灾害天气的监测、预报预警以及各种数据基于地理信息的处理分析等提供了有效的可视化平台,同时也为GIS与气象专业领域的结合进行了有益的探索。
Focused on the key problems of lightning monitoring and forecasting,a system of lightning monitoring,forecasting,and data dealing is devised with a three-layer logical structure based on the platform of ArcEngine,under the support of SqlServer 2005 and GeoDatabase.This system steps beyond the data boundary of GIS and lightning domain,and integrates the lightning forecasting model,realizing the monitoring and early warning of lightning in real-time based on GIS.Meanwhile,the system achieves efficient organization,storage and management of the relevant heterogeneous lightning data including geo-information, and satisfies demands like history lightning data query,processing,and analysis.It provides an effective visual platform for meteorological departments concerning lightning weather monitoring, forecasting and early warning,as well as the comprehensive lightning data processing and analysis based on GIS.It also makes a valuable exploration in combining GIS with meteorological service.
