基于GIS的雷电数据可视化地图组件设计与实现

GIS-Based Design and Realization of Visual Map Component for Lightning Data

雷电发生发展于地理空间,具有明显的时空特性,因此在地理信息平台的支持下进行各种雷电数据空间及其属性特征分析具有重要的意义。在ArcEngine的基础上,设计研发了雷电数据可视化地图组件(Thunder Map),按照数据定义层、数据功能层以及地图UI层的3层逻辑结构,实现了各种雷电相关数据基于地理信息平台的可视化表达,并提供了相关数据管理与功能分析的操作接口,为基于地理空间信息的雷电数据处理提供可视化的功能组件支持。

The thunders and lightning occur in the geospace and thus have obvious spatiotemporal characters. It is very useful to analyze the spatial and temporal distribution characteristics of the lightning data with the support of the GIS platform. The visual map component for lightning data （thunder map） is designed and developed to realize the visual display and analysis of various lightning data on the GIS platform, based on the ArcEngine SDK in ArcGIS, one of the mainstream GIS software to implement this component and divided the structure into three logical layers （data definition layer, data function layer, and map UI layer）. A case to illustrate successfully the application of this component is given.
