基于Google Map的公共气象服务信息显示平台研究

Research Meteorological Service Information Display Platform Based on Google Map

介绍了Google Map API的重要对象、属性和调用方法,利用Google Map提供的JavaScript接口建立了一套公共气象服务信息显示平台构思,将气象数据叠加显示在地理信息之上,实现地图的缩放、漫游、导航、标记等功能,同时有卫星影像、地形、街道等多种地图类型显示方式,并介绍了数据读取、动态标记、事件监听、编码折线以及分级显示等关键技术。

This article introduce the objects,properties and method of Google Map API.The meteorological service information display platform is established based on Google Map API.Meteorological data is displayed on the geographic information,and user can zoom,move and mark on the satellite images,terrain and street map.The key technologies about data acquisition,dynamic marking,event Listening and coding polyline are described.
