Google Earth二次开发制图接口设计与实现
n interface for drawing features in secondary development of Google Earth
对Google Earth进行二次开发将其与GIS软件进行整合是进一步扩展Google Earth应用、充分挖掘Google Earth潜能的重要途径,而在Google Earth视图窗口上进行图形绘制是其中一项十分重要的功能。本文描述了Google Earth二次开发制图接口(GEDFI)的设计与实现。利用GEDFI可快速实现地理数据中常见图形(点、线段、折线、矩形、多边形、岛多边形)的绘制、图形属性字段设置、属性赋值、根据坐标点集合批量成图等功能,为程序员对GE进行二次开发提供了极大的方便。文章从接口实现的技术路线出发,对其中的关键技术进行了详细介绍。最后文章分析了接口的不足之处主要体现在屏幕取点造成的图形绘制不如GIS软件流畅。
It is an important way for Google Earth to dig its potential fully and extend its application that integrated with GIS by secondary development. And drawing features on its view window is very important when developing and applying Google Earth.This paper describe the design and realization of the interface for drawing feature in secondary development of Google Earth(GEDFI). The interface brings great convenience to programmer. Using the interface, conventional graphics, such as point line polyline polygon and island, can be draw easily; and their attribute can be edited. The paper illustrates the technology roadmap and key technologies. At last the inadequacy of the interface is analyzed.
