摘要
By expanding its traditional concept and functions, the potential of hawk-eye’s application in cartography was tapped. With the acquisition of the total graph of front view, the client area of front view, the indicator of hawk-eye and the scope frameworks of hawk-eye as the core, various functions of hawk-eye would be realized by combining basic principles and algorithms of the graphic affine transformation with the map demonstration function offered by ArcEngine. Based on the classifications and summaries of the realization methods of hawk-eye, it drew a conclusion that the common hawk-eye and the magnifier window work in the same way, and the location ability of hawk-eye is the basis of dragging function and pulling-boxes function. Hawk-eye has achieved good effects in remote sensing survey and mapping for the development of mining industry.
对传统鹰眼的概念和功能进行扩展,发掘了鹰眼在制图方面的应用潜力。以主视图全图、主视图客户区、鹰眼指示框和鹰眼范围框架的获取为核心,运用图形仿射变换的基本原理和算法与ArcEngine提供的地图展示功能相结合的方法来实现多种鹰眼功能。在对鹰眼的实现方法进行分类和总结的基础上,得出普通鹰眼与放大镜窗口的实现原理相同,且鹰眼的定位功能是拖动功能和拉框功能实现的基础。该鹰眼在辅助矿业开发秩序遥感调查制图中取得了良好的应用效果。
