| 摘 要： | 本文在阐述影像金字塔相关理论（构建方法、影像切割等）的基础上，采用VC2005编程实现了在同一GIS系统中进行矢量数据和栅格数据叠加显示的功能模块。该模块可确定是否加载影像，并根据当前矢量图显示范围自动加载不同分辨率的影像图。

| Abstract: | Based on illustrating the theory of the image pyramid,the function module is developed for the overlay of vector graphics and raster images in one GIS system,using the development tool VC2005.The module can determine whether or not to load raster images and automatically load images with different resolution according to the current vector scope. |
