摘要
本文在分析现存GIS软件中处理多幅不同比例尺或相同比例尺地图的放缩漫游时的不足及其原因的基础上，提出了一种使用地理逻辑窗口动态裁剪快速而安全的多幅地图无级缩放和全区域自由漫游的方法，并对其数据组织和管理作了探讨。
This paper analyses drawbacks and reasons of current software for Geographic Information System (CIS) duling the procedure of zoo - ming and roaming the whole map space made up of many maps in defferent scales. Based on this, a quick and stable method for zoo ming without limitation and roaming map is presented that map is cut dynamically using geographic logical window. And the organization and management for data are also discussed in this paper.
