国家基本比例尺地图图名存储与应用

Storage and application of the title of national primary scale maps

国家基本比例尺地图通常采用标准分幅的方式进行统一编号和管理。对于我国7种基本比例尺分幅下的庞大图幅量而言,如何解决大数据量情况下图名和图幅号的高效存储,是制图和地图管理中要解决的难题之一。本文提出了一种基于四叉树思想的国家基本比例尺地图空间数据库框架结构,为地图的存储、检索、管理和应用提出了新的解决方案,并探讨了该方案的优越性和具体应用。

National primary scale maps are usually numbered and managed according to standard sheet line system. In terms of the large amount of map sheets under the Seven Basic Scales of China, how to efficiently store the large amount of titles and sheet num- bers is one of the most difficult problems in cartography and map management. This paper presented a spatial database framework under national primary scale-maps based on the concept of quadtree. It proposed a new solution of map storage, retrieval, management and application and discussed the advantages and specific ap.p!ications of the program.
