摘要
本文应用ＧＩＳ管理技术对校园地形图进行管理，并探讨了对地形图要素进行管理的途径。内容包括：ＧＩＳ管理目标，系统的实体框架，空间数据的分层组织及内容数据结构，力求使冗余数据得到控制，尽量减小计算机内存，使数据层次清晰，结构合理，以适应空间各种操作。
The campus topographic map was managed by applying Geographic Information System (GIS) and the channels of managing elements of topographic map were probed.The objective GIS management,actual frame of the system,stratified organization of space data and internal data structure were conerned.Tedious data should be controlled as possible to reduce internal storage of computer.The data layers should be clear and the data structure should be reasonable to suit various space operations.
