摘　　要：信息化是当今社会发展的潮流和趋势,信息化产品在知识经济时代发挥着越来越重要的作用,基于地理信息系统的数字地图就是这种信息化产品的典型代表。数字地图充分利用地理信息系统的空间分析功能,将地图转换成带有属性的空间数据库,利用GIS空间查询、检索、提取与复合技术生成各种各样的派生图件,这不仅提高了地图的灵活性,而且为地图实时地表达空间信息提供了可能。本文简要介绍了数字地图的特点和一般过程,并对未来的发展进行了探讨。作为一种新兴产业,数字地图在国家可持续发展中将发挥越来越重要的作用。Informization is a trend of the modern social development.Informized products have played a more and more important role in the knowledge-economic days.Digital cartography based on GIS is a typical representative.The digital cartography transforms a map into a spatial database with the aid of the function of GISts spatial analysis to produce various derived maps based on the techniques of GIS, e.g.spatial inquiring,searching,picking up and composing of data.All of these are not only improve the flexibility of maps,but also provide a possibility to show real-time spatial information of a map.In this paper,the authors simply introduce the characteristics of digital cartography and its operating process and discuss the development of the digital cartography for the future.As a kind of new industry, the digital cartography would play a more and more important role in the course of the national sustainable development.
