摘　　要：建库数据与制图数据的长期分离已不适应多专业领域综合应用和分析的需求,本文针对如何将建库数据和与之对应的CAD制图数据一体化整合为数字线划地图数据的问题,在阐述数据线划地图的概念、管理方式和符号描述以及分析CAD制图数据内容与特点的基础上,研究和设计了数据一体化整合流程,包括数据准备与分析、数据对照规则、数据整合等内容,并以某区域大比例尺建库数据和CAD制图数据为例验证了数据一体化整合的可行性。The long-term separation between databasing data and cartographic data is no longer suitable for the requirements of comprehensive application and analysis in multiple professional fields.This article addresses the problem of integrating the databasing data and the corresponding CAD cartographic data into a digital line map.Based on the concept of data line map,management methods and symbol descriptions,and analysis of the content and characteristics of CAD cartographic data,the process of data integration was studied and designed,including data preparation and analysis,data comparison rules,data integration and so on.The feasibility of the integration of data is verified by taking the large-scale database construction data and CAD cartographic data of an area as an example.
