摘　　要：城市基础空间数据库是城市GIS的核心,而数据质量的高低又是数据库建设成功与否的关键。本文在分析城市空间数据的基本特征、数据的特点以及空间数据库中存在的误差来源基础上,结合广州市1∶10 000城市地图数据建库,详细论述了城市基础空间数据建库中进行质量控制的内容及方法。Basic spatial databases of a city constitute the core of its GIS,while the quality of data in the database determines whether the geo-spatial database is well built.Through analyzing on characteristics of the spatial data,features of the data and sources of errors existing in the database,the paper discusses in details the contents and methods for controlling the quality of data when constructing basic spatial databases of a city,taking the database of 1∶10 000 basic city maps constructed by the Guangzhou Planning Bureau as a reference.
