摘　　要：针对不同比例尺基础地理信息数据联动更新的问题,本文以浙江省1∶2 000与1∶10 000两种相邻比例尺的居民地要素为研究对象,研究了两种比例尺居民地要素联动更新的关键技术流程。文中提出了基于地理实体编码的两种比例尺居民地要素关联关系的构建方法,以及由1∶2 000比例尺居民地要素联动更新至1∶10 000比例尺居民地要素的变化更新传递的处理方法,该研究成果对于不同比例尺基础地理信息数据的联动更新具有较强的实用价值。In order to linkage update the basic geographic information data at different scales,this paper studies the technical process and key technologies for linkage updating of residential land building fea‐tures at adjacent scales by using the residential land building features at 1:2,000 and 1:10,000 scales in Zhejiang Province as the research objects.Both the method for constructing the correlation relationship of residential land building features at adjacent scales based on geographic entity coding and the method for transmission of change update information from 1:2,000 to 1:10,000 scale residential land building features were proposed.The research findings from this paper have good practical values for the linkage updating of basic geographic information data at different scales.
