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.
