In the linkage updating of multi-scale DLG data, the efficiency and accuracy of automatic changed detection is the important basis of the system implementation. This paper briefly introduces the relevant rules and key techniques for the detection, extraction and filtering of changed information, and verified by taking 1:10,000 scale DLG data with 1:50,000 scale DLG data linkage updating as an example .
