The invention discloses a vector data collaborative updating method for surveying and mapping production, which adopts an operation mode of collaborative operation, independent updating and data sharing, and solves the problems of concurrent access, user operation area control, conflict detection, automatic or semi-automatic coordination processing conflict and the like which possibly occur in the collaborative operation process. According to the vector data collaborative editing technology, multiple users can access at the same time and modify and update the database data. A plurality of operators can edit respective operation area data through a collaborative updating strategy based on the same set of database data according to respective operation areas and without data segmentation, background data is updated uniformly finally, and vector updating results of adjacent operation areas are subjected to automatic edge matching and merging. If the attribute changes and the result is updated, the name of the ch
