Specifically, in the production of high-precision map data, production tasks are created in units of map sheets mesh, and each production task of each map sheet mesh has a task number task _ id and a task creation time start _ time.

That is, when the map mesh performs element annotation, the element result record update time update _ time _ a needs to be recorded, and since the association relationship update time update _ time _ b between the elements is updated along with the element result record update time update _ time _ a in a linkage manner, the association relationship update time update _ time _ b between the elements also needs to be recorded synchronously.
As shown in fig. 2, when searching the incremental data, the update time update _ time and the task creation time start _ time of the map mesh with the same task number task _ id are compared, that is, the element achievement record update time update _ time a and the task creation time start _ time in the map mesh with the same task number task _ id and the association between the elements update time update _ time _ b and the task creation time start _ time are respectively compared, and when one of the element achievement record update time update _ time _ a and the association between the elements update time update _ time _ b of the map is later than the task creation time start _ time, the map is considered to be the incremental data.
