For the deviation of an operator in the operation process, an edge element to be spliced cannot be identified by a traditional edge splicing method.

Therefore, under the condition that deviation existsbetween the vector elements in the topographic map and the topographic map sheet grids, the elements needing edge connection can be obtained through the vertical lines of the intersection lines to besubjected to merging processing. Therefore, the deviation can be automatically corrected, and the edge connecting efficiency is higher and more accurate.
