Abstract
Embodiments of the present disclosure disclose a method and a device for drawing an intersection, a server and a storage medium. The method includes: acquiring road lines of all branches at the intersection based on vector data of the intersection; performing a line-to-surface expansion based on the road lines to obtain road surfaces, and acquiring two side lines of each of the road surfaces; and determining target side line pairs based on side lines of the intersection, and drawing a corner arc at a corner of each of the target side line pairs. Each of the target side line pairs includes two side lines that do not belong to the same road line and are adjacent to each other.
