Abstract: This application provides a method and an apparatus for generating road network data of an intersection area, and the intersection area connects a plurality of roads. The method includes: obtaining data of a road link of each of the plurality of roads, where the road link includes an entry link and an exit link; calculating coordinates of an intersection point of an extension line of the entry link of each road and an extension line of an exit link of a neighboring road based on the data of the road link of each of the plurality of roads, where the coordinates of the intersection point are coordinates of an intersection node; and the neighboring road is a road counterclockwise adjacent to the road; or the neighboring road is a road clockwise adjacent to the road, where two intersection nodes in sequence are endpoints of an intra-intersection link.

Abstract: A terminal port includes a port body and a sealing cover. The sealing cover is assembled surrounding an opening end of the port body, the sealing cover has an elastic extrusion part that extends outside the opening end, and the elastic extrusion part is extruded and deformed along a vertical direction of the port body. The sealing cover is directly assembled surrounding the port body. The sealing cover extends outside an end face of the port body in a parallel manner, and may form waterproof sealing with a housing of a waterproof mobile terminal device.
