Claim 4:
5. A sidewalk network information generation method for causing a processor to execute computer program instructions, the sidewalk network information generation method comprising executing on the processor steps of:
detecting a plurality of end points and a plurality of corner points of a plurality of sidewalk centerlines from sidewalk centerline data indicating the plurality of sidewalk centerlines;
selecting, from among the plurality of end points and the plurality of corner points of the plurality of sidewalk centerlines, a first coordinate indicating a first end point or a first corner point of a first sidewalk centerline of the plurality of sidewalk centerlines and a second coordinate indicating a second end point or a second corner point of a second sidewalk centerline of the plurality of sidewalk centerlines within a certain distance from the first coordinate; and
generating link information for linking the plurality of sidewalk centerlines based on the selected first and second coordinates,
wherein, when the selected first coordinate indicates the first end point, the processor is further configured to generate first link information of the link information, and
the first link information is generated under only a first condition in which a first line segment linking the first end point to another end point or another corner point of the first sidewalk centerline and a second line segment linking the selected first and second coordinates form a continuous straight line.
