Abstract

A method of stitching converging path segments to aesthetically label Y-intersections, path bifurcations or splits in roads or the like entails determining which pair of adjacent path segments subtend the largest angle. The path segments subtending the largest angle are reconstructed (stitched together) and a single instance of the label is then rendered along the reconstructed path. Although this stitching can be performed on the client device, pre-stitching server-side is even more efficient in terms of economizing over-the-air bandwidth and onboard processing resources.
