Abstract

See full text

A mapping system prevents mismatching placement of map labels between adjacent map tiles for rendering digital maps. In particular, the mapping system performs a label placement process that considers labels of a map tile shared with adjacent map tiles in order to prevent labels that intersect the map tile and the adjacent map tiles having mismatching placements. During the label placement process, the mapping system performs a first placement phase to place shared labels of a map tile according to label placement constraints. Based on the first phase, the mapping system identifies intersecting labels that can be successfully placed. Using the successfully placed intersecting labels, the mapping system performs a second label placement phase. In particular, the mapping system first places the successfully placed set of intersecting labels, and subsequently places non-intersecting labels for the map tile according to the label placement constraints.
