Abstract:
1. An apparatus for density smoothing of points-of-interest displayable on an electronic map, the apparatus comprising: a computer-readable medium operative to store: a processor in communication with the computer-readable medium and operative to execute the executable instructions that, when executed, cause: the centroid surface manager to construct a plurality of centroid surfaces from the plurality of centroid values determined by the centroid determination manager; and the zoom level assignment manager to assign a predefined zoom level from the plurality of predefined zoom levels stored in the computer-readable medium to each local point-of-interest extracted by the local point-of-interest extraction manager based on a comparison of the prominence value corresponding to the local point-of-interest with a centroid surface from the plurality of centroid surfaces determined by the centroid surface manager.
