Displaying clusters of media items on a map using representative media items

摘要

Clustering media items includes: selecting a first representative media item that defines a first region, wherein the first region is defined based at least in part on a size of a reduced resolution image associated with the first representative media item; determining a first set of media items that belong to the first region; selecting a second representative media item that does not belong to the first region and that defines a second region; determining a second set of media items that belong to the second region; and sending the reduced resolution image associated with the first representative media item and a reduced resolution image associated with the second representative media item to be displayed; wherein the reduced resolution image associated with the first representative media item and the reduced resolution image associated with the second representative media item are displayed on a map in a non-overlapping fashion.
