Embodiments of a system and method for tile-based reduction of access point location information are described. Embodiments may reduce a set of network access points and respective locations to generate a reduced set. For instance, embodiments may include parsing a representation of a geographic region into multiple tiles. Embodiments may also include, for each sub-area or “bucket” of multiple buckets that make up a given tile, evaluating the set of network access points and respective locations to identify network access points residing in that bucket, and based on a ranking of the network access points in that bucket, eliminating at least some network access points of that sub-area from the reduced set. Embodiments may also include, for each sub-tile of multiple sub-tiles of the given tile, assigning within the reduced set a common location to multiple access points residing within different locations of that sub-tile.
