Abstract
Abstract A method and apparatus for distributing and displaying maps is disclosed. The method involves delivery of maps that are not dynamically generated. The area serviced by a map server is divided into fixed zones for which there are static map tiles. When a map is requested by a user, the location of interest is sent to the server by the user via the user's client. The server determines which of a plurality of preexisting map tiles contained the location of interest submitted by the client. A central map tile, from this plurality of preexisting maps, containing the location of interest is sent to the client from the map server. The server may also send preexisting map tiles of the zones immediately adjacent to the zone represented in the central map tile. The server may also support a "mini-map" to facilitate user panning of the "greater area", and points of interest, including multimedia descriptions of the points of interest.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
A method comprising: receiving a requested location; selecting, based on the requested location, a first pre-existing map tile and its corresponding miniaturized representation from a plurality of preexisting map tiles and their corresponding miniaturized representations, the first pre-existing map tile containing a representation of an area that comprises the requested location; selecting further a first set of adjacent map tiles and their corresponding miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the first set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first map tile; sending the selected first map tile, the miniaturized representation of the first map tile, the first set of adjacent map tiles, and the miniaturized representations of the first set of adjacent map tiles; and sending processing logic to form a mini map and a visibility area demarcation within the mini map, using said miniaturized representations of the map tiles, the visibility area demarcation denoting an area within the mini map corresponding to the area represented by the first map tile.
Claim 2
Independent Claim
179 words
A method comprising: receiving a requested location; selecting, based on the requested location, a first pre-existing map tile and its corresponding miniaturized representation from a plurality of preexisting map tiles and their corresponding miniaturized representations, the first pre-existing map tile containing a representation of an area that comprises the requested location; selecting further a first set of adjacent map tiles and their corresponding miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the first set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first map tile; sending the selected first map tile, the miniaturized representation of the first map tile, the first set of adjacent map tiles, and the miniaturized representations of the first set of adjacent map tiles; and sending processing logic to form a mini map and a visibility area demarcation within the mini map, using said miniaturized representations of the map tiles, the visibility area demarcation denoting an area within the mini map corresponding to the area represented by the first map tile.
Claim 3
Independent Claim
196 words
A method comprising: receiving a requested location; selecting, based on the requested location, a first pre-existing map tile and its corresponding miniaturized representation from a plurality of preexisting map tiles and their corresponding miniaturized representations, the first pre-existing map tile containing a representation of an area that comprises the requested location; selecting further a first set of adjacent map tiles and their correspondinq miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the first set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first map tile; sending the selected first map tile, the miniaturized representation of the first map tile, the first set of adjacent map tiles, and the miniaturized representations of the first set of adjacent map tiles; selecting a second set of adjacent map tiles and their corresponding miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the second set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first set of adjacent map tiles; and sending the second set of adjacent map tiles and their corresponding miniaturized representations.
Claim 4
Independent Claim
196 words
A method comprising: receiving a requested location; selecting, based on the requested location, a first pre-existing map tile and its corresponding miniaturized representation from a plurality of preexisting map tiles and their corresponding miniaturized representations, the first pre-existing map tile containing a representation of an area that comprises the requested location; selecting further a first set of adjacent map tiles and their correspondinq miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the first set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first map tile; sending the selected first map tile, the miniaturized representation of the first map tile, the first set of adjacent map tiles, and the miniaturized representations of the first set of adjacent map tiles; selecting a second set of adjacent map tiles and their corresponding miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the second set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first set of adjacent map tiles; and sending the second set of adjacent map tiles and their corresponding miniaturized representations.
Claim 5
Independent Claim
228 words
An apparatus comprising: a storage medium having stored therein a plurality of executable instructions, wherein when executed, the instructions operate the apparatus to receive a requested location, select, based on the requested location, a first pre-existing map tile and its corresponding miniaturized representation from a plurality of preexisting map tiles and their corresponding miniaturized representations, the first pre-existing map tile containing a representation of an area that comprises the requested location, select further a first set of adjacent map tiles and their corresponding miniaturized representations from the plurality of preexisting map tiles and their corresponding miniaturized representations, the first set of adjacent map tiles containing representations of areas immediately adjacent to the area represented by the first map tile, send the selected first map tile, the miniaturized representation of the first map tile, the first set of adjacent map tiles, and the miniaturized representations of the first set of adjacent map tiles; select a second set of adjacent map tiles and their miniaturized representations from the plurality of preexisting map tiles and their miniaturized representations, the second set of adjacent map tiles containing representations of areas immediately adjacent to the areas represented by the first set of adjacent map tiles, and send the second set of adjacent map tiles and their corresponding miniaturized representations; and at least one processor coupled to the storage medium to execute the instructions.
